ok guys, I'll try and remember to get the article from work tommorow.... I spoke about this before.... in a ford truck mag, they built a hi and low comp 5.4 4v motor, took hp readings, then slapped a blower on it to see the results of boost on the diff motors to see the results of high comp vs low.... with a built short block, ported 4v navigator heads, and the cams they were running they pulled 1,032 hp on the low comp and 1300+ on the high comp motor!! for way under 10K then all you'd have to do is get the navigator harness and swap it over. Run all the same accesories.
some of you may have the mag... it talked about the Roush F150, and the saleen f150 It's not but 8 months old I think
here's the article in another mag
