thinking of doing the swap input wanted

Black 69 Dart said
Is there any differance in the blocks? Is one stronger then the other? I am going to shoot for 550hp and 500 ft lbs. The car runs mid 11s and I don't want to slow down but gain driveability. Has anyone used a big stuff 3 engine managment system? Which accessories hit the frame? I need an alt and thats about it, I would prefur to mount it low as it makes for a nicer look under the hood in my oppinion. Sorry for the questions?

Hey,Getting questions answered is what are what we are all here for!!! The 5.7L block has a small bore 3.910. The 6.1L has a larger bore 4.070, as for strength, they are both prety strong with 4 bolt mains. Your best bet is probably a stroked 5.7L to 392 cid with 6.1L heads. That should make for a good running engine and get you what you want.
