tunnel ram update

Yea it does but I’m going to be honest up front and say I don’t know what it could be. I’m asking questions for clues that may POP up and say something to me.

So far, the way I would have done it would have been more gear. This may or may not be a part of the problem but IMO not the single soul guilty party.

You also have a lot of carb on top. The 340 AVS carb is rated at 630 cfm by Carter. So that be 1260 cfm. And that’s a lot of gobble gobble! LOL!

IMO, it is also more cam than I would have used for the combo and a 4bbl. (Except a manual trans car.)

I’m wondering if the slightly low gear coupled with a ton of W.O.T. cfm is creating a momentary stop of airflow (metering issue with the OE carb) and your having trouble getting everything moving again. This would have the carb go rich lean rich lean rich lean until the engine can injest it all.

I do think that this thing (via your description) runs like crazy with long legs. It’s gotta be pretty good on the street!
