Re: Front End Suspension, NHRA Rule Question
I installed global west kit with factory cross shafts in mine, since i was unsure of the aftermarket shaft, Easy as pie. It also has upper ball joint spacers, aluminum, about 1/2". 350/255 combo leaves pretty hard, But not like the above crazy hp big block bracket car that should stop commenting on the class racers board.

First and foremost I want to be a race track, running this car with my Dad, Father's Day weekend of 2014. Then run it for the summer and start picking it apart after that. At that point, it's ON! I am lucky to have access to a full CNC machine shop, Solidworks and I can TIG weld. With off site access to laser scanners and feral arms, my only limitation is the time and obtaining actual proven racing knowledge from cats like you on here. Thanks.

Re: Front End Suspension, NHRA Rule Question
Andy, those cross shafts aren't any better than stock and more important they will do nothing as it relates to making this car work.
That said, there is no one posting on the net that knows better how to make these cars with small tires and stock/aftermarket/bolt on suspension work better than I. Further, there are only 2 other Chevelles and 1 Buick GS in the country last I knew or cared that are on par with my former car and they belong to Kevin Borgstrom '69 Chevelle B/SA , Ralph Landolfi '71 Chevelle B/SA(if he hasn't sold the chevelle yet) and Jason Line '71 Buick C/SA and what do they all have in common...they all run front and rear suspension kits designed, built and sold by Alf Wiebe and only one, the heaviest and least geared had 60 footed 1.28. IF you want your car to work like mine and theirs, he's the guy you need to speak to. Do it right the first time. There is no bolt on suspension kit/parts on par, no mind better. Be advised, that even with the best, the end user still needs to tune the suspension and chassis to achieve the results I have which becomes evident once you know that the chevelle in the other lane in my video below also has the same suspension components as my car, going down the track with his front wheels on the ground at 10 seconds in while my car which btw weighed ~ 180 lbs. more IIRC is still carrying the wheels.

Re: Front End Suspension, NHRA Rule Question
I did buy stock upper control arm bushings and machine the "teeth" off the ends of them, then took brake cylinder hone and honed the inside of the bushing so that it slid on and off the shaft easily, then greased them really good, I used the moog kit with the offset upper shafts.. It was really free moving after I tightened everything up and saves you a ton of money.. if you look on alot of the good working stockers alot of them are this way..

Re: Front End Suspension, NHRA Rule Question
all I'll say is that everything that can be be done, has been done with these near 50 year old cars as the rules stand now. Would love to hear and see how you made out with this car in 3 years. Do come back and show us.

Re: Front End Suspension, NHRA Rule Question
removing the "teeth" aka serrations has been done for at least 40 years. The bushings I referenced do not have serations.

Re: Front End Suspension, NHRA Rule Question
I got that part and it's all good. I have a defect of often trying to re-invent the wheel. Even in the end if my 'wheel' performs the same and cost a lot more than buying it from someone, I can say that I made it, from scratch. I will share any and all that widgets that I come up with as the project progresses.
