It doesn't really work like that. Your engine with 3.42 gears is not reving as fast as it would with 4.10s out back. It will take you longer to reach your power band
Thanks, but too dang hot. Probably be slower even with the tune lol...need to work on the vette and get it ready for Drag n Brag at TMS
Actually it does and I've got proof with my 10 second vette that I've swapped from 3.42 to 4.10s. The reason why 4.56s are faster is because you don't make any extra shifts with them than the 4.10s, cancelling out the gains from torque multiplication.
Thanks, it's a Performance shop owned by Steve and Loyd located off 287 in Haslet. Matt is the tuner and he's running a special for $350 this month.
Your talking about a car that's 1700lbs lighter going to 3.42. There are guys on here who have done the 3.42 swap and their TBSS is a TURD off the line now. You would be playing catchup the whole way down the track in a 5,000lb brick with horrible drag and weight.
1590 lbs to be exact:biggrin2: I hear what you're saying, but I have not found any concrete evidence to prove me other wise. A shift takes ~.3 of a second, I've hopefully picked up that much in a tune from power and the quicker shift speed and longer shift extension counters the slower 60'. It's a theory at this point and I know the thing will be slower with 3.42 gears than 4.10s, but I didn't get it to drag race
I would not go 3.42. Try 3.73 if you must1590 lbs to be exact:biggrin2: I hear what you're saying, but I have not found any concrete evidence to prove me other wise.

or save the fricken 2000$ for the gear swap and itll pay for a frickin cam with cam kit and to have it installed!
3.73 isn't worth the swap. Run a gear calculator on 3.42s and a 6800rpm shift point and you'll see why the 3.42s make sense with the 275/45R20. http://www.f-body.org/gears/
Gears cost $230, not $2000. Granted I will have to run through a few tanks to pay for them, but I will be able to bury the speedo instead of just kissing 140...headers will go on to help make up any lowend loss. Right now it fish tails around every corner in first even with over size tires, in 100* heat with the a/c on. Heck I've had it step out at 60mph in 2nd on a sweeper, handles well for a 2.5 ton SUV!
