Leonard,
First the easy part. Here are the 349 and 371, 8.2 deck dyno sheets. Ted gave me the most recent 371 which had our hydraulic
roller option and made about 25 HP more than the standard build hydraulic cam. So I'm sorry it's not apples to apples. We are finding the hydraulic rollers are very popular options across the board.
To clarify about the LS style reference, here's what I meant to say.
The 200 and 235cc 18 deg. head was born with chamber design features and placement developed from our Warhawk LS program. The ports are reworked developments of our previous Windsor design, and the standard Windsor angle of 20 deg "rolled" to 18. The port locations are stock, just bigger and reshaped. These have shown dyno numbers exactly equal to our previous CNC "standard" 200cc head up to 6000 where these improve by 13HP to 6300. The Drag version above proved that they love RPM because up to about 7000 they pick-up 40 more. So they love to breathe.
The true LS influence is found in the 10 deg Man O'War (not yet in production but proto testing). These are 275 and 285cc runners which are directly from our LS program. They have highly raised ports (compared to SBF aftermarket) with a pronounced angle change to 10 deg. These are currently only for sheetmetal intakes and big boost. Indeed, we've seen 440cfm on ported versions we've done, which is more flow than our ported 350cc Merlins!
All of this is on-going development, but the "Sportsman" ported set on the Drag version is now a readily available option.
By the way, the 349 and 371 sheets show the "standard" CNC head which is being replaced by the new Man O'War line.
Confused yet?
