Number of cyl/2 - change to 3

Firing order - change to 1 5 3 6 2 4 0 0

There will, of course, be other things that need changing like the fuel maps, timing maps, mass air transfer, etc. The things I listed above should get it running. Mike Glover, the creator of Tweecer, gave me the info.
any more info on this? what are the advantages or disadvantages? thanks

keep in mind that exhaust size should not be more than 2 1/2 inches for a stock or near stock 300
What is the reason for this

From: Coal Region
because the exhaust gas velocity will be slowed down to much and low end power loss will happen.

Does the EFI head benifit from the ported and polished head, I was under the impression that it actually took away from the intake velocity, reducing power, or is that only down low?

argh... sooo many questions...So a mild to moderate port and polish, and a 3-5 angle valve job should be all I do, rather than trying to get bigger valves in there?
