There is a place in visalia, ca called wheels of steel. They will build you a wheel with any back spaceing you want. They will be steel though. What tire are you running? The rear needs to be stiff with an air bag in the right rear spring, with a little preload. The front must be as loose as possable. Also the pinnion angle is important.

 

Is that with stock pistons?

Thanks.

 

Stock engine, hasn't touched the internals. The only thing he's changed is vavle springs, other than that the whole block is stock from top to bottom.

 

i started making the truck 2wd and got sidetracked. didn't steal any parts yet but we might borrow a few for another project.

the motor is stock other than cam and springs.

we just got the rear narrowed. used a sawzall and cut 1.25" off each side then welded it back together. the moser axles we had were splined enough we were able to just cut them down. the tires we have been running are 26x8.5 but now we have a set of 28x10.5 on the way so it should do much better. we had a bag but got rid of that and went with a rear anti roll bar. we have some decently stiff springs in it in the rear. front is prety much stock. pinion angle is -3deg. intersect angle is 48" at 12" high wich is prety close to where people sugest we aim for. i bet we get some consistant high 1.3x 60' times with the tires.... i hope... there will be vid if we get some good wheel pulling action.

 

Can we say it is the fastest 5.3 Vortic in the world or fastest street

Fairmont?

 

Yeah that thing is haulin! Parish, what sort of RPM does the 5.3 see and do you think that has an effect on longevity?

 

I'm just wondering if there is a secret ratio to timing versus boost. The best ratio may not nearly be the horsepower King... but may be the longevity King. I am running 9psi... 10 on an 85F morning. Zero detonation. If detonation "never" occurs... can one excercise 15-18psi of boost yet never exceed cylinder pressures that destroy pistons and lift heads? Certainly if Jim is running stock head bolts and not lifting the heads... that certainly says alot

The light car and loose converter are easier on the engine than if it was in a heavy truck with a tight converter. Still really impressive though. Would still be in the low 11's in a 2wd truck.

 

car is still running strong. went to the track a few more times. ran a best 1/8th of 6.31@111 with it cranked up and not even all that great of a 60' i think this car will go 9.70's on a good day. then we put some drag radials on there, pump gas, drove it to and from the track and ran a 6.92@100 with only 7psi. i think this car will go 10.70's or so on pump gas. we pluged up the fuel filter but other than that no issues to report.

 

i bet yoru having more fun with that toy then you do with the beast of a truck you own. did you get any dyno numbers for that
