New guy with a 440 swap
NICE START! Feel free to check out my build putting a 383 into my Demon, for inspiration and tips on what it takes haha - this is my first time doing a BB swap and it's been a super fun pain in the *** hahahahaha
A friend of mine is running C body cast manifolds in his Demon (400 not a 440)
I also installed a 68-70 B body 8.75 in my car as well.. I see you have a TON of room between the rad/ motor unlike me - I have Trans-Dapt swap mounts though so that is likely the difference..
Now that the engine compartment is clean, get a couple cans of the Yellow over cleaner, it will strip that rattle can black paint off, and leave the original paint..
