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.
Now I can't tell if the rocker covers are 4 bolt or 6 bolt. Pic is too
small, but they do look like Chevy or Buick covers, and not the Ford
shape...
AND now I'm looking at intake, it does not have the Ford shaped runners.
The manifold is too flat.
The layout is just like a 352 Ford, or 390/427/428 FE engines. If the
boat is older, this could be the case, but the rocker covers still look
too small for a 352.

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
