there is nothing wrong with putting a blower on a engine,infact,Chrysler has been putting tubos on cars for over 20 yrs. The ford engine is a 5.4,compared to the hemi 6.1 it's a high efficiency 4 valve set up. guys are getting over 1200 hp with stock blocks. Great engine. Yeah,u need 92 octaine,but it's worth the fun..
