why not install a all aluminum 427 ci small block as they are available from different engines builders? that way no fitment problems

Mark, You may encounter fitment problems with the 5 speed tranny if it is a Tremec. The Tremec is a large tranny and usually hits the top of the tranny tunnel in the floor. I had to use a combination of spacers on the tranny mount and also raise the body nearly 3/8" by using rubber wedges between the floor and cross-member. The end result was worth it for me.
