Big block rebuild - where do you buy your parts?

4.10s will work, BUT you need a GOOD converter. I would put a tight 3500-4200 behind it. You can cruise around like a stock converter and it will flash to 3500-4200 when you launch it. You'll need to call and actually talk to a converter company though. Word to the wise. Don't cheap out. The converter can make or break your build.
