Out with the 305TPI and in with the new LSx454

Thought I would start a thread dedicated to my motor swap. I am currently building a motor soooo out with the old 305TPI and in will go a LSx454 hopefully near Christmas time, if not sooner. Time for the fun to start

I noticed you haven't posted on here in quite awhile. Are you still proceeding with the swap?

Still working on gathering parts. I haven't really worked on it since pulling the motor, work finds a way to keep me more then busy.
