Sweet jesus.. aren't the 6.4 heads in the 150 range?
5.9 12 valve is 120
24 valve 140
duramax 165
not sure on 6.4 never done a set
The 6.7 intake track is never going to be a problem
The injectors are at 1250 pulse when they drain rail.
We run 3000 pulse on dmax's no problem.
Plenty of injector capacity.
This engine has allot of potential and is real easy to work on.
And the piston bowl design is very nice.
My only complaint is that there are no tabs on the rod or main bearings and they are a pita to line up. I have never seen this before and there are allot of spun rods. I don't like it, but I can't say for sure its a bad thing.
