Valve timing for 350 TPI roller cam
Valve timing for 350 TPI roller cam
Does anyone have the valve timing events for the 350 TPI roller cam? ( the 202/206 .403/.415 115 LSA cam) I know it's super lazy to ask instead of doing it myself , but as old as these cams are I bet the numbers are out there (Fast357?). I'm pulling the peanut cam from my 305 TBI this weekend and either this cam or a Vortec roller is going back in with 1.6 rockers. I have the events for the Vortec cam and I'm curious to see if 10+ years of tech make it the better choice over the TPI roller. Thanks to all.

The Vortec cam is the better choice, because it's earlier IC is a better match to your no-flowing intake ports. The Vortec cam will give up at a similar RPM to your heads.
The info you asked for is -14 36 37 -11
You'll lose low-end torque because of the late intake closing, and your top end will still be weak because of your swirl-port heads.
