Could someone give me some info on these big block heads. 3964290/3964280 E 11 70 They are on a 454 in a car I just bought with receipts for $750. I know they were cast may 70 but just wanted the good,bad, or ugly. Thanx
They were represented to the buyer as 98cc . Is a lower or higher cc # more desirable? My dad used to preach to me " never be so smart you can"t learn". Thanx guys. John
