Magnum intake restriction - 04/16/21 03:13 PM
This is my first post so I hope it is in the right forum. Used to own a 94 ram 1500 shortbed that was lowered and had the 5.2 in it. Best sounding truck I ever came across. It had headers and a cat back that I never was able to identify along with a big block 50 flow master. Also had the MP ecu. Never got to do some of the things I wanted to do to it as my son totaled it out and I have been without a mopar since. Onto my question.
I know the stock intake manifold on the magnum motors is much maligned. Part of the problem I see is the opening to the ports is shrouded by the close proximity of the plenum plate. My feeling is if there was room to install a spacer that would move the plate away from the intake ports it would allow more air in and they would flow better. The spacer would have to be cnc machined and if it was only an inch thick it would be a huge improvement. I'm just not sure if there would be room without interfering with the pushrods.
I wanted to throw this out there and see what people thought about the idea.
