Some engine prices include the core charge and some engine prices are based on using the purchasers engine core. We can almost always furnish the core when needed. The price of the core often depends on the market value at the time. See the particular engine's footnotes to see if cores charges apply, footnote u.

Aluminum heads and roller cam options are available on most engines. Most prices are for automatic transmission. Some crankshafts have to be modified or upgraded at extra cost for pilot bearing when used with stick transmission. See footnotes.

Note: 3X2 carb versions will be lower horsepower than advertised because the factory intake and carbs are more restrictive.

?.....This is our true "Daily Driver" and cross country Performance engine. It also makes
       an excellent towing engine with its mild idle and high vacuum.
        If you are not hung up on the Classic Muscle Car idle sounds known as;
        Lopey, Lumpy, Choppy, Rough, Racy, Gallop, Bubbly, etc, then
        this may be the engine for you.

#.....This is our "Daily Driver" with a "Nice Muscle Car Idle". It will have good manifold
       vacuum, usually 14 inches or more. The stock exhaust
       and torque converter may be
used but performance versions are
       recommended for best performance. Although never recommended, 87 octane
      gasoline may be used when the ignition timing curve is absolutely correct.
      This is the maximum camshaft recommended
for overdrive and lock up torque
      converter applications.

$.....This engine is our "Aggressive Daily Driver" with a "Great Muscle Car Idle". It has
       fair manifold vacuum. Usually around 10 inches which handles most vacuum
       operated accessories. However, it does require some extra torque converter
       stall to allow for a little higher idle required by the higher duration camshaft.
       Around 2500 RPM stall is needed to realize the full performance potential of this

!.....This engine is a weekend or occasional driver, NOT a daily or distance driver!
      Also, NOT recommended for use with overdrive or lock up
torque converter

CAROLINA MACHINE ENGINES is an expert at extracting the most horsepower and producing the most dependable High Performance Pump Gas street engines available. We are able to do this because of our long time involvement in racing and performance street rodding 'and' because of our experience as a Production Engine Remanufacturer (PER).

Although we produce "high end" Performance and Race engines with expensive parts, we also produce more economical engines that use one or more of the stock OE parts such as block, crank, rods, heads, oil pan, etc. These engines can produce amazing horsepower and give good long service when "done right". We have the ability to accomplish this because of knowledge and experience gained from decades of racing under basically "stock" type rules and regulations of the various sanctioning organizations.

Our Performance Crate engines receive new high Quality internal components such as performance valves, forged or hypereutectic pistons(when available), moly rings, brass expansion plugs, premium rod and main bearings, cam bearings, pushrods, valve springs, rocker studs, hydraulic lifters, rocker arms, timing chain set, and a specially chosen and dyno proven performance camshaft, often of our design.


Many people make their engine choice based on the vacuum and idle characteristics of the engine. It can be absolutely critical to one's satisfaction to choose the correct idle type (cam size) for the engine. Most of us are happy with the sound and drivability of our "LOPEY" idle camshafts "BUT" some may find it too rough and some may find it not rough enough. Please put some thought into it!

For normal street use, we recommend either our "Mild, "Lopey", or "Choppy idle version engines. Our Mild idle has a hint of performance sound, good vacuum, and can be driven cross country. Our "Lopey" idle has a definitely noticeable performance sound and can be driven daily and short to medium trips. Our "Choppy" idle has the definitely performance "Chop" and can be driven daily but is not recommended for long trips or as primary daily drivers. Keep in mind that one horsepower per cubic inch is a good rule of thumb for a performance daily driver and the more horsepower per cubic inch, the less drivability. Also and maybe more importantly, larger cams sacrifice the lower RPM torque and horsepower. This lower RPM, 2000 to 4000, is where we mostly drive. This is where the fun and tire spin happens. Big cams make big power but are not as much fun for many of us.

"SMOOTH" idle is as smooth or almost as smooth as a stock OEM engine and has high manifold vacuum, 18 inches or more. These engines work well with the stock exhaust system and torque converter but all engines benefit from a good performance exhaust system and a higher stall torque converter. This is absolutely a true "Daily Driver" but more camshaft is needed for higher RPM power and the "Muscle Car" idle sound.

"MILD" idle can have a slight rumble and has very good manifold vacuum, 16 inches or more. These engines also work well with the stock exhaust system and torque converter. Again, a true "Daily Driver" with a hint of "Muscle" sound.

"LOPEY" idle is a well defined lope as in the lope or gallop of a horse, and will have good manifold vacuum, usually 14 inches or more. This is pretty much the "Muscle Car" idle of many cars of the 1960's and 1970's. These engines have the largest cam recommended for the stock torque convertor. They are the maximum in compression, camshaft size, intake manifold, and head runner volume recommended for every day driving and for using overdrive, and lock up torque converters. Although no true performance engine should be classified as a "cross country driver", this is as most cam and compression that we would recommend for occasional long distance driving. These engines make "Great Daily Drivers" that have a "Nice Muscle Car Idle".

"CHOPPY" idle is a very definite performance idle and will have a somewhat lower manifold vacuum, usually 10 to 12 inches. We recommend quality headers and a torque converter in the 1800 to 2500 RPM range. This is basically a rougher "Muscle Car" idle. They are daily drivers but not distance or primary drivers. We define these engines as our "Aggressive Daily Drivers" with a "Great Muscle Car Idle".

"ROUGH" idle is rougher than "Choppy" and is for those who really want the a super Hot Rod sound and higher peak horsepower numbers. Also, they must be willing to tolerate the down side of these type street engines. With the "Rough" idle cam, the vacuum will be under 10". Also this engine will need headers and performance exhaust system. A 2800 RPM or higher torque converter is recommended. A vacuum canister or electric vacuum pump may be necessary. This engine is not recommended for daily driving, overdrive transmissions, or lock up torque converters because it may have a rough or jerking motion at lower RPM cruising.

"VERY ROUGH IDLE STREET/STRIP" engines have a very high duration and lift camshaft and have a very rough "Hotrod" or race type idle. These engines are slightly toned downed race engines. They will have very low manifold vacuum, need performance exhaust, and a torque converter with a lot of stall. Very light street driving only and 100% racing gasoline is recommended when WOT is in use.

All vehicles will perform better upon acceleration with a performance torque converter. We can advise you and supply you with the correct torque converter.

Many of our engines receive new aftermarket cylinder heads which flow much better than the stock OEM heads, therefore increasing the horsepower output significantly. "Stroker" engines have a crankshaft with a longer piston stroke than original. Some engines are all "Brand New". See the footnote column for each engine.

Our "Complete Engines" include the oil pump, oil pump screen, oil pan, oil filter adapter, oil filter, dipstick, timing cover, balancer, valve covers, intake manifold, and spark plugs.

Engines are expertly machined, balanced, blueprinted, plate honed, line honed, decked, and sonic tested. Engines are then assembled by a highly capable technician and spin tested with heated break-in oil with the proper additives. The oil pressure, compression and oil circulation is carefully verified.

To remove the possibility of our valued customers experiencing problems with break-in or initial problems of any kind, we dynamometer test "EVERY SINGLE" complete version using comprehensive "break-in" procedures including the correct break-in motor oil and oil additives. The actual dyno sheet for that particular engine showing the horsepower and torque at various RPM points is provided with the engine, no copies! A dyno session is not a 30 minute assembly line job, it takes most of a day per engine to do the right kind of job. Also we break open the oil filter after dyno testing and inspect for debris to ensure that the engine is perfect internally. Finally the engine is pressure tested at the crankcase for oil leaks and then painted. When provided or purchased, the carburetor and distributor will be verified and tuned to the engine to ensure a 'no hassle' installation, just install, fire it up and it is ready to go! Carburetors and distributors are notorious for not allowing the best horsepower and drivability. They can make a good engine look bad. The dynamometer does not lie! Always have your engine dyno tested with the carb and ignition you will be using no matter who builds it!

We guarantee the quality, dependability, and accuracy of our engines. Some engines are not legal for sale or use on pollution controlled vehicles.

Smooth, Mild, Lopey, and Choppy Engines come with a 12 month-12,000 Mile written warranty. Rough idle engines carry a 90 day CME labor only warranty and "Very Rough Street/Strip" engines carry a 30 day CME labor only repair warranty.

NOTICE: Prices listed are subject to change without notice. Refunds for deposits and cancellations are at CME's discretion and are subject to fees up to 25%. Performance, Custom, Special, etc engines often require six to sixteen weeks or more to complete depending on the engine. We do not rush our engines. Please let us know from the start if you have a hard deadline, we may have to decline. Please do not expect definite completion dates. We ask that you send us emails anytime, asking for updates since we cannot make routine calls or emails. Also make sure that you have all quotes and other information in print (emails) as we do not accept verbal assertions. Horsepower figures mentioned require that the user install the recommended performance parts and accessories such as carburetor, ignition system, and exhaust system for those figures to be accurate! Performance engines WILL be noisier than OEM stock engines especially when cold. This is due to centered pin pistons, extra clearances, and faster ramp lift camshafts! This cannot be avoided. These are not warranty issues. Requests for pictures or videos during the building process cannot be guaranteed! Also not guaranteed available are spec sheets, build sheets, etc. Some information is proprietary and not available at all and the rest is time consuming to produce. When available, such special requests can be at extra cost.
