1/4 mile

1995 camaro z28 6-speed
What do you guys think my car will run with this done?
Built a LT1 383 stroker
flowmaster cat back system with BBK headers and Y pipe
eagle stroker kit (pistons, H beam rods, crank, rings) comp cams cam,roller
rockers and lifters.
the crank is Forged Steel, Pistons are flat top forged aluminum 11:1 compression ratio with the heads.
I had the computer programed at FastChip in Tulsa Oklahoma
4:10 gears
The throttle body has an airfoil installed in it that decreases
turbulance

"Built LT1 383 stroker" is sort of vague.

What heads, what flow numbers?

What cam specs (besides "comp cams)?

What ratio roller rockers?

Are the BBK's 1-5/8" shorties?

Do you have a CAI?

What size throttle body?

What size injectors?

Well..... with stock injectors, you are going to be at 100% duty cycle at 425 flywheel HP, putting you at about 365rwHP. Generally, its not a good idea to go over 90%, which would limit you to about 380 HP at the flywheel = 325rwHP. With no CAI, your air intake will be choked. With the 1-5/8" BBK shorties, the exhaust will be limiting. Engine can't breathe.

Assuming you have something beyond stock heads, and something larger than an LT4 HOT cam, you might run mid-12's at 110 MPH.

Then unfortunately no one can give you an accurate estimate. Take it to the track/dyno and see how it does.

just stock heads and the lift on the cam is a .510 the guy i bought it off of said he ran it once and went a 12.7
and what if i stick a cat on it?
3inch from headers back
Also the tune called for stock injectors idk y
O and it has a functional ram air hood with ls1 type air box and K&N air filter

A lot of your time will come from if you can REALLY drive a stick. For instance, put me and a buddy of mine in the same exact 6 speed car and I guarantee that he will get the better time and mph. And I know how to drive a stick pretty well. It is just that he is a bit better at racing with a stick than I am. PS. Don't tell him I said that either lol.

If you have stock heads and a mild cam, a 383 isn't going to make much more than a stock LT1. He's lucky if he ran 12.7
