Need help mounting my 350 and 400 tranny in my 50 chev. The Mustang ifs is in and done. I would like to mount the engine. questions though, is it possible to squeeze the engine in without cutting the firewall? If so, is there room up front for the rad? Use the 350 rad? Mount engine directly onto mustang x-member? How low on the x-member should the engine be? anybody out there whose done this PLEASE help. :confused: Thanks.
