I did something similar to my 406, installed a larger cam with alot of overlap & lost bottom end, even with 4.11s & a 4200 stall i wasn't impressed, had the timing at 37* all in around 2500 rpm, My compression is at 10.4 with 64cc "iron eagles", My piston volume is 8cc, You will be fine on pump gas with 11.1 on "aluminum heads", but your tune needs to be right, plus run a colder plug.

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.
