I am going with 250 out of a 78 nova a T5 will go behind that.I have found a basic motermount that will put the motor right in my 53'it is avalible at Langdons Stovebolt,and then a basic crossmember mount for the tranny.Other mods include clutch linkage-dosent look to serious,water temp gage cappillary tube is to short-longer ones are available-possible cooling fan clearance problem,I think i will run a electric in front of the raidiator as a pusher. Good Luck Aaron
