My brother has a 64 wildcat he cant seem to sell. they all just want the mtr and I ahve had enough off the new crap and all ther outragious costs to tell you wahts wrong. So i might buy his car minus the 401 and put a mild built 455 in it. I know the towers wont work and Im ok with what is all going on with this but my questions is will the center section hold up to a 450-500hp 455? can i geta custom drive shaft made for it that will be big enough in diameter as to go threw the X in the frame? or to I have to cut and mod. it? and is there any othere tricks or anyone thats done this? I would bild the nailhead but I have almost all the parts for the 455. and its easier to make more pwr with it Thanks Doug
