Default Need help on cam only decision 01 SS m6

So I have an 01 SS m6 Camaro 57k miles
currently have :
1-7/8 TSP LT headers
TSP y-pipe
SLP LM1 (soon to be magnaflow prob)
4.10 gears but just blew my 10 bolt so new setup will be ford 9" with 4.57 gears
255/50/16 MT ET Street
SSRA ram air
SLP Lid
SLP Smooth bellow
160 Thermo
dyno tune
Put down 349 WHP 359 WTQ on loaded dyno

I am torn between the TSP MS4 cam, the Tick Performance Polluter stage 3 V2 or the T-rex cam

My tuner said he can tune all 3 no problem but he prefers T-rex

who makes T-rex cams now since they seem readily available yet thunder racing seems to no longer have a website?

obviously I will be doing supporting valve train mods (pushrods,valve springs, rockers etc

First hand input is definitely appreciated thanks!

If you order the Polluter camshaft from us right now (or any of our shelf cams for that matter) you can get 10% off by entering the coupon code Facebook10 at checkout.

Of course this doesn't apply to the complete package, but if you buy everything individually rather than as a package you'll still save a few bucks.

Let me know if there is anything we can do to help!

Out of those three choices, I would pick the T-rex cam.

Without looking at profile cards, I can only assume that lower lift equates to more mild lobe profiles, which is a huge determining factor for me.

Also, the T-rex has the most exhaust duration, as well as a larger exhaust bias. Without looking at the actual valve events, I would imagine that this cam will carry power further up the rpm range.

Both of these assumptions could be totally wrong, though, given that I didn't compare actual lobe profiles, or the actual valve events, just basing my pick on easily and quickly obtained advertised cam specs.

If you are leaning towards the Trex cam call Geoff at EPS since he is the one who designed it (or so I've read numerous times) and let him spec you something similar but better.

Well if it's any consolation my buddy has a setup practically almost the same as yours, but with the trex cam, and runs 11.6 @ 119. Minus the lighter rims the car is full weight. It made 420 rwhp as well

Why not get a vendor to optimize a cam for your set up. Custom cams don't run to much more than shelf grinds. Just a thought.

I should be ok with a shelf cam though since I have a pretty typical setup.

also when I am in there I am going to do my oil pump and timing chain setup any preferences on those brands?

Ported/blueprinted GM ls6 oil pump seems to be a popular choice. As is the GM ls2 timing chain. No need for anything fancy.

The point was Thunder Racing went out of business so it is no longer a "shelf" grind anyway, but the guy who designed most of their cams now runs Engine Power Systems.

So you could even get something virtually identical to the TRex but on his better lobes which will then be cut on a Cam Motion core (as opposed to the inferior Comp cores used by Thunder Racing).

You will end up with a better overall product even if the advertised specs are virtually the same.

I would get something that wont have P2V contact with the 243's you're going to be eyeing a few months later.

Of the 3, the polluter is the only one I have experience with. Great cam. I bought the ported pump and chain as a package through Tick. I swapped to an underdrive pulley and water pump at the same time.

Could be leftover inventory or could be they are just still selling the cam by ordering a cam through Comp Cams to the old specs. If I recall it was just a Comp XER lobed cam. Another reason Geoff can probably get you something better since he has his own lobe profile now which makes power but is easier on the valves and springs.

I had heard a while back Thunder Racing was re-opening but considering the number of threads on here about people getting screwed over as they were going out of business I would stay far away even if they are back in business.

Stock LS1 with exhaust and 4.57gears..... no upgraded rod bolts? I think you will run out of safe rpms with 4.57s and strong camshaft that makes power up top.
