Johnny, I found your post very interesting..I'm wondering how much experience you have from which you speak??  The 7A motor "bolts up", eh??  If you are referring to the tranny and motor mounts that is correct, but that is where the bolting up ends.  What are you doing for fuel and ignition systems?  How about compression, you planning on running 500hp out of a 10:1 compression?  Are you positive that a K27 will even flow 500hp?  Just curious, you make all this sound so easy..
