Good advice from Stock car driver. We start with the standard 16" upper and 13.5" lower bars, then adjust the RR fore or aft to tune the car for track conditions. I suppose GRT tries to keep it...
-
An offset rearend does not necessarily move the pullbar laterally in the car, in order to make that change you would have to move the chassis mounts in order to keep the pullbar alignment correct. ...
-
Likely that fuel burnoff is a lot of your problem. The amount of rear percentage lost, with the tank hanging where it is, and with the amount of alcohol used is substantial. I know most sprint car...

When you say the car "fades", what exactly is it doing?
-
RaceTechKs, your reference to guys spending a lot of money on dyno time in order to get everything out of their crate, is irrelevant. We have 2 open engines and 1 crate, all to run UMP b-mod, and we...

I have a guage legal E-85 2 barrel built by John @JDR Performance. $200 Good carb by a great guy to deal with. Was on a B-mod, we switched to sprint cars so no longer needed. Also have a 1.68...

The old, outdated sprint cars are faster and more exciting to watch than any other cars. They are cheaper to maintain and repair than a late model or even modified, plus the payouts are generally...

I saw this happen twice at the beginning of this season, on the same engine. Builder blamed the valve the first time, but 2nd time it got sent elsewhere. Had 10 degree retainers with 7 degree...

You will get answers both ways, most of which is speculation and here say. we may take the car you looked at up to the dyno this winter and make some pulls with both and see for ourselves. I am...

They are nice race cars, a lot of guys winning with them. Jumper is not a bad guy, but getting ahold of him is a real challenge.

Looks good, what a stock car should look like, a STOCK CAR!
-
The rearend was square with the ride heights we were running. After changing all 4 heights, the rearend was out over an inch.
That is a problem I have seen guys make, not rechecking and aligning...
-
we were fighting the same thing on our Impressive, coar just had no drive, loose everywhere. Jumper went thru everything with us, ride heights were off. Readjusted heights and resqared rearend, it...
-
Put engine on the stand, bolt on the 153 tooth flywheel, get a mini starter with straight across bolt pattern and bolt it on the block with the outer bolt and turn it to get the right mesh on the...
-
We just sent our ATI super damper in for a freshen and they sent it back and said it was worn beyond repair. It looked fine on the outside and showed no signs of damage. There must be something in...
-
As for "bang for the buck", the old 383 sbc is hard to beat. Countless races have been won in everything from bombers, b-mods, modifieds, late models and even sprint cars with 383's. I have built...
-
What would you recommend for a fuel pump on an alcohol modified? We were running a six valve Barry Grant, and didnt have any trouble, but its time to replace it. Have heard more bad than good bout...
-
I would definitely hard-blok it. We have done probably 10 of our motors over the years, from 2-bbl street stocks to alcohol modifieds, and have never had any heating issues due to it. Just seems to...
-
Is the front to low or the rear to high?
-
Would also make an excellent enduro car. runs like a top and body damage isnt too bad, I drove it off the trailer and around the yard. car has aftermarket 16" alloy wheels as well
Can text or...

Not enough info, a 400 c.i. engine could be anything from stock to 750 hp.
Yes, 400 is big enough depending on whats in it.

Very friendly and helpful guy, and reasonable as well.

I have used a couple of them in our mod and e-mod engines. Never had any problems, but again we were turning around 7000 tops. We use 6" Scat 7/16"
capscrew rods with SRP pistons. With...
-
If you are set on using the 350 block, why not put a 3.750" crank in it and gain the additional 30 c.i.
-
Can you use a piston designed for Brodix 10x heads with any other 23 degree head? JE piston site says custom pistons are required for the 10x.
What I am wondering is can I take a shortblock that...
