Im curious as a real answer too , I wondered the same, but since none of it matters as he could register it as a 2020 Lear Jet Car with a 900inch motor.... as long as when he techs he techs it through as whats proper none matters.......
The 6.4 was disallowed by the NHRA on the original DP specs for several reasons, 1 of which was it was not available in a production vehicle. ?!?! But....the "comprimise" from my understanding were the available displacments and the non ported heads etc.......(6.4 crate motors as of now have ported heads as well as other "goodies")
I would be suprised but not shocked if the NHRA let them in now, the truth is the 6.4 that WILL be available has more potential with the VVT the crates dont have.......the ramp up make power, 5.7 "Street" challys with the 5.7 vvt and a tune run as fast as the 2008 6.1 ( a bit lighter too) .....
The 6.4 "street" motor will be a formidable force for certain, street or track.

Just curious as to whether the 392 will be approved at the last minute before the Winter's . Steve
