Hi,
I'm new here and was wondering if you guys could help me out on my 1/8 mile drag car. The car is a 1965 chevelle 3070 w/driver. It's an old racecar that's been sitting for a long time (27 years). I had it out a few times in the past few years, but never got it to work like I felt it should. The specs are as Follows:
New rebuilt suspension
Santhuff 180 lb springs
Calvert 90/10 shocks
Global west del a lum bushings in upper/lower control arms
Global west offset control arm shafts.
Welded in suspension limiters
Back:
12 bolt Chevy narrowed
6.14 gear
32x14 Hoosier slicks
4 link
Strange 3 way adjustable shocks
Panhard bar
Qa1 heim joints.
Engine:
355 sbc making around 420 hp
Powerglide 5200 stall 1.82 1st gear.
Car last trapped 92 mph 7.44 et 1.61 60 ft and old very worn suspension. (basically every wear part front and back)

If I remember correctly the car had a 42 in instant center and 1 degree pinion angle. Is this where I should start again or try something else. I will get a map of 4 link this Friday, trying to race Sunday. Any advice? Thanks

Does it really have a panhard bar diagonally across the rear? I think that is a problem to the 4 link functioning correctly. The 4 link wants to move vertically up and down in the car. The panhard bar makes the rear want to move left to right in the car as it goes up and down. Effectively binding up the 4 link. I would remove it and go with a simple track locator, that bolts to the bottom front on one side of the 4-link and the bottom rear of the opposite side bar on the 4 link. What rate spring is on the rear shocks?

With 14x32 slicks and a 355, you ought to be able to hook on a snow covered dirt road!

I can't see it even attempting to spin the tire even if the setup is not perfect.

Yes it is a panhard like you described. I'll get pics when I'm on my computer. (can't on my phone)

No body asked but I would hope the tires are not 27 years old.... :scratch:
