I've got a 68 Dart w/ a 225 slant 6 w/ a one barrel holley and I want to switch to a 4barrel edelbrock w/ Clifford 4 barrel intake manifolds and I'm trying to find out how big of a carb and a cam I can put in her without blowin it.
thanks

Best suggestion I can make for a basically stock engine is the 1971-77 244 degree .406/.414 MP PN#3512639.

If you like Holleys, the 390 CFM 4 bbl is a sure bet. I've run them on 4 & 6 cyl engines. If you prefer the Carter, the 500 CFM is a little larger but also a good choice.

You can get 2 and 4 bbl adaptor plates for the Clifford intakes. You may want to consider a 2300 Holley/Webber 2 bbl for starters, and then step up to the 4 bbl later. I had one of these on my 74 Vega. It's a decent carb. Just a thought.

Later,

I may have goofed on the "2300" model number on the Holley/Weber. Checked the Summit catalog, and that's what they list for the 500 CFM 2 bbl.

Sorry,

The Holly 2300 comes in a 350 cfm version, I have run these on a slant and they work well once dial-in.
(I had to increase the pump shot and the power valve rating to get a lean transition into main feed "stumble" out of it)

i had no idea that holley was now afilliated with holley. weird. i had a buddy who bought a weber DGEV progressive two barrel (from clifford) that was an awesome street carb. i ran a 350 holley on an m-1 intake and never cared too much for it. it ran ok but always seemed like it was too much for the street. the 390 four barrel always seemed a much better choice (only 40 more cfm thru 2 extra venturis.) 225 inch motor doesn't require much more air than that.

We have a new product at Clifford Performance!!!
The Weber 44 IDF 530 CFM 2 brl. now has an adaptor for the Clifford Water Heated Intake Manifold. This has just come out of the Blueprint
Department with the new 08-1044 Carb adaptor and Weber 44 at $399.00 + Adaptor at $68.00. 909-303-2333

This will rip the Holley or the Edebrock because the 6 Cyl. engine needs more air than gas at higher RPM`S.
Thank you --Larry
