All 77 302 heads are the same in every way cc valves combustion chamber runners are the same only difference is head bolt size is 7/16 for 302 and 1/2 inch on 351

Those Fords are confusing. Are all the intakes and carbs the same or is it better to run different manifolds or carbs? I have seen some mustang 2s for sale down south for sale as parts cars

Gary, I just looked in the guide in 1977 and I don’t see the head number you have. Do you have something from NHRA that says that is a legal head. I don’t have any doubt about all the heads being the same, just was wondering why you chose that casting number.

All ford heads and intake manifolds are junk back in the smog days

I’m not sure that they made that casting but you know they don’t make mistakes. If you look at specs for 77 they say show piston as .0235 in hole but it’s .00235 but those as@@/holes don’t make mistakes it’s allways us

Gary,
I'm new to stock racing this year. Per the guide it only shows the D7OE-DA head. With that being said did you question why the D7OE-DC heads was not there? I see they just changed the casting on a head that is legal for my combination so was curious how that happens.

D7OE-DA – 1977-1979, 302, Windsor small-block, 1.78/1.45 valves, 69cc chamber
D7OE-DC – 1977-1978, 351, Windsor small-block, 1.78/1.45 valves, 69cc chamber
D7OE-DC – 1977-1979, 302, Windsor small-block, 1.78/1.45 valves, 69cc chamber

The schedule has been revised, the last sportsman class after the pros will be the Factory Stock Showdown, everyone else is done. No word on tomorrows schedule.


All times are GMT -4. The time now is 10:00 AM.
