Re: firing order
watched ENGINE POWER this morning where they built an engine 580?something . their bump stick had 4 and 7 firing order reversed why?
they also used a belt driven distributor . is there that much advantage doing this?
The 4/7 swap is supposed to smooth out the power a bit. The cam in my motor has a 4/7 swap. Belt driven distributors are typically used if you have firewall clearance problems. They have to be used with a crank trigger. A crank trigger is more precise than having the pick up in the distributor.
