T-Rex cam ??? I have a LS6-348cid all forged with Ross pistions 3.905" with 2cc valve reliefs and 5.3 heads with 2.02" intake valves and shaved .030" I am wondering if the (T-Rex) cam will work with out any more fly cutting , right now I have a Comp E-XR 231/236-595"/600" 110lsa with no problems .I do'nt want to take the heads off if i do'nt haft to, to check pistion to valve clearance if there is any way possable

the valve reliefs should give you approx .165/.107 more P/V. if you subtract .030 for the milling and .010 for the valve that leaves .125 on the intake, you should have plenty of room.

Now, Thunder Raceing is back ordered on the T-Rex cams ,Just my luck .They said it would be the end of next week before they would have any in stock.Is there another cam out there that is close to the hp and toq.range to the T-REX .Right now i have the Comp E-XR 232/236-595/600-110 LSA ,I want to go bigger some where around the T-Rex grind

If that is the cam you want I'd wait the extra couple weeks. There really isn't anything else out there I am aware of that is the same as the Trex.
Have you considered the LG G5X4 (juggernaut)? MS3? How much bigger do you want to go? 242/248 is way up there.

I too run ross pistons with 2cc valve reliefs. I have .035 shaved off my LS1 5.7L heads and use a .040 gasket and have plenty of room for the Trex. My pistons are also .008 below the deck unlike stock or most other manufatures that come out above the deck.

hey randy i actually am in the same ball park with you right now..im building an all forged 383 and i just put in the T-Rex...i was wondering with your old cam..did you keep the timing dot-dot...i also am worried about the PtV clearance and i have diamonds 3.905 with 7cc valve reliefs...also have TEA's 1.5 5.3L heads... And do you get any heat soak like most people say with your weiand intake..

I have je pistons with a -2cc valve relief tea 5.3 stage 2 heads not milled. My cam is 242/246 with a .lift 638 on a 112 lsa. When they check the p/v clearance they told me I had plenty of room.

Yes, i put the timming marks straight up and for the intake I've not had any kind of problems with heat soak, the only thing i had problems with was the long tubs and the 02's, with the 02's being to fare down stream and was causeing my LTFT's to go into the (-) neg. or rich, makeing my computor thing the my exaust was running (cool) rich and it would lean it out so much that my car would not run or "running out of gas" ,so i had to wrap the headers to put more heat to the 02's and now my car runs perfect with my LTFT's near (0) + or -.
