I have a 66 270. 273 Engine I've noticed most of the cars on this post are raised up to allow bigger wheels/tires. Did you guys use air shocks or install new rear springs??
The only good way to raise the rear of these cars is to install new springs. If the rear sags you need new springs anyway. You can get some in1 or 2" over stock lift. Try ESPO Springs and Things or PST (who sponsors this site.) or I believe Mopar Performance has them available too for around $100 each. I have seen them on the Summit website. tmm
