Kurts gotta be talking a 77mm...those things are huge aluminum meters but it was the go to meter years ago until the plastic 80mm came out. I'm also not a fan of the lightning meter on anything....
Cam could go a few ways personally.. comp 35-552-8 I like
This is the closest one to the one I have. Mine is flanged and has a slightly different sample setup. It was a Pro-M before they went out of business the first time. Then it was PMAS, and I think they are about of business now, and they have started up Pro-M again. I can't keep track.
I have heard bad things about the Lightning MAF, but I defer to Rick on explaining it because he is more familiar with it. That intake has definitely already been ported.
