5.7 hemi build

[Shadow9198]

I have a 5.7 hemi with a spun bearing. I want to build this engine up and it will be boosted and retro fitted into an old car. I saw i can buy a 6.4 stroker kit but from what i heard the walls get pretty thin. I was thinking i would build it to a 6.1. What all would that require?

I would just get a kit for a 5.7. Some have sonic tested the blocks and went to a 4" bore but even staying at 3.97 is big enough. A 4.05 crank will get you a 392, a 3.79 gets you in the 366 neighborhood. Cubic inches with a turbo only makes you need a bigger turbo.
