I have been going 'round and 'round. I really need to settle on an approach, as I need to get on with the work. As a brief synopsis of the car:
1966 Convertible: much chassis work already done w/ 9" rear, 12" tires under stock sheet metal; lots of structural steel; dual rollbars and no back seat.
R&C Motorsports front end mods DONE - enough room for turbos or a big block. 3" cowl hood allows room for intake tract.
I was going to use a Ford B50 331 + AFR 185's + KB blower @ 12psi...but I'm getting used to a LOT of power in my GTO, and believe this combo will do well w/ a road course suspension in the 2+2. So I've been exploring a stroked 351W + turbo(s). And that is where it gets complicated. There is a catch-22 to this horsepower race for the small blocks, as it becomes necessary to shell out >$2000 for an aftermarket block for >600hp. Those blocks are heavier, and adding turbos, intercooler, etc provide even more weight.
Now I have an offer of a stock 460 to stick in the car. I have been searching far-and-wide for other cars w/ a big-block + MII suspension conversion but no real info so far. Searching the 460 arena shows me that good heads/cam/manifold/carb can make a TON of streetable power.
So...I decided to drag some of you into my own little private obsessional pit! The MII is not the end-all for cornering, and the big block won't help. But I doubt there is that much weight difference from a turbo'd 351W (dart).
Please weigh-in with your thoughts
