Hey guys. I have a 28 ft 1970s SlickCraft with a GM engine (don't ask
which kind. I or everyone I talk to can't figure that out). What
kind of engine is this? [IMG]http://i17.photobucket.com/albums/b71/

Also, do you guys have a firing engine for this? Thanks! aim,

Distributor in front...

Not a Chevy.

Not an Olds.

Not a Pontiac.

Not a 318/340/360 Chrysler either.

Distributor at front, in intake(not timing cover), & vertical/not slanted...

Not a Buick.

Not a Cadillac.

Not a 383/400/426/440 Chrysler either.

Pretty much leaves us with FORD.

Wide manifold - high deck = 351 Windsor. The thermostat housing to the
starboard of the distributor confirms this. It's a Prestolite
distributor. 2bbl carb = ~225 hp. 4bbl carb = ~240-255 hp.

There are 4 different firing orders depending on the camshaft, & engine
rotation.

The typical 351W marine cam has a firing order of 1-3-7-2-6-5-4-8 for
standard rotation engines (CCW rotation as viewed from flywheel) shared
with the 5.0 HO & 351W cars.

The order is 1-8-4-5-6-2-7-3 for reverse rotation engines (CW rotation
as viewed from flywheel).

The 302 cam is rare in 351W marine applications(although it is a direct
fit), it is slightly different than the above orders:

1-5-4-2-6-3-7-8 CCW
1-8-7-3-6-2-4-5 CW
