My new cam vs OLD TR220
#51
Yank tt3000 and 220, no low end, good from about 5000 and up. Just not a good combo for a big truck. The z06 cam, with that tt3000, much better tq, wide lsa lets it have such a wide powerband and rev high. This setup is better suited for your current driveline imo and I think you'll see some mid 13's now.
It runs too good
