M5lp 1007 02 Z Roush Propane Racer Development Engine
3 of 12
The development engine for the Roush propane racer is a stock-displacement 5.4-liter Ford GT supercar long-block, modified for wet-sump oiling and bumped to 12.5:1 compression. Its internal specs are otherwise unimportant because, in race form, the project will run a larger displacement variant, as detailed a bit further on. When plumbed for gasoline, it produced around 635 hp on C14 fuel. With the liquid-propane fuel rails and injectors in place, power was about 625 hp even, though for baseline testing purposes, about 3 degrees less ignition timing was used.
