Default 427r
I have one in my Backdraft. Went with it because I didn't want to have mess with the fuel injection. I am very comfortable working on Holleys. The engine has a serious lope to it at idle. Sounds like a muffled funny car. Does not like to be below 2k rpms. Very powerful after that all the way to over 6k and it gets there very fast.
