6.4 build

I am very interested in building a 6.4. Looking at getting a newer PW mostly for off-road use but I would like it to be fun to drive on the street. The truck motor has lots of potential.

I have done some research but Iím a bit confused and need some questions answered.

What HP/TQ can I realistically pull out of this motor?

Is the truck 6.4 Apache heads or Eagle Heads?

Who makes a good ported/polished head? Or is there a shop out there that will do the heads?

What are there out there for camshats that will wake that motor up?

Thank you for your time/advice

"What HP/TQ can I realistically pull out of this motor?"
400/400 is very doable with the right parts, read Chris 6.4 Build thread for an NA Engine , Stu's 392 build for a Turbo engine


"Is the truck 6.4 Apache heads or Eagle Heads?"
Factory 6.4 engines uses Apache Heads, the 09 and later 5.7s use Eagle heads.

"Who makes a good ported/polished head? Or is there a shop out there that will do the heads?"

as for cams , thee are a lot of good choices out there now, depends on your goal.

Welcome to the forum.. Martinsville is a hot spot for hemi performance shops. API is sold to a northern business group. I'm going to miss them.
