1/4 mile time/horsepower/weight estimates?
1/4 mile time/horsepower/weight estimates?
hi i have looked around a bit but having a hard time finding numbers i can believe or relate too, the strip here is closed until next summer and i just got my new motor broke in so im curious to what it 'could run' ( in a perfect world where my t5 wont explode)
car is a 83 z28 5spd with 3.08s in back, aluminum centerlines, t top with manual windows, basic stereo, pretty basic interior( aproximate my weight?)
motor is a 357(.040 350) with comp 282 roller cam/ howards lifters, eagle crank and rods,peed pro pistons,9.8:1 compression,summit 200/64cc aluminum heads loaded with good valvetrain(supposed to be a chinese brodix ik200?) summit 750 vac sec carb on a summit dual plane, and 305 manifolds with about 3' of open 2'1/4" pipe (for now, headers and a real exhaust next year) standard dizzy @ 8btdc , 36 degrees total (i think, my machinist set it i broke my light)
all i know for sure is that she is no slouch, and on my 500 mile trip back home while i was breaking in the motor i got 23mpg
if anyone can help me guess my 1/4 mile time, crank/wheel horsepower and curb weight of this car it would be greatly appreciated, thanks

Re: 1/4 mile time/horsepower/weight estimates?
oh and i dont know if it matters much but the motor has a 327 balancer on it, and a 305 flywheel, with a mcleod super streetpro organic/ceramic clutch, and the whole works is sittin on solid mounts

Weight? Put the car on a scale with you in it.
HP/torque? Put the car on a dyno.
ET? Give me those two results and I'll give you an estimated ET providing you can get it down the track without the T5 failing.

closest wheel dyno is 350 miles away, i dont know where any trucker scales or anything is around here, if the dyno was closer i wouldnt have posted this, if the track was open i wouldnt have posted either, but neither of those things are around or open, cant anyone even give an estimate? i dont know where to begin guessing my weight at, my 85 s/e weighed in at 3650 with me in it, but i had a 'bit' of extra weight in it

Without knowing important data, a guess is 12-14 seconds.

Well i guess im just guna have to wait, theres only 2 strips, and 1 dyno in my state,just figured with all the third gen owners someone would have an idea what a t top 5 speed aluminum head car would weigh, and maybe i thought someone might have built a fairly similar motor for a reference point, 12-14 seconds pretty broad..

I would say 13-13.5 I had a similar set up with 373s but double hump heads and went 13.65 @103
