Greasemonkey -- I'd think twice about putting a 427 or 428 into an FFR. I know guys that have even put in 460's, but they're all a tight squeeze and don't help the handling. Since you're not going for ultimate accuracy, a small block (302 or 351 based) will be a lot less expensive and you can make a lot of power with them. There are several incredibly fast 351 stroker FFR cars out there... (SPF's too, for that matter...)

Just my opinion.
