I'm looking for more low to mid-range torque and was thinking about using the factory 350 RamJet/GM HT383 crate motor roller cam; 196/206 @.050, 431/451 with lobe centerline of 109.
Would be going in my '93 truck with 350, edelbrock headers, edelbrock performer carb intake with tbi adapter, vAFPR, Ed Wright Stage 1 chip.
Would the longer than stock duration screw with my ECM?
Thanks, SC.

 

I think that the cam would work just fine. The LSA seems a little low though for the stock chip. That cam should give you a nice torquey motor.

 

I just put one in my 94 truck 350 tbi 209/216-435/455 112 lsa.And it has more torque & I think better gas milage.Took me 1 day & 1/2.I like it alot.
