I don't beleive so. It depends on the timing of the opening and closing events of the valves. The overlap at TDC tends to have the greatest impact, but the overlap at BDC will also affect it somewhat, but to lesser extent.

Talk with the manufacturer of the cams you are looking at to find out how the cams idle. I beleive that the GTM and BC Stage 1 cams, and the JWT S1 and S2 cams should be fine. Please note that the JWT S2 cams are milder than the JWT S1 cams.

I think I already provided a link to the JWT cam profile chart, but here it is again just in case I didn't:

I didn't look at that link until just now. Note he was running 114 octane race gas at the higher boost/hp levels. He only made 448 RWHP on pump gas with a 1.18 correction factor. That means his actual measured RWHP was 380 RWHP. Stock blocks do that all the time.

The corrected 560 RWHP correlates to 475 RWHP actually measured, and the corrected 597 RWHP correlates to 506 RWHP.

Even then, his testing was done on a DynoJet. The actual measured values correlate to approximately 342 RWHP, 428 RWHP and 455 RWHP as would be measured on some other dynos (e.g., Dyno Dynamics, Mustang, etc.).

Last but not least, here is what he said about his dyno session:

"For ***** and giggles we decided to turn up the boost and see how far the motor will go before it pops."

As others have said, if he runs that motor at 15-16 psi at sea level - KaBoom. He might get by for a little while with that boost level at his 5800 ft. elevation, but not for long, as he obviously knows, hence his comment above.

Again, you have a lot more research and learning to do, as evidenced by your posts. My advice, get a good tuner to guide you in your decisions. Otherwise, you may end up throwing away alot of $$$ and creating alot of frustration for yourself.
