318 poly in 68 cuda
I would listen to these other guys, I just spent 3500 on a poly for my 66 fury. Camcraft cam, Bumped up compression to 9.5, the weiand 4 bbl, shorty headers. It runs good and it goes good for what it is, but it was also original to the car. I wouldn't build another one. Get an LA, they are cheep to find if not free, and the parts and power will be easier to get.
