Description: Street/Strip. Iron Head Long Block. M-6250-E303 Camshaft - Auto or Manual Transmission.

302 cubic inch. Engine dyno-tested at 270 Bhp using a 780 cfm Holley carburetor and shorty headers. 9.0:1 compression ratio (nominal). Ford Racing high-flow cast iron cylinder heads and GT-40 value train. Ford Racing high performance hydraulic roller camshaft M-6250-E303, roller lifters and standard rocker arms. Fits kit cars, street rods, Mustangs, Fox-bodied cars, and trucks with minor modifications. Depending on your application, the timing cover and/or water pump, damper, oil pan and pick-up may need to be reused from your original engine.

A new long block assembly, built at Ford's Cleveland engine plant. It goes down the same production line as 5.0L HO engines, and is built with the same quality controls as a new production engine. With minor modifications it will also fit earlier models and vehicles with automatic transmissions.
A new current production long block assembly that includes theblock, crank, rods, pistons, timing chain, standard rocker arms, roller tappets, push rods, oil pump and pickup, oil pan, valve covers, front cover, water pump, flywheel, spark plugs and related long block engine parts-to which SVO engineers have added:

*SVO GT-40 aluminum cylinder heads M-6049-Y302. They flow significantly better than production 5.0L HO heads.
*SVO GT-40 valve train kit. It includes springs, retainers, keepers, seals and premium stainless steel swirl polished valves with undercut stems. Intake valve diameter is 1.84" and exhaust valve diameter is 1.48".

Includes SVO high performance hydraulic roller camshaft M-6250-E303. It provides significant horsepower increases above 2500 RPM and good low-end torque. Valve lift is .498" on both intake and exhaust. Duration at .050" is 220 degrees on both the intake and exhaust.

Installation notes:

Some or all of the following items may need to be changed from your original engine or modified for proper installation:

*This engine has a front sump oil pan and pickup, Explorer "short style" timing cover and water pump, Explorer harmonic damper and EFI valve covers.
*The front sump oil pan may work for many late 60's and early 70's Ford passenger cars.
*The Explorer timingchain cover may work for 1994-95 Mustang, and 5.0L Explorer. For other applications use your original. M-6059-D351 replacement front cover may work for most other common applications.
*The water pump included may work for 5.0L Explorer.
*The valve covers included should work for most Mustang EFI applications.
*The damper may need to be changed to your original 1981 or newer (part number E4TZ-6316-A).
*The flywheel included should work for most 157-tooth manual transmission applications. For C-4or A0D automatic transmission applications use your 1981 or newer flexplate or order E2AZ-6375-A from your local Ford Dealer for a 164-tooth flexplate.
*Distributor with steel gear should be used to be compatible with the camshaft included in the engine.
*Firing order 1-3-7-2-6-5-4-8 (5.0L HO and 351W order).
*Built with current production parts.
