you need to put money into a "crankwalk" savings plan....lol thats what i did...but my motor never walked , but i still went 6 bolt...for different then yours...Listen if you wanna go 6 bolt to have that "sense of security" then go ahead....don't listen to what anyone else says...sure take their advice if you want, but ultimately it's up to you....sure you could make 400hp on ur 7 bolt...but then again you could of sold that longblock and got yourself what you wanted...and save a little money in that aspect. But dont forget, if your driving a modified car....sooner or later somethings going to happen
