I just bought a 87 z28 with a 430 horse power 70 or 71 350 in it the motor has a cam 202 heads 650 holley double pump carb and for the trans i have a turbo 350 backed up by a 2000 stall and a stage 2 shift kit . my rear gears are 411 and it is a 12 bolt posi unit. ?what 1/4 miles times should i get with my set up with a good launch??? any guess :huh:just wondering

I imagine with a good launch it's in the area of a 12.2...

whats the cam specs? what pistons? what comp ratio? if the motor isnt matched it could be a terd but if everything is put together right and matches she could fly:burnout:

the pistons are 11to1 dome pistons with 202 heads a holley 650 double pump carb . i believe the cam is the 290 cam ''lopey idle'' with a 2000 stall converter backed up with a 12 bolt rear end with 411 gears. the motor had over 325 horse power before all the work was done on it. I was just looking to see what it would run in the quarter mile i know when i tap on the gass it wants to lift the front end . so i know the power is their. what size tires can i fit on the back for traction? the guy i bought the car from said the motor had over 430 horsepower. which isnt hard to get with the 70 and 71 350 4 bolts. ? let me know what u think:D
I know iam gonna get bad gas mileage but who cares. iam driving one bad *** third gen lol.

if its the comp 290 cam or is it 292 i cant remember but anyway that motor should fly im thinking anywhere from 11.90 to 12.20:thumbsup:

You prolly got crap heads, and that stall is just about at the stock level...

Mid to high 13s but it's impossible to guess really...

:yup: that converter is stalled way to low for your combo. Maybe in the 3000-3500 would be much better. Let us know what time you run at the track
