Lessee...$14,500 for the Government Motors engine vs. $7 K for the Ford? Apples & oranges, money wise...
But if you believe there is no replacement for displacement backed by cubic dollars, I'll take that 550 horse chevvy and raise you... http://www.fordracingparts.com/crateengine/main.asp

Yep, computer management systems allow for some pretty high compression ratios these days...even for use with pump gas.

Image what you could do to the 5.0L with the 8k difference to the 427. Anyways It's all aluminum, and twin cams... Goodies would definitely be cheaper then to the 928 5.0L

Cubic dollars win it all. Look at the F-1 engine.
