poor man's racing heads
[QUOTE=hotboy454;1582207]@f-bird88 I know this topic is about 2-3wks old. You mentioned something about poor man's racing heads. I was breaking down a motor this week 400sbc in. The casting number was block 3956618 & heads are 3932441 what info could you give me on this. I know you said in a comment back that porting these heads on a 400 would scream. QUOTE]
at one time the 441s would have been a score, i built a 11 to 1 400 with heavyly ported 492s (simler to 441s) for my super street stock and it did scream. I ran around there at half trouttle till the idiots had crached themselfs out and then when there was just 6 of us left i could open her up, get the rears just smokin hot.
Rebuilding those old heads is hardly cost effective today, they dont have the hard seats in them ether the exasut seat is gona wear if it ant worn out already.
