Convert to replaceable idle air bleeds?

I don't think I have that level of drilling/machining skill...

I'm thinking of just buying a billet primary metering block and tuning the idle, cruise and moderate acceleration... then get a secondary block later (Proform catalog says their block will bolt on to a 2-corner body, although the idle screws won't work). Your thoughts?

you could, there’s a few different was to go. A QFT plate would probably accomplish the same thing on the secondary’s. Depending how radical the engine is will determine how much adjustability it needs.

nevermind, just seen it’s a pumper. Yes you could add a secondary block with idle screws. Like you said, they just won’t work. It’s worth the effort to mod what you have, if you screw em up then spend the money on new blocks.
