Well after looking at the darn corvair with a sick 500 for 6 weeks I finanly got to work on it some.When the oil pressure dropped down between 8# and 15 # pressure at idle and barely 18 # at higher rpm ,i quit driving it and waited till I had some time ect to go ahead and pull the engine and Im going to rebuild it basdicly stock ,hopefully nothings wrong with the #10 mts cam and crank.Its not going to be all out motor.The engine with the # 10 cam ran really strong in the corvair and Im happy with that preformance. I was reading a commit by Darius about any one still liking the caddy.In one way power wise I could make it easyer on myself and put in a ls. BUT I have had my corvair at the local car spots on FRI and SAT nights and the corvair always draws a crowd when I open the hood with that 500 ci engine. I believe it would lose a lot by putting a LS in it,guess I dont want to join the LS crowd. I'll stay older school. Richard richie49 Now gotta find some parts.
