[New to the A bodys]

Good morning, I have a 69 dart with a stroke 440 with a 871 Wieland blower on it. I just bought this car and it is back halved with 33-19.5-15 tires on the rear. The front is to low for my liking, the oil pan is 3.5 inches off the ground. I would like to raise the front at least 2 to 2.5 inches. I do not know what size torsion bars that are in it right now. Nor do I know how to tell. Could someone recommend me a torsion bar size to do what I am looking for? I am going to race this once in a while but also drive it on the street. Thank you in advance.

Hi,
Why don't you give Firm Feel a call. They manufacture Mopar torsion bars in house. The more weight you have in the front end, the larger diameter bars you'll need. It looks like they have 5 different sizes. I bought their bars about 12 years ago and they're working great. I think mine are the 1.00'' diameter. With an 871 blower you might need to go bigger.

Originally my 69 Cuda formula S was a 340 automatic, power steering, A/C car. The stock bars were .875" and after the point of contact with the torsion arm took most of the threads on the adjusters to establish ride height. When I installed the 470B automatic power steering, A/C (aluminum water pump A/C Compressor, heads and intake) I increased the bars to 1.03", now it only takes two or three turns of the adjuster after point of contact to establish level rocker panel ride height. I can easily adjust it up stupid high like a gasser with these 1.03" bars. The stock body and K member are reinforced (heavy), has steel bumpers, factory brass radiator, stock battery location, full interior and an overweight driver and companion Ride is solid but not harsh and road handling is much improved. Note that as the bars get larger in diameter the spring rate per 1/8 inch change in diameter rises dramatically.

on a street car i like at minimum 1" bars. but that may hurt your weight transfer at the track.. i guess its all about what compromise you want to make..

couple of choices...
