I'm finally close to the end of this 318 to 440 swap in my 73 Roadrunner but it's fighting me. I say 318 to 440 swap but really it's a complete drivetrain swap including the 440 I rebuilt and a 727 trans I also rebuilt as well as a complete front end and suspension rebuild. The engine is a 440 bored 30 over with speed pro six pack pistons, comp 284H nostalgia cam, Edelbrock E street 75cc heads, smith bros push rod's, PRW steel 1.6 ratio rockers, all running on Edelbrock E street Efi and being cooled by a champion 26" 3 row with a shroud and 2x12" fans also being controlled by the edelbrock efi system. The trans is a 67 727 I rebuilt and installed a Transgo TF2 shift kit and I also installed a mid 70's valve body in as the original had cracks in it. I used an A&A transmission 26-2800 stall converter per their recommendation. The first of the issues I've been dealing with is heat. The engine seems to run pretty hot and by the digital gauge in my edelbrock efi it runs from 203f to 214f and this is with straight water and a 195f thermpostat. when it says it's 214f it seems very hot and underhood temps get high as the efi has registered that it was too high at one point though when I took a picture of the factory guage at the same time it registers normal. The other main problem I'm running into is the trans shifting. When I set the TV cable to have the lever full with full throttle it would shift 1st to 2nd perfectly but would never shift to 3rd. I loosened the cable a bit and I can get it to shift to 3rd now but I have to be easy on throttle then left off gas when I think it should shift and it does but if I'm on it it never seems to shift. I've been battling these problems and it is really starting to get frustrating after a month and a half of working on the car every free moment lol.
