[The guy asked if he could get some info on 427's why are they better ?
Whats with the trashing?]
The 427 was a much better motor than the 390, 408 and subsequently 428 because of the crossbolting of the mains (Some 408 are crossbolted as well) and of the higher nickel content. Also the side oiling system was a big improvement as well for racing operation. The engine was also smaller and lighter compared to other big blocks. The heads are the weak point of the FE and a big block Chevy can make a lot more power because of that, better breathing and stronger rocker system.
