Cylinder Head Porting and Power Production

If you look close at the heads he posted you’ll notice they have very little swirl. In fact, much less than I use on my street/strip stuff and I really HATE swirl. It is a required evil sometimes.

If you also notice, the guy said he stuck his piston .080 out of the hole. Been advocating for getting the pistons out of the holes since right after HS. I’ve never had to go that far out, but I would if I had to.

Wouldn't high compression, raised dome and an optimal cam explain the "mysterious" low timing requirement and the high output of the one combo being bandied about? Seems the right cam with 11.7:1 could take huge advantage of the "supercharging" effect of narrow LSA and make for a stout combo while lowering the timing requirement. Would also take a very optimized chassis with perfect gearing and clutch/converter - still, there's no secret sauce there. Just a dedicated and talented racer.
