I've got a few performers and a cool nos Elgin/prostock. Did you ever make your trip down to So Cal? Still interested in that trans if you still have it.
I'd like to see some pics of the manifold as well. I've seen Prostock on some other engine parts (mainly valve covers) and and know Dema Elgin who has been making cams for a lot of years up here in the Bay Area (now living in the wine country I believe). Curious if they are tied in.
Still have the trans and no, I haven't made my way to SoCal yet.
