But Nova's usually just "Dog Track" they usually don't sag to one side or the other. I always thought it was odd seeing about 50% of the Nova & Nova based cars Dog Track at a severe angle, but the Camaro & Firebird Models that use basicly the same chassis and were usually driven much harder don't see to have the same issue? I see that is one of the wonderfully unpowerful cast in head intake manifold I-250. They are not bad cars and all the 2nd gen F-Body suspension parts bolt on to them so they can be made to handle pretty well, possibly better as they are usually about 500lbs lighter than a Camaro or Firebird.
If I was to have one, I'd scrounge up a truck 250 head that mounts a Varajet 2-stage 2-barrel. No computer controls, just the carb and HEI.
