Good article! It's still to bad they had issues with the dyno since it would have been nice to have seen a dyno graph starting down lower in the 2k rpm range. I'm actually also surprised they used regular 5/16 dia. .080" wall PR's, and not larger diameter/thicker walled PR's.
I've then got to wonder how well that Crane cam 228/244 115lsa (+3.5~+4) would perform with a smaller 2.9L Whipple on a regular production LS3..?

I don't see why that cam wouldn't do well on a 2.9. I've seen much smaller and much bigger work great on ls3 headed 2.9 setup

It has a magnuson cowl hood that I've been working on to make it fit
It's still about an inch too low after reglassing most of the cowl
Might be cutting a hole in it
The lower manifold started life as a maggie manifold
Lots of machining later it has an aircraft heat exchanger inside and a whipple on top
Compression is only around 8.9:1 so the blower has to be spun pretty hard to make decent power still.
Should be around 800/800 on pump gas
