The fully counter weighted billet crank, reinforced billet pistons and dry sump went a long way in fixing his issues. Said he could have went without the dry sump but did not want to go through all the building and testing with the potential problems with a high end wet sump.
I thought it was now pretty much common knowledge that a Pontiac needs a fully counter weighted crank to make big power-big RPM. Especially NA.
Or you will have main bearing issues just like Brian said.
What Pontiac folks could use is a forged fully counter weighted crank like the BBC guys have for 900$. Pontiac guys would pay 1500$ for them. But the dies cost 150K and you have to wait 10 years to get your money back.

Sound like Mike just threw money at issues like i do or so i heard. Lol.
Mike and I shared quite a bit of info and both of us experience similar issues on some things.
