IO360s fire 1-3-2-4 not the sme as car engines so this might not be the best setup.

Thx for the reply. Do you have updraft or downdraft cooling?? I like
the idea--simple, saves weight and possibly less heat transfer in the
engine compartment. I just spoke with one of my neighbors who is an
absolute guru in powerplants. He favors the 2 into 1 systems but only
when it's the 1 and 2 cyls together and 3 & 4 together seperately. He
had run several tests years back with MustangIIs he had built and found
significant speed/horsepower gains with this type config. I've got a
single crossover 4 into 1 now that is probably the worst setup to have.
I'm going to pull cowl tomorrow to see if his suggestion is feasible but
I doubt there's enough room for dual crossover. Standard 2 into 1 is
probably the way for me to go.
