Something your not realizing is the weight difference and the fact that vette trannys are geared different. 4.30's on the vette would be over kill. Not only that, i dont think they offer 4.30's for vette's.

Unless you prefer more tq down low, why not
Like I said... I had a 236/239 heads/cam 346 before and I didn't like all of the racket.

Guess I'm growing up

yea, i realized i put 4.30s instead of 4.10s after i wrote that response. i dunno how sluggish that cam would be down low in his vette but i would still think to do 4.10s in it. even though they are geared differently i don't think that would be over kill with the 6 speed.

I talked with TR and they said you do not need to flycut the pistons. I think I will be fine though because I can always use a little spray for that loss of down low.

changing gears is a little more expensive in the vette ? 4.10 will tear up axle shafts quicker , thats part of the game though buy one thing and 5 other things have to be done . Good Luck

You guys need to remember, the Z06 has gearing equivilant to 3.90's from the factory. Installing a 4.10 rear end would be wayy to much gear for that car.

If you are not gonna get some gears, I would suggest NOT running a Trex. You WILL regret it if you put the Trex in and still have the stock gears.

I am running a cam that isnt quite as big as the Trex and I would hate to know how it would drive with the stock gears..

Did you not read the post above?
The z06 has different gearing in the tranny(more aggressive) is lighter AND has more compression. The guy would be OKAY with stock gearing but even better with 3.90's. 4.10's in a z06 with its gearing and light weight = have fun trying to get traction.

Have you ever drove a M6 car with a Trex or something close to a Trex? If not, you wouldnt understand what I am talking about...

I guess your still not quite getting it. His VETTE not FBODY, has much differnet gearing and weighs quite a bit less. Between the differnece in gearing, weight and a good tune, the T-Rex wouldnt be all that bad in his VETTE. Obviously some 3.90s would help low end, but they are not needed for it to be tolerable to drive.

I've driven Mcduffys X4 cammed car. I also drove my car with a cam thats rather...good sized(AZPS03) and CNC'd ls6 heads WITH STOCK GEARING and it pulled like a freight train, wasn't doggy at all. So I have an idea as to what you're saying, but we aren't talking about an F-body. You're wrong man, let it go
