First start and have some questions.
Hello my name is Vince. I currently built a 327 with a Big ***** Thumpr cam. (12-602-8)
Yesterday I was trying to fire her up for the first time. After moving the distributor around a few times I seemed to have stoped the backfire out of carb and mostly out of exhaust. My problem is it will not fire up. It pops like a mother and wants to start but just cant quite kick it.
I heard that on alot of these newer cams that the #7 and #4 firing orders are reversered to create more power? Not to sure, I have it on the Normal SBC firing order.
Also, Im going off tangent but im trying here, I feed the motor more gas from the carb obviously wants to fire but again it doesnt.
QUESTIONS!
What I am asking is does anyone know about this firing order mix up?
The cam also comes 5 degrees advanced. Do I need to make up for the on harmonic balancer or do I just keep the balancer at zero?
Im gonna try different carb because I beleive It might just be a fuel problem.
Anyone have any thoughts?
Sorry, Im terrible at explaining. If I need to clarify anything In can.
Thankyou In advance, Vince.
