need advice on shock and suspension setuo

Post by chevy art » Wed Jun 12, 2019 3:27 pm

my 67 nova with the 355 sbc(aprox 540 horse) used to 60 ft. around 1,48-1,50 and run about 11,00 to 10.95 on any given day and it had comp engineering slapper bars(tight to spring eye) and the old Koni Spa-1 front shocks. the car would launch and front end would come all the way up(no wheelie) and gradually settle down going down the track. car has 14 inch slicks, glide and 5,63 gears. front shocks were set all the way loose and i also had the comp engineering slinky front springs. rear springs were the stock parabolic mono leafs. and rear shocks were a mopar non_adjustable shock . syste worked fine. now i installed the cal_track bars and the cal_track 2 piece monoleaf springs and a good set of spherical end racing shocks with a single adjustment capability. they only have a 5 inch total travel capabilitr. i set the ride height at aprox 1 1/2 , so now i have aprox 3 1/2 inches of up travel and about 1 1/3 inches down travel from ride heigth. the rear shocks are set loose all the way(5 clicks). with new setup the car will not do better on 60ft times than the 1.50, but i ist extremely consistent. slicks are set around 10 1/2 lbs.(no less or the car wanders on top end) cat launches perfectly straight and now lifts the wheels off the ground maybe a foot. the problem is now the front end settlers straight down and then goes forward instead of the old way of settling on way down. i was told to correct this problem is to tighten the shocks about 3 clicks to tighten And see how that works. i know i need a better burnout, but i want to correct the launch problem. another thing i noticed is that when i push down on front of of car on the drivers side it really dont want to go down and the passenger side goes down with ease. i have not touched these shocks since 1995. caltrac bars are set like cavert said to do and the car goes straight so i wont mess with any preload on bars. any suggestion on getting my car to 60ft. better thanks Art in NY

I would agree with tighten the shocks. To soft of dampening uses up the shock travel to guickly. You have more anti squat with the cal tracs and getting more rise in the rear . Soft shock setting gives good initial bite but once the shock has no more travel the tires start to unload and you are losing maximum foward bite . Dan

Are you saying you haven't changed the shock setting since 1995 or are you saying you haven't touched the front suspension at all since 1995 . Either way maybe you shoud check for worn out or bent suspension components 24 years is pushing it a bit . You want the front end to move freely so the suspension falls under its own weight with no shocks and springs installed . If the shock is fighty friction in the bushings or bent parts it can not do its job properly . Dan

hey 6-50 thanks for the reply. front shocks are the original 1995 build shocks: koni SPA-1. 9010 shocks. i checked them yesterday and they are still real loose along with the moroso slinky front coils.. the rear had the original Mopar non adjustable shocks up until last year when i switched over to the caltrac bars and leafs. the new rears are strange spherical end one way adjustable . has only 5 clicks worth of setting and 5 total inches of travcel' i set them up for 3 1/2 inches travel up and the 1 1/2 inches down.im gonna go out next week and adjust them from all the way l;oose to most of the way tight(3 clicks tightening them. car like 10 1/2 lbs air in the 14 inch slicks(d5 compound) but with 10 pounds the car ice skates a little at top end, and even a little at about 330 feet out. maybe after tightening the shocks i will be able to go to 10 lbs. of air successfully without the ice skating at top end. and if i feel it just out of hole i for sure wont go all the way down to the end with the 10 lbs in the tires. car does run straight as an arrow and is consistent as can be but the 60 ft. times are way off. i have a big motor and good converter so my 60 ft times should be in the low 140s instead of 150. all advice is greatly appreciated... thanks again art in NY
