Thats bull about torque. The 6.4 was engineered to produced more torque down low because although its first iteration made like 500hp it didnt feel much stronger than the 6.1. Thats when the variable length runner intake came into play. SO now the 6.4 "feels" stronger in the 4300lb land barges they put them in. Yeah im pretty sure torque was at the top of the list with 6.4, even though the ports dont support that.
Mopar to the bone!!!

I don't agree with the overall results. IMHO a Apache, ported or not is better suited to a 440 and above.
I've dealt with a racer in direct compeition to Alcharger. He ran less cylinder head (eagle) and was still faster over all and also less CI.
An effcient head is what we build for. Different styles work for different aplications.
A lot of what you're saying makes sense, Alex. You've probably forgotten more than I know about the these new hemis. But I still can't get around this: why would Chrysler spend so much money in R&D to design a new head for the 392 if the older 5.7,6.1 or eagle would have made more power? If it's a low end tq issue, that could have easily been reduced electronically. I can't help but think the engineers wouldn't have done it if the port velocity was that bad. They still did despite the low compression,small cammed,low stalled, and heavy application. I believe that was infernalAl who did the head swap on his stroker; eagle to apache who picked something like 40 HP to the tires.

Someone really needs to build a 434 or bigger out of a 6.4 and see just what its capable of. If anyone has about 10K burning a hole in their pocket I will take one for the team and graciously volunteer....

Just went through this entire thread. Man things have changed! 6.1 is dead. No more blocks If your looking to go big cid aluminum or 6.4. STEFF is the only one I know that has used a 6.4. The 6.2 Hell Cat is rumored to be coming out in alumunum. WHYYYYYYYYYYYYY The 6.4 has a bore of 4.09 some its got something. Plus I THINK they used the 6.4 block with a 6.1 crank to test the supercharged challenger. If a production block survives a 700 hp trashing then I won't need anything stronger. Matt Forgot the 2014 2500 and 3500 come with the 6.4. Same block and crank. So with the selling of trucks maybe the block will be more abundant.

What heads do the 6.4 truck engines come with? Eagle heads (smaller port better torque) or do they still have the Apache's? Or an all new casting?
I'm thinking the same thing the 5.7 casting. IMO Apache is too big too expensive. But you know how they are!
