One Question!
 
What kind of power will it take to run 11's in a LWB 82 with stock suspension?!

Re: One Question!
 
To the wheels I mean.... Not flywheel...

No jokes but your gonna have a hard time hittin 11's with a stock rear. About 420 to 450 at the wheels will dip into the 11's with a decent rear suspension. If you wanna have fun at the track concentrate on 60ft times. Its all shiftin after that. A good 60fter will always post good et's in a good state of tune.

K, so without going 4 link, what would you recommend? I'm having a 650hp 496 built right now, and also need to beat a 2011 Smelby Rustang!

I dont know what your abilities are but I'd say box as much of the frame as you can. Shoot a pic of the rear suspension so I can see the condition. Being leaf spring I'd say add slappers and tune them so that you can slide two quarters between the pad and spring eye. DOT track tires, replace rubber, shift kit set on kill, adequate trans cooler, adequate fuel supply, adequate BRAKES!!! You can build a junker to run an 11 but don't plan on it making too many passes. Get it to hook and leave and make improvements from there. Get outta the hole then get down the track. Don't break it untill you hit 11.99. Know when to lift to save money. AND REMEMBER!!! Drag Cars are not remote control!! It takes more than desire to drive to the end!!

Detune that thumper and tune up as the truck catches up!

Well the stock suspension is old... Never hauled anything, but 120000 miles on it.... I know I gotta do something, just looking for the budget route on a vehicle that will be daily driven, but will be abused too...

Re: One Question!
 
And what kinda diff would u recommend? The stock pos has to go... Want something that will eventually hold up to traction... Will a 12 bolt do, or should I look at a 9" or something?

Re: One Question!
 
Freshen up the rear suspension (may need new springs!?) wherever possible. Plan on big sticky tires and keep the motor one step above the rear suspension. Get some timeslips and ask more questions.

Re: One Question!
 
Leafs, traction bars, tubbed, and a bada$$ tire... Gotcha!!

A 9'" is the poor mans quick change but its not neccessary. What housing do you have? It should have the potential to hold the power.

69GMC910 08-06-2011 12:04 AM

Re: One Question!
 
I think its an 8.5???? 3.08 open rear end...

I think these trucks can handle a 305 or 315 DOT so you shouldn't need more and more costs more. Remember 9" tires can carry the front wheels on a stock style suspension.

Was a cheapo truck off the lot in 82... Only option was the 350 I think!!!

Re: One Question!
 
Verify that and if you prove what you thought find a bigger housing and put in it only what you need. Don't forget the rest. Protect the trans and make sure you can stop it. Again stiffen the frame and I'm sure someone with Dragtruck experience would have something to say about ballast. Your better starting off with a LWB too!

Re: One Question!
 
But the look is so much more appealing!!! And my buddy will weld the tubs in for a bottle!! Priced out 15x12 or 15x14 rally's at 240 a piece... Not too shabby!

I just know the diff is the most neglected art of a high hp vehicle, and want to have something that lasts...

Two ther things: Lower it to help transfer and always build to be safe. Google "instant center" and read it to se if that will help you.

Re: One Question!
 
I always say speed before money but everyone gets a closer look on the return road and in the pits. In my mind I like to be the one who doesn't look like it could go that fast! Sleeper?

69GMC910 08-06-2011 12:24 AM

Re: One Question!
 
I am trying to stay as stock appearing as possible. As much as I likenpeoplea customization, I prefer things to look "as sold"... I hope to have the drivetrain done by late september, so I'll be on here lits in the coming weeks!! Thank you for your help/advice!

Ive ran 12.19s with a mild 406
On leafs. Cal tracs and drag radial. The motor is the easy part.
making it hook is the trick

@BMRDOC, why do u say starting with a LWB is the best route?

Re: One Question!
 
Its all about weight transfer. How long is a Top Fuel car? Plus the smaller wheelbase and track width the more unstable it is at speed, all else being equal.

Re: One Question!
 
Never thought about the speed/length thing!! Good call!
