I would not be surprised if you find another 40 hp with a bigger manifold and well-ported heads. Do you know what the flow nu,bers for a CNC ported stealth look like? Who has the best program? Last numbers I was given from a set were 346 at 7, 348 at 8. Exhaust were 229 at 7, 232 at 8. 2.14/1.81. 4.38 bore Whoa! I had no idea. My understanding was 320@.700. Thank you for sharing that info. They only claimed around 320-ish, so I have no idea where 340++ #s would come from... The last CNC Stealths I saw tested (Dwayne posted something about them in the last year or so) didn't even get to 320; MCH isn't doing the work any longer, so the additional blending & CNC chamber work that goes along with the basic CNC work to the ports alone isn't being done any more, IIRC.
