Well, any of you TREx guys running your stocker gears? I know it can be done. I just drive my SS on nice days and to car meets, road trips. Will also be getting ported LS6 heads, LS6 intake, LT's and ORY, 7.400 pushrods and a PRC spring kit.

I don't have this cam but a buddy of mine had that in his 02 SS for a while before he built a 408 and he traded in his 4.10s for 4.30s in his car after he put the Trex in.

Just about anything can be done. TR recommends numerically higher gears for a reason though. After the newness wears off, you'll be figuring out how to put gears in it. With the new power, it won't be a 10 bolt either. Plan on doing it right from the start or you'll end up with a car that's not fun to drive any more.

I DD my Trex with 3.42s and a 10 bolt. Only bucks in lower gears, I can cruise @ 1200 RPM in 5th or 6th

Of course you CAN use 3.42's with the T-Rex, but its not a good choice. I would atleast go with 4.10's. 3.42's don't make sense like running a stock exhaust with that cam wouldn't make any sense. Everything else on the car is a decent set up for the T-Rex, why not finish the package?

Well, I have a Magnaflow catback, as well. I have been thinking of getting an F10 and getting my heads milled to about a 10.8:1 c/r. I don't know how much milling I would need to do. I need to find that damn calculator and figure this out.

Driving the TRex is absolutely possible with the stock 3.42 gears. Just don't be disappointed if you take it to the track and you don't get the times you think you should get. My wife has the TRex in her car with the stock 3.42 gears and we can drive it without a problem. We are planning on a Ford 9" with some 3.90 gears within the year though so we can take it to the track and and have some fun. If the 3.90's don't net us where we want to be then we will just get some 4.56's put in.

Nah, I won't be going to the track much. Would like to have it for some highway fun though, thats about it, it isn't my daily driver.

I would suggest looking into somthing a bit smaller and better for dd and stock gears..

So would I. I had the T-ReX for a couple of years and used the stock gears for one of those two years. It was cool for a few months, but eventually it got old. That cam is huge for a street car. People will tell you it can be daily-driven, and while that may be true, I can almost guarantee it isn't going to be as enjoyable a daily-driver as you want it to be.

I switched to a smaller cam about a year ago and I'm really glad I did. The T-ReX is a great cam that does what it was designed to do, but I'm confident it wasn't designed with daily-drivers in mind.

Just my $.02 having been there and done that.
