No Core charges or trade-ins required for most engines, see footnotes for the particular engine. Otherwise, furnishing an engine core can reduce some prices considerably.

Aluminum heads option available on most engines. Also, engines built to customer specs available.

All prices are for automatic transmission. Some crankshafts have to be modified or upgraded at extra cost for pilot bearing when used with stick transmission.

#.....This "Daily Driver" has 14" or more of vacuum at idle. It is the maximum in
compression, camshaft size,
intake manifold, and head runner volume
recommended for every day driving. The stock exhaust and torque converter
may be
used but performance versions are recommended for best
performance. Although not recommended, 87 octane gasoline may be used
when the ignition timing curve is absolutely correct.

$.....This engine is our "Almost Daily Driver". It has 10" or more of vacuum at
idle and requires only a minimum extra torque converter stall to allow for a
little higher idle required by the higher duration camshaft.

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.

Each of our engines receive all new high Quality internal components, including 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, usually of our design.


Many people make their engine choice based on the vacuum and idle characteristics of the engine. See the "Idle Type" column above with the engine pricing.

"SMOOTH" idle is as smooth or almost as smooth as a stock OEM engine and has high manifold vacuum, 18 inches and higher. These engines work well the stock exhaust system and torque converter but all engines benefit from a good performance exhaust system and a higher stall torque converter.

"MILD idle can have a slight rumble and has very good manifold vacuum, 16 inches and higher. These engines also work well with the stock exhaust system and torque converter.

"LOPEY" idle is a well defined lope as in the lope or gallop of a horse, and will have good manifold vacuum, 14 inches and higher. This is pretty much the "Muscle Car" idle of most 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. These engines make nice "Daily Drivers" that sound good.

"CHOPPY" idle is a very noticeable performance idle and will have a somewhat lower manifold vacuum, 10 to 12 inches. We recommend quality headers and a torque converter in the 1800 to 2800 RPM range. This is basically a rougher "Muscle Car" idle. We define these engines as "Almost Daily Drivers".

"ROUGH" idle is rougher than "Choppy" and is for those who really want the High Performance sound and are willing to tolerate the "cons" of these type 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.

"STREET/STRIP" engines have a very high to super high duration and lift camshaft and have a very rough "Hotrod" or race type idle. These engines are designed for the "all out die hard" Hot Rodder to only drive occasionally on the street. They will have very low manifold vacuum, need performance exhaust, and a torque converter with a lot of stall. Since we all know that these engines are intended to be abused, their warranty is very limited.

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 footnotes.

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 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. Dyno sessions are not a 30 minute job, it takes most of a day to do the right kind of job. Also we disassemble the oil filter after dyno testing and inspect for debris to ensure that the engine is okay internally. Finally the engine is pressure tested at the crankcase for oil leaks and then painted the brand color or purchaser's choice of color. The carburetor and distributor can be furnished or purchased and will be verified and tuned to the customer's 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!

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

A 12 month - 12,000 Mile written limited warranty (90 days labor only for "Street/Strip engines) is furnished with each Performance Street engine. Also available is an optional 36 Month - 50,000 Mile limited, conditional warranty. For the Highest Quality and best Performance Street engines available, please call, fax or email us for more information or to place your order.

NOTICE: Prices listed are subject to change without notice. Deposits made on special or custom jobs are non refundable after the job has begun! These Performance engines require six to twelve weeks or more to complete depending on the engine. We do not rush Performance engines. Please let us know from the start if you have a hard deadline. Please do not expect definite completion dates. Horsepower figures mentioned require that the user install the recommended performance parts and accessories such as carburetor, intake manifold, 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 piston clearances and faster ramp lift camshafts! This cannot be helped.
