what is the stock E/T for Iroc with 350 TPI ?? with 2.77's or higher???

 

Like 14.4-14.5. The better geared cars run very low 14's.

 

the previous owner of my car got it to run a 14.2 with K&N as only mod. And my car has the 3.27's. In proper tune the 2.77 geared cars should run mid to high 14's sometimes better. The overall tune of the car usually comes into play more than anything.

 

14.8 or so. If you cant get it into the 14's then their is a problem. The 3.27 gears cars were good for around 14.4s.

 

When my car was stock with a K&N and flowmaster muffler as the only bolt ons, it ran a 14.49 with 130k miles. It has 3.23 gears.

 

Depends on if you are on the coast or inland. Everyone talks about low 14's...ya right not stock around here. In the midwest you are lucky to hit high 14's!! With no mods whatsoever my car ran 15.00 and that was it. I wish I lived on the coast, hell I would pick up @ least .5!!
