I’ve researched this issue online for over a week and can’t seem to get a solid answer other than I need a stock intake. I have a 1970 440 rr clone with the stock rr hood. I purchased an oval air cleaner and trying to find a low alum intake that will allow the cleaner to clear the hood (note not adding air grabber setup). I know my current Edelbrock RPM is way to tall. Has anyone successfully done this with the CH4B? Performer? Holley SD? Other?
