Disappointing dyno results

Well it's obvious I need a different cam. While I have everyone's attention, I understand Oregon Cam Grinding has the template for 68 340 4 speed cam.
Yeah man, they are a solid vendor too. But I’m going to echo what the others are saying about your cam timing. You need to verify, if you accidentally put it in retarded(no big deal, regular mistake)by going dot to dot. I would double check everything before you start spending money.
