I hear ya on the computerized stuff. I'm not a fan, and never will be.
When I was working at a little hot rod shop out in Fallbrook, we put the motor and trans from a 90's-something Corvette, into a 59 Chevy pickup. It was a nightmare. We ended up having to buy some kind of electronic gizmo that interfaced with some other gizmo to make it all work right. It wasn't fun.
Give me a SBC and a Turbo 350 any day. Or even better, an M-21 or 22.
This was my 59 Chevy. I put a 327 and a Muncie in it. Wish I still had it.
