The 468 is an aftermarket aluminum block motor. Totally unecessary and a big expense for a Gen III unless you're wanting to cut weight, factory blocks are more than adequate. Thiteks aren't cheap, but I'd venture to guess you could get the cfm needed from an Apache/Big Gas/HellCat head. The 468 I posted wasn't maxed out, it was still using a factory intake (ported) and 12:1, room for more compression and a better intake
Thitek head is not just a copy of a stock head. Its port is raised and will outflow any of the factory heads. Plus you can run a dual valve spring making it far better for what we need to do.
That 468 has the 2.20 titanium valve Thitek heads on it. Ported stock 6.1 intake is extremely good. Long runners but still flows very well. And you can only build an engine that big with a factory block if you darton sleeve it.
