score! but i need help

I'll say agin. Dont waste your time. I'm also curious..why the 400 hp level? A properly set up A body will run in the 13s with a bit less. that's faster than most mustangs (unmodified) and way faster than Naturally aspirated imports. I think you'd be better served if you just give an ET you want to run, and where you need to be able to run it.
