LSM cam with alternate firing order ??
On my new 540, my engine builder talked to LSM about building an extreme pump gas motor - 10.5-1 compression - with 840 degree lift
and 1.8 T & D shaft mounted rockers..LSM wants to use alternate firing
order ( not just the 4 - 7 swap)... What do you guys think?? Motor must make at least 700-725 on the dyno..

I love them.
The C-Swap or 4/7 - 2/3 swap has no negatives. It hellps the engine to idle smoother and it runs smoother and is easier on the crankshaft. The cylinder temps will also be more even and more stable.
