Help,
I have I beleive to be a early model 351w, it has the L-shaped water passages.
It also has 8 intake bolt holes on the heads. The aftermarket intake that I used when building the motor the first only had provisions for 6 bolts on each side of the intake. I had problems from the very start with small amounts of water getting in my oil. I have torn it apart again. I purchased another aftermarket intake (Edelbrock #2181) only to find it has 6 bolts on each side of the intake as well.
Is this acceptable?
Why the missing 2 bolt holes?
Any intake install tips?

Thanks,
Ranchero Gary

Hey Gary you have a 351 Cleavland motor (8 bolts for the head and intake) another ID trick you can use is that the water neck where the thermostat goes on the Windsor models face the radiator where as the Cleavland models face up to the hood *side note the 302W's deck height is 8.2" where as the 351W is 9.48" 1969-1970 & 9.5" 1971-1996 the 302 [BOSS] 1969-70 Cleavland is 8.2" 351C 1970 - 1974 is 9.2" & the 351M/400 1975-1985 10.297" Ford Racing Performance Parts - [2010 Catalog] will let you download their catalog as a .pdf and will give you a MASSIVE amount of info such as deck height and really cool parts too and NO I don't work for them I d/l their catalog every year they come out.

The W has the thermostat in the intake & the C has it on the block. Pre '77 W has 8 intake bolts per side & '77 & later has 6 bolts per side. You might have to look on EBay for the 8 bolt intakes.
