And what new intake? Tracy's ported IM?

LOL - ok. I'll keep the math simple.
If we do ricer math we should make an additional 300 rwhp from the cams alone!
Tracy has a new pattern in the intake called a "golf ball" pattern. I remember hearing years back when I think Titleist added two dimples to a golf ball and the ball flew further than a ball with standard number of dimples. It was enough of an improvement the ball was banned for a couple of years.
It had to do with smoothing the air flow against the surface of the ball to create less resistance. I'm guessing on this but if the same type of pattern were applied internally to a runner in an intake, it would create a micro turbulence against the surface of the wall and smooth and compress the air toward the center creating a faster air flow. Like I said I'm guessing but is is an interesting concept in theory. I'm trying to get Matt to send me some pics and maybe I can get a better explanation at the TCN this weekend.
Similar tricks were used years ago on carbed engines where the intake runners were left rough in certain areas creating turbulence to keep fuel atomized in the intake runners and solve the problems of fuel literally puddling in the low spots in the manifolds. Since the LLT intake manifold and intake ports on the heads are dry, the trick is to manage airflow not just create big ports and runners.
Back in the 60s and 70s, Chevy had heads on small blocks which had 2.02" intake valves, for short track and drag this was the hot setup. Chevy Vortech heads came out and the intake was 1.94" and the new heads increased the velocity of airflow by using smaller diameter runners and a special design in the runners.
Should be interesting to see the complete package.
