2 bolt or 4 bolt mains. pontiac 455
well the 455 i got has 2 bolt mains, but is drilled for the 4 bolts. the block is already line bored for the crank and is ready to be put in. is it worth it to spend the extra money (idk how much its going to cost) to have the 4 bolt mains?
its going to be a 10:1 motor pretty agressive cam.
Also is Crowler? (i think thats the name) are they good cams?
