need help lowering et's
I was dissapointed in the times I run last Saturday.....only pulled a 14.1 at 96 with a 1.9 60 ft..... my car has full exhaust built tranny with shift kit and slightly bigger stall, Holley stealth ram intake, ported 083 heads, and 275/40/17 tires and my car weighs 3560 pounds with me in it....I was really hoping for a high 13

More power, less weight. LOL, that is what makes my cars run in a straight line.

Get rid of the 17" rims and use some 15's to give the tires a bit more sidewall to work with. Put some sticky tires on the rims.
Find some way to take at least 200 pounds out of the car. The less weight you need to move, the faster you can go with the same amount of power.

What was the weather like? Mississippi this time of the year is not very friendly to low ET's! Come fall, you may be well into the 13's.
