Nobody's addressed the fact that this would drastically lower the already low compression ratio, that's why 2V heads make 12:1 on a 4V bottom end.

just continuing the discussion, anyone know about the 05+ 3v motors?

I stand corrected and apparently can't read. 8.5:1 isn't as horrible as what I was thinking.1992 CVLX. 5.0 HO/GT40P/T5/3.73/trak-lok with bolt ons. 02 front CVPI setup, rear HPP setup, CVPI shocks around, F250 radiator, e-fans, and the power of 3G. 15.92@89mph, 2.4 60', 4700' elevation (5500' DA) with 3.08 open rear and the old oil chugging 289. RIP.

No. But it's prime for a blower or forced induction of some kind. I would run too much boost without some internal upgrades.
