Question about cam?

Sooner Cole · 08-20-2017, 12:57 PM

Has anyone swapped a cam on 2017 ZL1. Would you use a VVT cam or a VVT Delete? Anyone have an opinion on why one is better than the other? Thanks!

Dont have a pro or con on VVT, but here are the crate motor specs for the VVT cam:
Camshaft Type (P/N 12642245): Hydraulic roller
Valve Lift (in.): .492 intake / .551 exhaust
Camshaft Duration (@0.050 in.): 189° intake / 223° exhaust

No reason to delete the VVT, does nothing but good. Although you will have to use a phase limiter...

Some tuners prefer the VVT delete on performance motors. I'm just not that familiar with the pluses and minuses of each, so I'm asking for opinions. I followed your build, nice work! Did you get it tuned yet? I'm curious to see the final numbers.
