Any H/C numbers with the TRex??
Any H/C numbers with the TRex?? I am getting a set of Patriot Stage 2 5.3 liter heads and am wanting to go with a TRex. I had planned on running the MS3 so I wouldn't have to flycut the pistons, but I would like to see some numbers so I can decide if the extra work is worth it. Thanks
With heads it isnt worth using that cam. The grind is intended more for the manorisms of a stock intake port. IMO, the G5X3 or a custom grind will net more power than either of the cams listed above.

SlickVert put down 467 @ 6500 with ET heads, 90/90, and 12 bolt w/ 4.56 gears in a M6.
With smaller gears it would have put down around 480. Pretty impressive if you ask me. I think the guys saying the T-Rex won't work well with aftermarket heads are underestimating it a little.

The well chosen valve events that make the T-Rex work so well with stock heads are also the why the T-Rex is a superior cam for ported heads. Too often, cams of this size go too wide in the LSA, giving crappy dynamic compression and too late of an intake valve closing point...not the T-Rex. The T-Rex has a 109-110LSA which closes the intake valve earlier and opens the exhaust valve later. This helps pump up the dynamic compression while keeping the intake valve closing point in a window that works well with the LS6 or FAST intake. Look at other dynos of wider LSA cams like the MS3 or HPE S cam. They make great top-end but are lacking in the mid-range torque department. Why? Poor dynamic compression relative to the T-Rex. The T-Rex has violent mid-range torque and very strong top end power. Why? Better chosen valve events which work even better with ported heads than they do with stock heads.

Does anyone on this board have a h/c pkg with a trex making 470+ hp? Anyone?
When there are cam only trex cammed cars making 440-450 rwhp through 12 bolts I would assume that if it was such a great cam for ported heads someone must have picked up atleast 20- 30 hp. Maby they have and I just missed all the posts. I also think that it is a killer for cam only but on the cars Ive seen that have added heads the numbers never added up.

Most of the big h&c numbers you are seeing with smaller cams have small gears or stock 3.42's and a 10 bolt (non track cars). Most of the T-Rex cars are track cars with power robbing drivetrain and large gears. Like I said earlier if SlickVert had a 10 bolt and 3.42 gears he would be over 480, but that's not real track friendly now is it?
Well I am going to be a non-track car. What cam should I go with for my 5.3 stage 2 heads?
I would really like the Trex but am unsure on how much it'd cost a mechanic to install it (with the flycutting, etc etc). Anybody know? I'd really like to go this route so I can have a lot of midrange torque with a ton of power up top. I don't plan on going higher then 3.73 gears and I have a brand new 10 bolt that I'll be getting a girdle and new axles for.

If this is not going to be a track car, spare yourself the agony of living with a top-end oriented cam like the MS3 or T-Rex and get something milder. For strong area under the curve and great top end power, my cam is an an absolute joy to daily-drive and street race. Specs in signature. When in doubt, go a little smaller.

I know of somebody that did 610rwhp with TEA heads/ X3 and a 150 TNT.
Then again theres Termin8r's car that does 640rwhp with stock heads and a 200 shot with a MS3. You wont be dissapointed with the MS3/spray combo.
My cam is right in between the two and ****** rips on the spray.
