road car cam for my 318

With 8.5:1 compression you want a short short duration cam like what @RustyRatRod suggested or you will have no dynamic or cranking compression and will suck for a street engine. You also want a small LCA (like 106 degrees) if still the stock heads. I would call Ken at Oregon Cams and get a 2016 grind at 106 degrees. My opinion.
