L78 firing order swap
 

Dear all
Talking to one of my racer buddies, he recommended swapping 7 and 4 I believe in the firing order to get more horsepower
Any thoughts ?

For what you're doing, it ain't gonna be worth messing with...last I knew it wasn't a significant pickup of HP, more of a harmonics/longevity thing...https://www.yenko.net/ubbthreads/imag...lins/dunno.gif

Howie or Sam and their S/S buddies would probably know more about that...

Did your buddy mention that in order to do the 7/4 swap you must have a cam made with the lobes swapped also, there are some cam companies making these but they ain't cheap and they definitely are not street cams.
