I was talking about 350's in particular. The Vortec might be rated higher, but has no noticable increase in power and a definite decrease in gas mileage. Believe me, I know. My dad owns a GM pickup with each engine. I don't know if you have been around Chevys much, but most people who are actually prefer the old TBI system.
