    Bruce,

    Thanks,

    Jim, the hrPartsnStuff bar is not yet in my car but should be ready this week. HR's bar is a bolt in style and requires no welding.
    the Wolferacecraft bar is a weld in piece, though it doe not attatch to the roll bar, it is welded in between the frame rails and attaches to the rear axle.
    the won like Robs and Bobb's is welded to the roll bar inside the trunk, which is the best? I don't really know. but they are based on the same principal, just a little change in design i suppose.
    I will be installing HR's bolt in piece and report the results as soon as possible, I like the fact that it can be bolted in fairly easy, they have been testing this bar with very good results on a chevelle, and a few turbo cars as far as I know there just finishing the details of this system and getting ready to ship them out.

    The only reason i installed mine in the trunk was because clearance issues with stock gas tank and exhaust system.

    I have the HRPARTSNSTUFF bar on mine and it leaves level. 1.41 60 ft. I now need to get more weight transfer by getting rid of the Southside bars.
    This is a very nice product and is easy to install.

    I spun REAL bad in elims at Etown this weekend but the track was not being maintained very well.
    Also, one guy ahead of me did his burnout BEHIND the water then burned thru it!

    The track conditions weren't that bad! A bad racer can get down a good track but a good racer can get down a bad track. Dave Saye with the clone GSX ran better this weekend then we ever did with the 850 Holley. 10:74 @ 125 with a motor with over 725 runs. That motor is amazing since the pistons and bottom end was done back in 1981. Scotty from PG did rings and bearings back in 1995 I believe with some head work and since then over 725 runs!! Best run we ever had was at Cecil thru the exhaust with the Dominator was a 10:66 @125.

    It was bad when I went down in elims. I'm just saying they didn't clean it after a spill or whatever that well.
    When you hook perfectly on the first two runs then go sideways on the third there is a problem.
    I've been spoiled lately running the NMCA and PRO Edelbrock races at Cecil, Pittsburgh, Maple Grove and of course Norwalk had fine traction.
    Rick Miller wasn't hooking consistently either.

    What was with that Olds guy starting his burnout BEHIND the water?????

    Very fine event nonetheless, John!!

    Is that Scotty's old motor from the Electra in Dave's "GSX"?

    I remember seeing it run 11.50s on spray at the Nats....what like 1984?

    robsbuick, i really like the set up that you just installed. i need a anti roll set up for my ride and i like the idea that you could keep the tail pipes. i have a terrible problem with body roll and was told by a member on rop (scott smith) that you buick guys have a grip on this and that maybe i could get some soild help here.
    any info that you folks would be willing to share with me would be gratefull.

    I have a few questions i would like to ask you guys if its ok

    Jim Weise,

    I was wondering if those aluminum arms are splined or bolted?

    They are bolted.

    Jim,
    You have a nice looking chassis there and I would strongly recomend you loose the aluminum arms for some weld on steel arms.
    Those aluminum arms will never be tight enough even from day one. And after that they will only get looser.
    The only aluminum arms that are currently working well are on the 4 link dragsters and they have large splines.

    Just trying to save you some grief while you can still make changes.

    I dug up a picture of a C/M setup.

    HRpartsNstuff, anti roll bar

    I installed the HRpartsNstuff anti roll bar with the help of the owner and his brother paul and chris ferry, last weds evening, and made the trek to Indiana for the Midwest Buick Challenge.
    I set the bar as Paul and his friend Dave England recomended, and set of for the staging lanes, all I can say is WOW!!! the car squatted downnice and even, the front wheels about 4-5 inches off the ground, and absolutely dead straight launch! every pass!!
    This is a bolt on system that can be done in a couple hours, they even supply the drill bit and all needed hardware, so you could actually bring a drill to the track with a tape measure and marker and install it in the pits.
    HRpartsNstuff has put a ton of time and engineering into this project, and it clearly shows in the abillity to stop the car from twisting so violently at the starting line.
    congratualtions to Paul and HRpartsNstuff for a top notch product.

    Bruce,
    How does this work on the street?

    Doug, probably a question for HRpartsNstuff, as my car is set up for the strip moreso than the street, I do a little street driving from time to time , however not yet with the bar. I would assume it takes out almost all body roll.

    I drive mine on the street....no problem. Handles alot better.

    One thing I'm noticing is that the bar seems to be trying to shift in the poly mounts toward the driver side after 10 runs and 20 miles of street. Trying to contact Paul about it.

    I'm thinking of possibly drilling the bar and putting a bolt thru with a washer to keep it from trying to shift and also keep it properly aligned with the vertical "heim" joints.
