How about the cross member, a 4200 & 4L60E trans bolts right onto a stock cross member? If so, what cars will bolt right in?
Nova ,Camaros, etc.

Need to change the fuel system, have a return line?

What tuning software is needed to tune? EFI fuel pump.

How much for the software, or for someone to program it?

How much boost pressure can the stock intake manifold before it comes apart?.
