No, I am serious. I know that it is a huge *** cam. And is not recommended for street use. But I am also aware that if you drive normal but still want to have a absolutely bad *** cam for the track this cam is it. Now what I am asking is when you do not have your foot glued to the floorboard what kind of mileage does this thing get. 8, 15, 40 come on I know alot of you guys have this cam. I just want to know what I will be looking at. I dont need any emissions, I dont have to have anything restrictive on the truck.

Guys it's a simple question. I will never understand why people post a reply to someones question with crap and no answers.
To answer your question: A person I know has a custom made cam that is SO close to the specs of the t-rex, it may as well be the t-rex. Anyway, normal driving, a-4, 4k stall, 4:10 gears he gets around 18-20mpg. Spirited driving, it's more llike 9-12 or so. Hope this helps.

Dude..........a lot more goes into gas mileage than the size of a cam. Gas mileage in a Camaro with a T-Rex is a lot different than gas mileage in a 1957 all-steel truck with a T-Rex. Hence why somebody asked for more info. It's NOT a simple question.

Ok to answer those questions. It will be tuned by Wait4me performance on this board. He is also gonna be reprogramming the ECU. The original weight of the truck was 4500 pounds. That was with the original 3/4 ton long wheel base frame, The original monster truck wheels and that heavy *** rearend it had. The truck has now lost the straight 6, the long wheel base frame and is now rolling on a swb frame and a IRS from the C5. I will show some pics. the gears I have been told are the 2.73's that the C5's come with. I know that there is a optional 3.15's that they had but I didn't want to tear into that yet. So I am still assuming on the 2.73's Also the truck should weigh around 500 pounds less. Took alot of excess weight off of it.
here is a link to the pics.

with a 4000lb truck packin 2.73 gears you will ABSOLUTLY HATE that cam, you need ATLEAST 3.73 and a 4000 stall in a truck like that, i drove it in a 3600lb car with 3.42 and 4.10 and 4.56 and the 3.42's are tough with a clutch if you not a good driver, with a auto that is gunna be the biggest pig ever with a stock converter and the gears you have, im sure it will pull like a scared **** from a roll on the interstate but leaving a stoplight will be like driving a geo metro

I am building my dream truck. This is the vehicle I learn to drive when I first got my liscense. And I have wanted one ever since. But I know that I will need a stall spped converter and a set of gears. I am not 100 percent sold on this cam. I just thought I would ask a few questions. I don't know what route I am going to go yet. Just asking a few questions and doing some research.

that's pretty cool you still have that truck. My first car was a '67 Camaro RS that I sold to some douche-bag in Missouri and for the rest of my life I'm always going to regret doing it. I was tired of spending money to keep it running so I let it go. It's probably wrapped around a pole right now.

IS this a daily driver, occasional driver, or a track car? If its either of the first 2 then a trex isnt the cam you want. Look at more of what people call a small cam for street use. My 224/224 out pulls a 230/232 all the way to 5800 rpms but after that it looses by 10hp at the peak but has more tq. Its the combination of things that will make your power not just a big *** cam. I'd love to run a trex but it makes no sense in a street car unless your going to drive around at 5500 to 6000 rpms all day and thats just stupid but you have an a4 wich makes it even worse. smokin01ta nailed it. Look at 220-227 range

Theres one in every crowd. Its not a dd cam, but that doesnt mean someone wont live with it just to say they have it. I'm sure it drives fine but having a powerband in a useable rpm range goes a lot further for a DD street car than having hp it at 7000 rpms. The trex doesnt even start to develop power until 4k rpms. In a street car your getting your *** kicked from one stop to the next by a pos rice box while your trying to get the rpms up to access the power. Then traction is another thing if you have to stall so high to get the power. If all you want to do is "frumroll" on the highway then ok get the trex. And I'm a trex fan, but his is my dd not a drag queen.

As well are you. I'm sure your car drives fine. The whole idea of a caming the car is to make it quicker or faster. Not to say I have a big cam. Call racing immature if you want but why in the hell would you cam a car or try to improve its power if your not going to use it. To each his own. This person is looking for performance not just a cam name so he's getting good advice. I know I'm dising you a bit, but its not really my intention. My intention was to provide info that a properly cammed car is a lot faster than a biggest cam I can find car, depending on your needs. This is for a 98 ls1 with an A4 going into a slightly heavier than fbody vehicle. trex isnt a good choice here. He wants torque to develop a lot faster in the rpm cycle. Yes he could get 410's and it would help, but it still wouldnt be ideal. Your right this is my opinion but its backed by more than one person as well as the trex king.

And each and everyone of your opinions are appreciated. I am not just looking for a Big *** cam. I am looking for a cam that will make wake the LS1 up. If this cam is too big for the normal everyday driving then that is fine. I am up for suggestions. I want something that has a lumpy idle to it but can still be driven like a sunday driver. I don't want to have to keep my foot glued to the floor to get it to make any kind of power. I am looking for something that would make good power through the whole powerband but still be able to throw down at the track on the 1 day in a month or so that I would like to go to the track. Do you guys think it would be possible to get say around 450 with a cam and minor bolt ons? I mean at the motor of course.

450 with cam + bolt ons is a really really long shot. Jason made 450+ hp with his Trex + boltons, but that is an exception rather than a rule. I haven't heard of any other car duplicating the feat, especially with "minor bolt ons".
