Yes, the cfm achievable on the Gen3 is crazy. The 2
`12 on up(Eagle head) will go 330cfm without much work. Pretty darn good for something you can find in a wrecking yard. The Apache heads are over 350.
I agree with YR, Fiat gave us the finger. No blocks. If it weren't for the aftermarket it would be impossible to build anything LA.
Once parts come more available for the Gen3 hemi, and costs come down, we're going to see a lot more of them.
