Re: Oil consumption & smoke on a 327/350 hp
Even with the correct (I think it's green) spring in the Melling pump the pressure will be higher than was original. It will not pass PV in 67 class. You need to be about 10 to 15 lbs lower. This requires the spring be custom massaged. I will have a real original GM pump at Carlisle. Also should use a 10W30 weight oil. Higher than necessary oil pressure robs horse power.
