BBC Heads 820 vs 292
Has anyone tested these two castings back to back, or the 241? Whether it be on flow bench or dyno. We want to do a new set for my dad's car as his seats are beat pretty bad but before I hunt for castings it would be nice to know if one is better than the other to start with. Thanks.
