350 hp out of a fairly stock 340

I tend to agree, BUT you really touched on it that it doesn't take much for these little cars to GO, especially the early As. I'm continually impressed with Vixen's slant 6. I know it's not a V8 and never will be, but its torque curve is way different. That makes it very impressive. Even Kitty says all the time "this thing shouldn't be this fast", and she's right. It's just a good combination all the way around. It's a barrel of monkeys to drive.
Shoot brother you know I'd pay for the gas for a ride! Did you end up using that rare Factory head on that car did you shelf that thing?
