Yep, my TQ on a 318 stroker bogs all the way to 12.6 - and thats a NON reco carb, with 40 year old floats and bowl - and there's more in it.

On topic - I have hogged out both an LD4B and an LD340 successfully - an air gap should prove no issue either.

(PS - Don't listen to what some "others" on other sites have to say on this issue - they're yet to prove to be able to run a qtr time, let alone know what can and can't be done with a TQ and a 4B or LD........listrn to the Demon .)
