Well I saw this cam in action on a ls1. Contacted Thunder and found out I can put this in my 5.3 liter with heavy amount of tuning. A guy had this installed on his trans am with a 4000 stall. He ran a 12.20 with the stall. Added the T-Rex cam and ran a 10.65-10.44. Just With a cam and stock heads. Wow screw a supercharger. Anyway contacted Thunder and they claim with the T-rex and a 3800 stall My truck should easily run in the 12's. My truck runs a 14.78 right now without a stall. Check out the Ls1 cam at Thunder racing.

T-Rex cam specs are 236-242 duration 608-610 lift. 110 lsa. 3600-6800 rpm. Over 85 horsepower gain AT THE WHEELS check it out. Later guys. Oh and One more thing you should know. This is not a daily driver. The cam is not very streetably. Idle has to be set at 1200 rpm. Later, Jared

 

DO IT!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!OMG that would be nuts

 

damn dude thats goin all out, alot of guys are scared to put that in there ls1 let alone a 5.3 Your streetability will be **** but **** it if its not your daily Id love to see it. I just wonder if the heads on the trucks could flow enough or even if theres enough displacement to take advantage of it. I guess well find out. Id bump that idle up to around 2k though you wont have any power below that with the cam and stall I doubt it would even move at 1200 rpm.

 

Get a fat stall! Guy here in town has that cam in his TA. It is soo funny to hear him try to take okk from a roll. I think he has like a SS3600 or something.

 

i like the trex

 

Do it! set new standards for the trucks!

If your tuning is done perfectly, I think it will be ok.

 

i thought about putting this cam in my 6.0 and everyone said it was too much cam for a heavy truck i say do it. i think it will run HARD.

 

Do it!! I'll help ya with tuning all I can.

You got HPTuners ?

 

man that would be sick. i was told that the cams i have and am running were big but that is way big. last cam-224-228-581-588-114+4. new cam 224-224-581-581-112+4. but that is huge. go for it. i wanna sound clip of that one.
