4412 or Quadrajet question

[Hobby Racr]

After few years off from racing I figured Id try it again. So Im building a new hobby stock motor over the winter 355 chevy flat tops camel hump heads. Or rules will let you run a 4412 with a torker2 manifold. Or stock cast iron( sorry no marine intakes) with the quadrajet.

Which one would be the best combo to run? I do plan to spend the money on a built carb no matter which combo I choose. So would a q-jet be better or the 4412. Also are there better flowing cast intake besides the marine to combo with the Q-jet.

Thanks

Q-jet with an internally modified intake, block the heat riser. Way better then a stock 4412.

I have a perfect motor for this its got a stage 3 quadrajet and its a 350 block with a 4.00 stroke has all good parts and pulls 15 lb of vaccum. Call me if your interested or want to know more details 740-707-5360.

quad can flow 750 cfm,..some up to 900,...4412 limited to 500,...ant to hard to figure out witch will make best power...

The difference is bigger than that. Don't forget 2 bbl carbs are measured with 3" of mercury vacuum to see 500 cfm...4 bbl are measured at 1 1/2" of vacuum...If you measured a 4412 at the same vacuum, it flows about 375 cfm vs. 750 for the Quadrajet...

How about the intake for the Q-jet. Does say corvette intake or Camaro intake out flow just a plain stocker say from a truck or they all pretty much the same?

Check with Stock Car Driver. He's posted an intake number on here that tested well a couple of times.
