Chevelle wheel hop
Hey guys!!! I have a 68 Chevelle, street/strip car with a 406 sbc and a 4-speed and 12 bolt rear. I have added rear poly bushings and boxed the controll arms and have the "No Hop" bars (they raise the mounting point for the upper control arms and have solid bushings). I have run these no hp bars for years with my old tired 350 and they worked great, with slicks they make the rear suspension seperarte and, in therory, plant the rear tires, now with the 406 the car either bogs bad or spins. I have tryied all kinds of different things to remady this problem and nothing seems to help. recently I decided I was going to remove the "No Hop" bars and install poly bushing back into the top ears of the axle housing. My thought was that I will change the angle of the upper control arms back to stock and change the instant center, so as to not hit the tires so hard, maybe take some of the shock away. so I did that this week end, went out on the street, dumped the clutch at 2000 rpm and wheel hopped like a mad man!!!! WHAT THE HELL!!! so I tryied to do a burnout, HOLY CRAP!!! even worse!!! My question is WHY??? every one I talk to says that poly bushings solved there wheel hop problem. It should all be pretty solid back there!!! Also being Im asking, say I had no wheel hop problem, is my thinking correct?? Would this help? Thanks guys for letting me ramble!!!

wheel hop
Hey thanks for the response!!! The people I have talked to are people I know that go drag racing with me. One freind of mine has a 69 chevelle that runs low 12s and high 11s, he has poly bushings and old stock shocks and some "overload" springs. I also talked to a guy with a 69 chevelle that was running low 9s!!! with a big block , I asked him about his suspension, he said he had poly bushings, stock springs and the shocks were on the car when he got it. that car would pull the front wheels about 4ft in the air!!! The only exception is that the people I talk to are all running automatics, so I would im agine its not such a hit to the tires.
