I am building a 350 for my rat rod, 1953 3 window chevy pickup, and I have a question on cam selection. I have the short block built. I have had the motor bored .040 over, new crank and .040 speed pro flat top pistons. The heads I have are 906 vortec heads. I had them worked, new springs and the heads cut to allow for .550 lift. valve job and the heads were decked. I am trying to figure out what cam to run. I plan on having a 3.08 rear end and the trans is manual. I want it to sound rough at idle and I want it to run well from at least 2000-6500. I dont have an intake or carb yet. Thanks for the help.
