Ok well I have been working on my 1978 PW 1/2ton with tmy 440 v8. The gas output in the exaust was high. I have done a compression check and all of the heads came out from 130psi to 150psi and my book says it should be at 100 so I know thats good enought to forget the head rebuild. I have a new Holley Carberator on it so I was thinking of down jetting it and mabey putting in a high output 4x4 Coil and sparkplugs to burn any unburned fuel... Anything else I should check? It dosnt have a smog pump.
