Small block intake manifolds...

Wow now that is alot of power in that 318. I have seen race block 2 bolt mains (dontk now why they didt go for 4 bolt) make over 600 hp... now thats nuts. Plus it was a chevy... maybe thats why they went with the 2 bolt mains and not the 4 bolt... kind of on the "special minded" side. Thanks 388Dart
