We have not had an exihibit @ PRI in a few years. We do advertise in the mag for the show issue with our billet main caps. I would like to do a booth again someday but I think I will do the Ft.Lauderdale boat show next, when the time comes.

Use Permatex black 5910 silicone. When you lay your bead make certain to push the silicone into the corners where the block and head meet. Do not use the end seals. I run a good Moroso style push in breather that will allow you to run hoses to the flame arrestor. Valve covers should have good baffle on inside.

Because it was the best intake at the time the engine was designed. It is also the stock merc intake on the 500HP engines. People have tested darts and they do give up a little in the lower rpms, but make a little more in the 5000-5400rpm range

The RPM airgap design is only about 5 years old and was not even an option. Its newer technology and the air gap design is comparable with single planes, but gives better lower rpm torque.

Okay.

Just very weird.

Swore I heard the same exact intake manifold deal on same race class while I was there. Same head deal too. This was almost word by word. You sure you weren't there and forgot ? Damn, maybe you where cloned. This is just too uncanny. LOL !

Oh well. Guess many people end up at the same place even if they take a different highway.

Use laquer thinner on the block and intake surfaces and let dry before laying down silicone.

I'm finding better results having a high quality 4150 intake with 4500 carb then a 4500 intake on these type engines + stronger ones. The transition between carb + intake is important.

I even got a call from SAM (School of Automotive Machinists) the other week to send one of these down there.

Yes, the transition is terrible in most setups, and makes a big difference. I've got plenty of clearance in my setup, and have been wondering what to use for the transition. Is that a part you made? Are they testing it for you? I'd be interested in the results.

Has anyone tried the new Merlin X intake ?
