I have to build a new motor for my 1992 GMC k2500, I have a motor from a 1990 Chevy k2500 5.7 that I’m gonna build for it, I’m gonna port and polish the heads, and stud the motor, can anyone tell me a good cam for it, I’d like to have good torque, it’s a TBI as well I want something that gives it a mean idle but will also be reliable
