Looking for specs on anyone who has replaced the camshaft on a tbi engine. I converted my 305 4bbl to tbi a couple years ago. I recently read that to get the most out of the tbi i should also get the right cam. After some research, it looks like the carb cam is very close to the tbi cam (a couple degrees here and there). I am not a cam expert and was expecting to see a bigger difference. Would someone shed some light onthe subject for me, thanks,,,
