Joel,
I've looked at a lot of things, but I have to have 4 seats with reasonable back seat room since the whole point was to be able to take the whole family around in it.
That's the reason for an early Mustang. The '65 coupe weighs 2500-2800 lbs, depending on options. If I put an aluminum front subframe kit and an aluminum engine I should be able to keep it at 2800 lbs even with upgraded interior, sound deadening, transmission, etc. That's pretty damn light. I still want to go turbocharged, but much more mild in concept, probably 600 RWHP range. I may say screw it and go ITBs on a big inch motor instead, but we'll see. 500 HP is just as good as 600 HP to me, really.
The British cars are just too small for me, unfortunately.
