What i did'nt like about my cam was its 108 LSA, your better off with a larger LSA 112-114 with higher compression engines on "pump fuel", I went back to my milder cam & its loaded with torque, It even runs faster ET & MPH with the smaller cam, Its all on how much time you want to spend tuning it, plus your going to need more stall/gears with that cam.

My advice, change the cam, its not that hard,then install something that'll work with your 3000 stall & 3.73 gears, you'll be much-much happier, Heres the cam i'm running with a 2800 stall & 3.73 gears.

Lunati "barebones" line.

465/488, 224/234 @50, 112/107 2000-6000 RPM

Its runs great on 91 octane & 210-215 cranking pressure

It pulls around 16 inches manifold vacuum, sure its a bit mild, but i'm running 12.3s @ 109-110 with this cam.
Didn't really want to change anything in the engine i'm trying to get the most from what I have already
