disc brake swap turn full resto

So with me being on night this month and bored I decided to check the rockers and sure enough the intakes were too tight and exhausts were too loose. Last time I did it running and up to temp. This time cold and not running. My buddy came over and we took the valiant out for a spin. Running some curvy back roads doing about 50mpg. Almost no body flex and alot more power. Next weekend I'm going to ditch the holley 1945 and try installing the holley 350 with the lokar throttle and kickdown cables. The holley 1945 runs great but I'm looking for a bit more power and then later maybe install a turbo.
