Ok, which 5.3L would be best? I still want aluminum heads and an iron block I think.

Looks like the Mast ECM is a pretty nice and pricy unit. But I'm not sure it's in the budget. A cam/spring kit should be no issue. Long tube DT headers, and magnaflow mufflers. What other conservative modifications should I consider? Is the weight savings of an all aluminum block worth it? Especially since a blower is possible later?

Any suggestions for A/C compressors? Mounting location? Could I use the one the motor comes with? This is a 70' C10.
