I have a stock 1955 T-bird 292 and have upgraded to 1957 intake manifold, carburetor and distributor. I'm also considering upgrading to rebuilt 1957 "G" heads and a Clay Smith cam with 272 duration and .446 lift based on 1.54 :1 rocker ratio. I believe my stock '55 292 has a 1.43:1 rocker ratio. The upgrade to '57 intake, carb and distributor seems to run fine. I'm wondering if the "G" heads and new cam will cause me any problems considering the lower lift 1.43:1 rockers?
As always, thanks for your expert help.
Steve
