I would also like to figure out if the cam its equipped with is for a fuel injected setup??? I know they post the specs and figuring out good swap in for a carb motor would be different.

Yes I still have the ram horn manifolds and there is no interference issue with the spark plugs. In fact it worked out great. I also used some repop heat shields and they worked fine but I did have to rework the right rear one for use with the oil dip stick tube.

The L31 factory cam does not have a lobe for the fuel pump and the block is not drilled for a pump rod either since they were all fuel injection at that point. I have a 5psi rated electric fuel pump mounted on the frame going to the carburetor.

Hope this helps.
