Pump Gas Non Stroked 340, 537 Hp

That's another big buck build. Like Moper says, I couldn't duplicate it for under 9K in this area due to the price of machining.

I also don't think that this engine would last very long as a daily driver with the low tension rings and high valve spring pressures, nor would it be very fun to drive with 1050 Dominator, but it would be fun on the strip with a torque converter loose enough to get over that odd dip in torque from 3000-4000 rpm. I'd imagine that would feel pretty funky when it was actually driven in a car. It seems odd that the article mentions that removing "X" amount of port volume did not hurt flow. That doesn't seem to be good for Indy and their CNC programs and seems to indicate dead air space.

Interesting point BJR in regards to associating the large valves with the torque dip. I would've thought it had something to do with the huge w-2 intake manifold combined with a 4 hole spacer. I was thinking that there was some type of pressure wave interference going on here. What's your take on my theory?

I was under the impression that the whole intake system from the carb on down to the valve should act as a funnel to increase velocity. It seems that this guy's mods throughout the intake system defeat this and may be the cause of the weird torque curve. There's no doubt that he got a lot of power out of his combo, but I think there's more than one way to skin a cat and it could be done cheaper and more efficiently with ported eddy heads, 108 LSA solid roller, 1.6 rockers, eddy victor, KB hyperutectics, Eagle H-beams, factory crank, Holley 850 HP. I bet it would get close (within 30 hp) and be easier to drive on the street although it still wouldn't be a daily driver getting 18 mpg.

Edit: Main caps 2, 3 and 4 don't look like stock pieces to me either.
