What do you think my truck will run
 

What do you think my truck will run in the quarter it is an 86 gmc sierra classic with a 415 horse 465 torque 388 stroker. it has 3.7.3 gears Just tell me what you think :bowtie: :gmc: :metal:

14.5-15.5, My guess would be.

Mid to low 13's. Depending on traction.

im thinking that with the best traction, at sea leve, maybe 14.40s to 14.20s

I'm gonig with 13's as well. Depends on weight..tires...you got enough power LOL. You got any fiberglass parts? Every lil bit of weight helps haha. But yea i say somehwre in the 13's.

Are those projected numbers or actual Dyno numbers, that will make the difference.

dyno
 

those numbers are dynoed numbers and no it is totally stock in the body department and the only real thin i have added is the engine and the traction bars the rearend is also a poistrac so that will have a little to do with it :bowtie: :gmc:

I say it will run mid 13's . Depending on the power you can get to the ground and if it is a posi rearend wich will help get the power to the ground equally

High 13's - low 14's But tranny, has alot to do with it. What size converter do you have? And is that a motor dyno or rear wheel dyno?

It is a motor Dyno and the tranny has a shift kit and corvette servo in it

So its prolly like 360 hp and 410 ftlbs at the wheels. So yeah prolly low 14's high 13's. What trans does it have?

I would say 12's...a friend of mine put a ZZ4 into a 65 chevy SWB, and he put down a Nitrous-Fed LT1 Camaro! He never ran it at the track, because the thing simply COULD NOT hook.

No way 12's without nitrous. That motor running "all motor" will go low 14's high 13's now that i know its flywhell hp and not rwhp. Yea the pois will help and so will the 3.73's for sure but...theres no way that tuck will hit 12's unless its got a shot on it lol. ((no offence to the owner)) Sounds like a SWEET! truck. :) You better run it soon i wnna see some times man! :)

the truck will never have NOS and i run it this friday so you will have times soon i dont see it hittin 12's either im prayin for 13's

I gotta whole new body and i got a 4-6 drop kit for it the drop is with upper and lower control arms and a flip kit, then im having the frame, the rearend, the leaf springs, the calipers all powdercoated. Stainless steel brake lines, four link rear suspenion, And it is going to be Reallllllllllllly dark green almost blackit will also have the conversion kit for the headlights then it will have 4.10 rear geard and 13's in the back

low to mid 14's is what i'm guessing

I'ma make 2 guesses:

1. 13.96
2. 14.29

Pipe dreams!
 

Good luck with your race against the clock! I think any faster than 14 sec. would be a pipe dream,by all means post a copy of your times and prove me wrong. Burn lots of rubber and run aviation fuel (jet fuel) for the best run. I hope you have good slicks,so you do not spin on launch. RUN HARD AND FAST! :burnout:

Probably about high to mid 14's depending on traction and skills.
BTW: You need about 500hp to get to the 12's in a pickup.

Maybe I missed it in the posts but are you going run it or what? I want to know dangit ha ha. I say high 13's. Good luck

On radials it will do somthing in the 14's, with slicks and fantastic traction you'll get to 13.7 at best, to go lower needs more power.

I can't wait to see these times......tell me about the flip-kit, rear leafs and four link? That should really hook. We want the track slips scanned it so we can see all the details:)

Seeing the amount of variance in the times everyone is saying has got me wondering....Who thinks my time is BS? 14.51 @ 91.01 with about 300 HP or so. Stock 350 8.5:1 with a 268H Comp cam. I'm not trying to start anything, but seeing that this guy says he has 415 HP and all he can get is high 13 seems funny. Any comments?

I have a comment: I love your avatar!

When I had my 383/450hp my best time was a 14.20 but keep in mind I had a 3.42posi and really ****ty pepboys 275/60/15 tires. Anyone who's ever actually gone to the track and ran their truck knows that all the power in the world doesn't equal low times. Your time represents an excellent run and I guess pretty decent 60ft times. I have to question sub 14 second times (SBC) without the use of either slicks or some type of traction device. I wish we could all meet at Atco raceway (NJ) tonight and find out what's working for everyone.

Yeah my 60' on that run was a 2.07. It just came off the line good. I want to get some 26" ET Streets and see how low I can get. I really need to tune my carb, as it is a Edel 1406 with elec choke that is calibrated for mileage. There may be a tenth or 2 in that.

Another big factor is altitude. Look at Cochino's time. He has a ZZ4 motor and cannot get into the 14's. I think he would be in the low 14 or high 13's if he would run it down here.
