Testing out all of the new summit pro cams ? Any interest to see results ? As most of you know I installed the SUM-8715 stage 1 ghost cam in my trans am, now I'm curious if anyone (including summit racing) would be interested in seeing more tests with the rest of the line up. My car is very easy to change cams in, as I already have .660 duals, LS7 lifters, no a/c on it, etc .. and I can hop on the same dyno any time I need to. My tuner enjoys this kind of stuff and would have no problems making rips on a couple different cams if there was enough interest in seeing how they all do.
What cams would you like to see tested if I were to do this and why? Any other cams/parts you'd like to see tested?
just let me know what you think!
the car/setup
5.7l LS1
5.3 heads CNCd (TEA STAGE 1)
fast 90
13/4 headers
True duals over the Axle (soon)
3200 yank
3.90 gear
Dyno
Loaded dynocom above ground. Very accurate.

Mavn, if your game, I’d love to see the results.

Hi Mavn, we like the upgrade path you've taken so far. All fairly standard and not in left field. Meaning the results you get could be duplicated by others. We like the idea of one dyno, one tuner, and your driveline combo is solid now. Also Idle KPA at 900 and idle vids would be good for our customers too. Track times and video always great with a full-weight car.
We have a call into TEA to get the valve drop numbers of a 243/799 head @ 65cc, then milled .030 and 60cc with a 2.040 valve. We'd also get their 61cc 706/862 61cc heads with bigger valves ...then milled again .030. Some of them won't be back until Wednesday the 2nd, but we should be able to get you an answer around then. Our Pro LS Stage 4 SUM-8709 was at .061/.092 with .047 piston to head and .128 intake valve drop (unmilled LS3 head with 5k miles) against a true flat top piston at a valve angle of 15 degrees. We'd think that one would require flycutting, but would like to know if (or the SUM-8708 Pro LS Stage 3) would cause any issues. Our two rectangle port cams are ground a little differently for more clearance, but we'll get into those later.
The truck swap cams were designed around their intakes, weight, converters, upgrade path, a lot of 5.3's out there, and wanting to maintain part throttle efficiency. With those different considerations, we'd want to stick with the automotive cams in this round if it comes to pass. Thanks and we'll be in contact as soon as we've heard from TEA.

Hope you hear from TEA Soon !

hmm. Also has me interested. Wonder how it works on a stock head/intake ls1 vs the ws6store hotcam. It's got quite a bit more duration. I'd be curious to know the benefits if any. Works with a stock converter too.
