Magnum intake drilling plate project

Correct. Either Eddy RPM air gap, or Chinese knock off air gap. Mopar performance made a nice dual plane (non air gap) and a single plane, but they messed up by making them too early, meaning magnums were fairly new and nobody was swapping them into older vehicles. Mopar got out as sells were down, so we have our two choices - unless you drill :) I asked Johnny Mac to make a nice dual plane (non air gap) that sells for 200 bucks, and it would go. More magnum swaps than ever, and not everyone wants a air gap

Hey you for got one. Lol indy cylinder heads makes a single plane for magnum heads. I have one on my 2000 360 magnum. I lucked out and bought mine for $300 shipped brand new. I think they are over $500 now. At the time I was wanting to buy a mopar m1 magnum intake. But every one I found was listed for $600 or more. So with that said I hope the OP gets his plates made. Best of luck to the op
