All good info here. Sorry I've not been around to participate recently. Busy, busy with work (military aircraft/warfighter support). Anyway, I'm about to get moving again on some of this work, I need a new rear for my '86 longbed, and am looking at a late model rear with discs and an LSD rear in it and just changing the mounts to simplify things.
I still have to do both ends of my '87 shortbed, but first I'm pulling the /6 out of it and putting in an interim 318/904 combo.
While I was up in Indy at Indy Clylinder Head's indoor swap meet and trade show last month (my brother bought a full race 408 for his '72 Scamp from them) I finally saw another truck using an idea I had some time ago: they had the early '70's flat Dodge truck hood, that has recesses in it similar to the '68-'69 Road Runner hood, and it loos so much better than the later hoods with the raised prow on them. So, I lucked out and found a perfect older hood, which I'll now make a tool off of so I can produce them in carbon for both my trucks.
