Carb Question, Drill and Tap Options

[bd1308]

I need manifold vaccuum ports, and I lack them.

I want to drill and tap for a fitting for vac hoses to attach to (IE head breather, etc.)

only issue is that I don't know what the carb base looks like inside....

does it have four barrels or is it open inside??

you all know what I have, the single progressive weber.....

"real carbs" cost around $1200 which isnt in my budget. this carb works really well...i'm impressed. i might ask my uncles that work at holley if they could score me some carbs tho. from louisville to dayton and back on less than a tank of gas....not to shabby. used to be a 3/8 tank from bowling green to louisville

Dual 40IDFs only cost $1200 if you insist on getting new ones. A used pair of carbs only can be had for $200 on Ebay all day long. You can usually pick up a complete setup with manifolds and linkage for under $400. Rebuild kits are $30 per carb, and jets are $5 a pop. If you shop carefully, you can have a complete, running pair for $450 or thereabouts. You can sell the single carb setup to some other yutz on Ebay for $150, so your net cost is $300.

Judging from the way the market has been going, these prices will only go DOWN. It appears there's a Chinese factory gearing up to make IDF and DCOE knock-offs, and rumor is you'll be able to get a complete setup with manifolds, linkage, filters, etc., and new carbs for $300 in a couple of months. The used stuff will only get cheaper as a result, as people won't pay THAT big a premium for Italian (or Spanish) made Webers. The price for a used pair of 40IDFs was $400 just a year ago. Now, it's half that.

All that said, you'd be better off assembling EFI with used D-Jet parts and Megasquirt...
