I just put down 395rwhp/387rwtq with my F14HL corrected. Uncorrected was 404rwhp/39xrwtq. I had colder plugs gapped at .35 in the car, not sure if running a hotter plug like a TR55 would have made a difference or not. I'm very happy with it. The car pulls hard up top and drives like stock. I was also happy that I didn't have to rev the living **** out of it to make power like I was expecting. Here's my thread in the dyno section if you want to check out the graphs... https://ls1tech.com/forums/dynamometer-results-comparisons/912753-f14-highlift-cammed-98-ss.html

I made 397/37X 4 or so years ago with a 224/228 581 112 bolt on 99 Z with 4.10's. To be fair, my car pulls quite well above 4000 rpms now with heads etc. I won't make my final judgement until I get some good passes in. Alan is cool enough, but every shop wants to have a "signature" cam or something to make them different.

Full exhaust, LS6 intake, ported TB, UD pulley, lid. I might be going to the track tonight so I'll post up what happens. I think a snapped 10 bolt might be in the forecast

Well, I don't have the F14 but I DO have the F13, standard version.

I made the power in my sig with that and Patriot Stage II heads. I absolutely love the cam. I think the "high-lift" version is kinda pointless. I felt the duration-to-lift spec was pretty complimentary to the head ports, valves, etc. that I picked for my setup.

Numbers don't lie. I'm happy with my power and everything turned out great.

I have a few recent threads with an idle video and the dyno chart if you're interested.
