Wow!~ I ran it for the first time at a local strip. I advanced the timing just prior to the race. I knew that traction would be an issue. I unleashed a 1/4 mile burnout. I backed off three times while monitoring my mirror. The right rear never grabbed pavement. Now my question is what rear end is in my car, how do I identify it, what is the cheapest way to toss parts at it for a posi type of performance? My car is a 67 Special with a moderate 455. It was born with the 300sb. Next race is in two weeks and I'm after a low buck solution.ray:
I'm gonna guess you have a 2.78 peg leg 8.2 in there if it's stock. Best bang for your buck would probably be 71+ 8.5. Go here for info: http://www.buickperformance.com/85rear.htm
I saw a cute li'l 16 year old chick make a 20+ second pass in a 6-banger Ford Falcon. That Buick's got to be better than that. Did you do it on ice? :bla:
Is there anything George does not have on that site! LOL We all need to check there first! :laugh: :beer
If you're looking for a quick, temporary fix, I used a set of Air Lift drag bags in my rear springs, 25 lbs. in the passenger side and 5 lbs. in the driver side. This, coupled with some sticky tires, M/T drag radials in my case, pulled off a 1.91 60 foot with my 2.76 open 8.2 rear. Luckily, just finished my 3.42 posi 12 bolt swap :beers2: Best of luck!
Feather the throttle through the whole run. Maybe take 5psi out of the tires, don't go too nuts with that though on regular street radials. My Centurion, essentially stock '72 engine, 5,160lbs with me in it, 2.93 pegleg rear, regular street tires at full pressure, feathering the throttle for traction until ~3,000 rpm (still had traction issues hitting 2nd gear) pulled a 15.58 seconds.
