the car is fun to drive as is...it does need some tuning and I need to get rid of the points...have lined up a bunch of v8 buddies to give me a tune at BPg and I will take if from there...it is not a race car...i would like to swap in a posi rear but with current trans and switch pitch converter it will not break tires loose...so if anything a trans an converter swap is in order...but then you take away from the original aspect of the car...I do not think a suspension upgrade takes away from the originality of the car...but then,,,who knows...
