Re: 500hp

Make sure that you got the drivetrain to back it up, including brakes.

Re: 500hp

With a fully locked 4.10 gearset it is going to feel dangerous. I am hoping you mean a differential and not a spool. With that much power, you will be spinning the tires off with the stock leaf setup.

As for how it feels, that would be hard to describe, maybe over powered?

Re: 500hp

500 hp in a leaf spring truck is pretty harsh -- if it ever attempted to hook, the axle wrap would be severe and the tires would spin for days. That new Viper motored Dodge - the SRT-10 -- is only good for low 14's, high 13's in the 1/4 because of things like this

Most people with engines like that in these trucks just use them for cruising and rarely pour the coals to it-- probably would be a wise idea to hold off on the spray until you are out of the hole too--- but there is a company that makes custom slapper bars for these that tuck out of the way where you cant see them from the side, and work well

I am assuming 500 corrected hp though, --- 500 uncorrected at the crank is more like 425 at the rear wheels, and that is a bit more "manageable". You didnt mention it, but is this a small block or a big block? There is a huge difference in torque too, between the two that will mean more in a seat-of-the-pants measurement than the net hp reading (big blocks feel faster, even if they're not--- i dont know the science behind that, but its true)

Re: 500hp

If it is locked it will definitly have wheel hop.

If you really want it to hook, you need these:

question i have,

how would these caltracs compare to a decently setup 4-link and coilovers?

the caltracs are MUCH cheaper and i had totally forgot about them until you posted them. i want to go with a 4link setup next year, but if the caltracs will hookup just as well and save me money...

with 4 links / ladder bars and coil-overs, you just about have infinite adjustability, but with the Caltracs it's very limited. For a mean Streeter I would go with the Caltracs everytime. these are a bolt-on installation and thats a h3ll of a lot easier/cheaper than 4link/ladder set-ups!

What's your combo? 500HP at the FW is often discussed, seldom seen

i don't know... I don't feel like pulling two spark plug wires to find out

seriuosly (did I spell that right?) with these trucks and speed... it's all about traction, trust me... been there, broke that. Without the right suspension, all your efforts will go up in smoke (tire smoke)

Re: 500hp

and like CaptKaos said...

Caltracs are worth their weight in gold! I know of several cars and a couple of trucks that the only suspension mod was a set of Caltracs and some good shocks and are getting 1.50's at the 60 ft mark.

Re: 500hp

You can get sub 2.0 60ft with these easily. They are limited in adjustability, but they work. We are putting a set on my brother 2000 Silverado that is turbo'd.

Re: 500hp

here is the set up. first off i have a fully boxed frame with a custom made four link and coil overs. i have a fully built ford 9" rear with a lock rite locker and 4:10 gears. the rear is narrowed with 33 spline moser axels. its going to have a fully built t56 tranny with aluminum fly wheel and driveline.

now in front of all that is a fully built 10.6:1 small block 388 stroker. everything is blueprinted and port matched. forged internals

when the project is all done i should be seeing about 500-520 hp at the crank. then on trck days im going to put 100hp nos shot in it.

did i mention its tubbed and im running the mickey thompson s/r sportsman radials for the street.
29x15x20 on coys 20x14 in the rear and 18x8 up front

impressive HP for a small block you must have mucho denero tied up in that mighty mouse

If it hooks well, I would say low 12's to mid 11's... 10's in these trucks are pretty hard to achieve with a street/strip set-up

planning on running a different tire at the strip?

let me know how those radials work out, my sportsman pros are shyte for cruisin...

and like that guy said....

Re: 500hp

Sounds like an awesome setup! Pics would be good As for how 500 hp feels...let my brother finish breaking in the engine on his supercharged Shelby GT and I'll let you know.

Cal-tracs on my '73...can't wait to try them out. The install is super easy, and they have an awesome street/strip rep for their performance. Very well built too.

Re: 500hp

i will try and get some pics soon, its all in parts now, but i will see what i can do.

how does $4800 sound for the whole motor. not bad i think. i was hoping to hit the 11's on this set up, but who knows.

yeah i will be running slicks at the track prolly a 29x16x15 or something like that. im hoping i will be able to get tire spin at close to 50mph, im gonna have to use some crappy tires for awhile to get the burnouts out of my system. i dont want to burn out $400's per tire

If you can put 500 HP at the crank for $4800.00, then you are pretty good. Hopefully you are doing the assembly and the price that you quote are the parts prices. The reason I state this, that type of power needs a good quality parts list, for longevity. I agree with others that the motor will tear everything else up trying to do what you want it to. A good tranny, driveline and axle setup is paramount to your making the power and getting it to the road.

I don't have 500 HP, but my 84 SWB with a 385 stroker motor is pushing about 400 at the crank and it can be hard on the rear end parts, if I want it to be.
I had to pay a little more than the $4800.00 [rice for the motor work and parts.

Re: 500hp

I drove a new Z06 a little while back and let me tell you that it's dam scary at first. Its the kind of power you can get used to though.

It's going to pull hard if you can keep the wheels planted...

Re: 500hp

well it sounds like you have all the candy you need on the chassis ---- that kind of horsepower is on the ragged edge for most small blocks though--- i cant imagine it being much fun on the street (big c am, loose converters, no vacuum, etc etc)

Not a lot do it naturally aspirated--- and not with most 383 or 406 based projects ---- 500-550 hp is quite a bit and is at the ceiling for most small block power combos . If you have the bottom end to back it up, sure, the sky is the limit with a turbo motor, a blower or nitrous .
A lot of guys make 500 hp in the garage with a cold one in their hand benchracing with their buddies, but then turn around and run 13's at the track.

That's odd, there was another post just after your last one that said that 500hp was the limit on a small block. Can't remember who posted it though.

I agree whole heartedly with you though. Forced induction is pretty much neccessary after 500 n/a hp
