truth, but why do you think they all use a 350 chevy? Not because its a better designed engine. Old school mopar small blocks came factory with shaft mount rocker arms. Chevy guys are paying almost a grand to convert to them. The 340 is the most chronic old school small block ever. The old school big blocks started all this deep skirt block with cross bolt mains that handle any kind of seriouse power. 1000+. Finally I’ve seen video of a bone stock srt8 300 putting down some extremely impressive times.
