Incompatible with stock compression ratio and will need minimum 2200 stall converter.

Ok

Cam puts out to a point and then the the engine must change. If you bought the intake and cam as a kit you may be able to go up one more but call Edlebrock they give ok tec. If you want more you will need more flow (porting), bigger valves, and a higher compression ratio. These mods will sometimes require a new botom end. There is software out that will give you expected outputs for given components, I think comp has it and you may pay but it will warn you when you go to far. If you don't want comp's software then google engine simulation software!

That cam is a little stronger than what I have in my new 383 at 10.5cr and I believe I hit pay dirt with it. That is a lot of duration for a 350 , I agree.

i read somewhere that comp cams said that the biggest cam you can use with no stall is a xe268h Cam and Lifters, Hydraulic Flat Tappet, Advertised Duration 268/ 280, Lift .477/ .480, Chevy, Small Block, Kit. would this be better. i wish that cam line was open on sundays i a goin to call monday.

If you're hell bent on running that cam in your truck you'll want a 3000stall converter and a 3.73 4.10 gear. more with real tall tires. otherwise use the cam u have.

If you want to have a cam with "a step up" from the Edelbrock performer cam. using the stock converter, use this
SUM-K1103 Summit camshaft. Either carb is fine.
