Thanks for the info.

It'll help.

I wonder if it would be advantageous - he asks after having not crawled under the dash for a long while - to remove the threaded piece and use a bolt & nut to pull the cowl eyebrow in.

I need to get back to working on the 31, but right now am making an oil baffle goody for the 32 using the 31s engine for a pattern.
Dawned on me a while back that I could do that instead of tearing the 32 down for a week or so.

Make the goody on the 31 and have the 32 down for only an afternoon for the install.

I think too that I've figured out an improvement with the Buicks one piece sheet metal intake manifold gasket/bathtub that keeps oil off the intake bottom and assists in keeping flying oil droplets under control.

Dang late model Buicks - 430, 455 - have the valley open at the bottom so most of the cam is exposed.
