750hp on stock frame? Stock type suspension?

[69restomod]

Aright guys looking for some real life experience here for the guys that run big horsepower with a stock frame and stock type suspension. When I say big horsepower my motor will be done in a few weeks and were expecting a 750 hp at the flywheel on nitrous between 550-600 and motor using a induction solutions crossbar plate with standalone fuel sustem with race fuel to make up the rest to 750hp, that's big power for me lol it's a 385 ,solid roller .690+ lift with cncd afr 210 heads that have also been hand ported, it's in a 69 shortbed c10 has an ece 4/6 drop on it with tubular trailing arms mounted in the stock location to the stock crossmember, front and rear roll bars, truck weighs 3750lbs, Frame has been boxed in a few places with tubular crossmembers, my question to you guys is how much do I need to stiffen up frame trans crossmember trailing arm crossmember etc. truck at end of last season pulled 1.7 60ft times and ran 12.60s @107 with a 400 flywheel horsepower 383 on a 28-10.50 et slick, also has a 700r4 with 3600 edge converter and a built 12 bolt with 4.11s , so if you guys have any advice on suspension setup, tires, etc. that would be great trying to get everything ready for getting the motor back in a few weeks!

Subscribed, as I am curious myself.

If you don't plan on making traction you should be ok. You'll find the weak links when you HOOK.

[Hollow65]

Try a run without the front swaybar, should get some more weight transfer. Still almost 1 whole second faster in the 60' than me. Best of luck, sounds like it should be fun.

[Ont67shortbox]

not the horsepower but the torque,is it caged?may want to rethink your trans and rear if it is not built strong enough to handle it.What about the driveshaft has it been upgraded,1350 joints etc, like someone here has already mentioned, put power to them you will find the weak link.Is this street/strip,just strip,whats your plan for the truck.

[69restomod]

I'm dropping the transmission off today to get worked on to handle the 750 hp have more details in a lil bit after I drop it off as far as parts and converter, driveshaft has been upgraded as have the u joints and rearend has been built and has a girdle as well, street/ strip mostly street with test and tunes every once in awhile.

[69restomod]

And no it doesn't have a cage

Running 740hp with stock frame rails. 15 x 14 w/ 31 x 14 Goodyear. Have been a best 60' of 1.28. Has Strange coilovers and 36" Alston ladder bars. Ran some 1.3x 60' with trailing arms.

[69restomod]

Ricksrat that is a bad ass truck! Looks like you are still running a 12 bolt? If so what all is done to your rearend? I just talked to my buddy were gonna put c clip eliminators on my 12 bolt before I get the motor and trans back, what kind of ets are you running and what is the weight of your truck?

1.28 ? That's good ! He'll the best I ever went was 1.3001. Hopefully I can hook it better next time I run WOT. Yours is impressive.

[69restomod]

I just looked at your post and saw your running a Dana 60 and what your ets are sorry I couldn't see that stuff on my phone lol is that 740 hp flywheel or at the wheels? And is that on the bottle? How do you like that nitrous plate?

Thanks Restomod. Motor Dynoed last year flywheel 740hp/704tq on pumpgas. Really like the plate and have not used both stages yet.

Thanks Regan. Yea the 1.28 surprised me was running at HMP on a Sunday night and they prep the track really good for Grudge matches. Would trade it for a 151 mph in a minute . Best I've been is 9.40@138 with old combo. Hope to see near 150 with new combo after a gear change.

[skeeterbug]

Dang yall make me sick.... Hell i always felt pretty good bout my best of 1.58 60' till now lol! Those times are Hookin n Haulin!

[69restomod]

No problem I appreciate the input! Those are some serious track times I'm hoping if I can get it to hook and nothing break that I will be in the 10s on the plate.

[71Dragtruck]

I pull 1.39's off the foot brake little bit of spin, going to try to take another 75-100lbs off it this year.


Anyway done hijacking back to the regular thread topic.

71dragtruck What is your setup for pulling those 1.30 60 fts?

71 GMC, all steel except hood, 3745lbs plus my 260, 489 pump gas BBC, dyno'd 626 with a Demond 750 carb, now running a 1000 CFM pro systems, guessing 650 to the crank plus I use 180hp jets in a Zex plate.

Turbo 350, with a 5000 stall on bottle, custom 2 piece drive shaft..

Back is 4-linked, Comp Engineering fab 9" with moser internals and case 4:30 gears, spool, 32x14 Hoosier slicks. Strange double adjustable coil overs, Willwood drag brakes

Front is a Scott's bolt in IFS with Mustang II spindles and manual rack, Afco double adjustable's coilovers and willwood hubs and brakes.

It's street legal, but this year I'm pulling the full exhaust and my front inner fender wells.

[69restomod]

Hell yea man that is a bad ass setup! Thanks for the info I appreciate it I'm hopin to have the truck done(motor, trans, and rear)in a month or so and the motor is being ran on the motor builders engine dyno so it will be tuned and ready to roll once I get it back so should have it at the track not to long after that, I will keep everybody updated on what's going down with everything.

[Wasted Income]

I have the power, but don't leave nearly as hard as you guys.

My best so far is a 1.76 60'.
3.73 gears and a 305/45/18 Mickey DR.
Trapped 122 @ 4450 race weight....so in the 650 whp ballpark at 10 lbs of boost on E85

No cage, but I boxed 90% of the frame, and added some bracing.

[69restomod]

That's a great looking frame, how do you like the 305/45 18 drag radials do they hook pretty well?

[Super73]

My best on stock trailing arms was a 1.57. That was no cage and no frame upgrades. Converter was about 1,400rpm too tight (4,500rpm, motor made peak tq at 5,700 rpm). Never got to hit that combo with the bottle out of the hole. It made 449rwhp at 7,100rpm and weighed 3,540 with me in it.

[Hollow65]

I pick my truck up next week, I'm so pumped! Been 6 weeks. Was 642hp @ 8lbs. It's now 12lbs. 610tq @ 2300rpm
Rebuilt trans, new eaton posi. Stock frame 65 c10. I'll let ya guys now if the windshield pops out with some drag radials.

[69restomod]

Made my new transmission crossmember today, gonna add a flat plate to were the trans mount mounts and gonna make some bars that go back and attach to the trailing arm crossmember.

[69restomod]

Weighs only 6 lbs compared to the stock mount that weighs 15lbs, and gives a lot more room for the 3.5 exhaust I will be running.
