Well, my motor building skills are amateur, so it was lining up the dots. I did pick up a degree wheel, but it was after the build. The plugs look clean. The cam is a pro comp cam/lifter setup. I have to find where I wrote down the duration/lift info, but compared to the cam in my Challenger, I would say is very close to a stock build. I rebuilt the carb, used factory jets, and it does run fine, no hiccups or backfires. I am considering the Edelbrock performer intake, and a new carb..either that or I need to buy stock in Shell to get some of my money back...
