do 351c heads flow as much as 351w stock heads say both form 1970??? do they ahve the same potential that 351w heads have??

 

c heads flow better

 

what are the specs on the "c" heads. i am trying to find something.

chamber size? port sizes? flow numbers? valve sizes?

Thanks guys.

 

finally found some:






1970-71 D0AE-G
D0AE-H
D0AE-M
D0AE-N
D0AE-R
D1AE-GA
4V (Closed)
62.8 cc
2.19"
1.71"
2.50 x 1.75"
2.00 x 1.74"

 

I would run the open chambered heads. My buddy just picked up some Yates cylinder heads yesterday. They look incredible.

 

closed chamber > open chamber

the only reason people favored the lower compression open chambers was their smaller port size. civy is gonna be using a single plane clevor style intake and will be making big power up top.

civy, your gonna want gears cause this motor is gonna wanna run strong in the higher RPM range.

 

like how high of a rpm range. i dont want to spin over 7200 rpm. But i read it should run in the 6800-7000 range. What gears???

 

get aussie heads, small chambers which is like the 4v, and small ports for street like 2v heads.
