You're making me want to hop up the 318 Poly in my 64 D200 flatbed with 4sp and 5.13 Dana suregrip.
I did pop a wheelie onetime with a little dirt in the back.
The truck is a mean stop lighter when not carrying a load. lol
I've had interest in doing a poly. Get the dual quad intake. My sister had a '62 Dart with the poly, and it beat my brothers 500 C.I. Cadillac to 80 mph before the Caddy went around it.... LOL
