Now when you start moving up into the stage 3 stuff like VVT-3, Polluter, SSi-3/4...etc, using high seat pressure dual springs, and revving the engine to 7200rpm, then it would be wise to use something like a Johnson 2110. I would say based on looking at different cam and spring packages. LS7 is probably ok up to Stage 2 or cams where the engine rpm isn't going to exceed 6800rpm and require a heavy spring to keep things in control. jmo ymmv.

Well that’s what I’m using. GPIs SS4 cam and the Brian Tooley springs. I typically shift 6700-7000rpm. Rev limiter at 7200. I really wish I would have upgraded. I just knew at the time to upgrade the trunion to get rid of those needle bearings. Would I have known the ls7
Weren’t that great I would have optioned the Johnson lifters as well. I asked GPI what they would recommend upgrading and they said ls7 lifters are fine |

His tsp vvt2 cam was early days before 0 degree lock, you think that will offset losses under 4000? Plus I will have ported stock manifold and think with my tuner he can tune with no loss anywhere.

Why did you settle on VVT2 instead of 3?
