Quote: What factors about the way the engine is built decide if a tunnel ram is a better choice over a single plane intake and one 4 bb carb? I have a 493 at 12 to 1 comp with OOTB Indy SR's with a comp 262 575 with 1.6 rockers, plenum ported Victor intake and 1050 Dominator. Would this engine benifit from a TR?
I bet you'd be at least a tenth quicker with a tunnel ram and the right carbs. Carbs are key, I ran two 750 Quickfuel tunnel ram carbs and they were perfection right out of the box.
