Okay, some of you might remember that last summer I swapped out my stock intake for an Edelbrock performer rpm airgap on my 454 mag. I couldn't get it to sit down in the valley- it was hitting the cast lip where the valve cover sits. Several trials and lots of time on the grinding machine to grind the casting bosses down, I finally got it to sit down. Then the bolt holes didn't line up very well. I squished it down anyway- and after two runs, found out the oil looked like a milkshake.

Well, last night after a few beers in my brother's garage checking out the tunnel ram dual-quad setup he bought for his jetboat- he noticed the casting bosses were ground down too! It clicked... we now think the intake was for a tall deck motor- but checking with the catalog, they only make a std deck manifold for that catagory.

So now I'm thinking I'll change the intake to something else- what should I get? I was thinking about a merlin or dart single plane.
