Holley/Demon Carb stumble

Cudafever said

Yeah im continuing on with this package but it far from a matched package. The Demon metering block is the odd man out at this point, and need to buy some metering block that work with a Proform main and base. And i think i'm going too.
The problem is i can buy a standard set of primary 3310s........(gamble with porosity)Or a billet blocks that i can put a 3310 tune into??????

Why do you want a 3310 tune? You can buy some ProForm blocks for cheap. Use a simple two emulsion set up with the IFR's in the low position and tune from there. It would be much more simple than what you are doing.

My cousin almost bought a Demon carb at a swap meet last winter. Fortunately he called me before he did.

I found him a used ProForm 750 for 450 bucks. Cleaned up the tune up by using just two emulsion holes, opened up the power valve channel restrictors by about .010 and put is some T slot restrictors.

Now he is golden. He can make small changes and see it on the plugs. Probably needs to do a bit of tweaking with pump cams and squirters, but he's 99% of the way home.

The point is there is no reason to reinvent the wheel.

I've never been a fan of the 3310 for anything. I'm certainly in the minority but I've done enough dyno work to know they ain't for me.
