Always nice to see how big brother is doing.

Interesting, no piston work? Nice log BTW!

Thanks Lizard!

Very Nice Special-tool. I like the intake design. I may steal it for my own.

Hey, that custom hood prop device looks just like mine. You didn't happen to buy it from Vinnie, did you?

Ha - yeah I have a sliding prop rod that slides along the strut brace (like the BMW CSL's I stole the idea from).
I haven't put the brace back on because this manifold is 3/32" taller.

I like that last pic. Your daughter dialin' in a little more boost?

I'd like to see more pics of that plenum off the car if you have any.

You've got mail, counselor.

She was adding a little advance to the idle cells.
