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.
Yeah i dont think you'll see 340+ cfm out of a 2.14 Stealth that is remotely affordable. Call the numbers however you want but ported you'd do REALLY well to get over 700 on a decent motor build similar to this.
