Re: Engine Analyzer and Drag Analyzer.. Willing to put your info in.

Rip,

IMO, I'm not sure a dual plane would help much, here is why..

The converter he has in it should be getting him far enough up in RPM to where the low end TQ isn't going to be a big issue.

The heads he is running have a 260cc intake runner and have a 2.165 intake valve. Paired with a small cubbed motor, it hurts TQ even with a small duration cam. A duel Plane might help the low end TQ, but over coming the low velocity air flow in the heads is going to be a hard thing to over come.

The L92 heads he has on that motor don't seem to like real big camshafts until there is a lot of cubic inch or stroke thrown at them. A 362ci motor is only going to require soo much air. The L92 heads flow well in to the 320CFM range stock from the factory, but at a lower velocity. I think that combo would be better suited with a different set of heads personally.


Here is an overlay of his current combo with a typical single plain vs a dual.






Here is an over lay of the existing combo with the L92 heads vs the ones that are on my motor. Easy to do since I have both head profiles saved. Mine only flow 306cfm but have a much smaller runner and only a 2.02 valve.
