I have been seeing the 392 hemi out now, looks pretty stout at 525+hp! not to shabby. The thing is the price.. $16,000 for this thing! Ive seen it between $15,800-17,000+. When a 5.7 can be had on ebay for under 5k there is now way you can't build one of these for a whole lot cheaper.
Ive seen the XV guys around here, what can you all build this motor for? how bout the 426? if the 392 can do 525hp the 426 should be good for 550+ right?
