Interesting. It looks simple enough to make, but at $35 it's probably better to buy.
I wonder why Holley for instance doesn't make the flange on their pickup with a second bolt hole? Is anything fastened to the second bolt hole? I.e., wonder why it's even there. Looks like perhaps the second bolt may be hard to get a wrench on.
Also I wasn't aware that BRP had expanded their product line to 55-57s. I hadn't looked at their stuff in a while, looks like they have some good stuff.
The second hole in block isn't used for anything to my knowledge. My Ls1 and ls2 are the same as far as only using one of the holes from the factory.
here are a few more for 24$
