I ask only to better understand the intent behind your question.

It is a gm crate tbi with a small lunati cam. the motor is out and at the machine shop because it ate the thrust bearing at 20,000 miles.
It ran fine before but i was thinking while it is out and tore down i might put a roller cam in it and possibly upgrade the heads. the motor lives under 4,000 rpm. mostly under 3000.
it is a 89 v2500 burb, 5.7, 4l80, 456 gears, 34 tires. mostly for towing, camping, running around town.
