Questions - 1969 Stepside

[bdmcgee]

I just got a 1969 GMC Stepside. . . about 2 weeks ago (posted some pictures today) and I have lots of questions as I start to work on this bad boy! Some of them will be fairly basic. This is my first "project" vehicle, but honestly, this truck is SOLID and only needs minor changes - like a new wood bed and new interrior. Anyway, here we go and THANKS in advance guys.

1. I've been told NOT to run syn oil in an old vehicle. For the life of me I can't figure that one out and when I changed the oil, I used a blend (whihc I use in all my vehicles except the bikes) Comments?

2. Lead gas. . . Is there a way to tell if an engine has had the valves harden? I've been running an additive as a precautionary. Unfortunately the guy I got the truck from, was a "collector" and didn't know much about the cars he stored (had some great looking trailer queens though)

3. I'm not restoring my GMC to 'original', but would like to add the correct badges and emblems. . . Was there a "GMC" across the front of the hood? Was there a "engine size" on the front fender? I believe the truck is a Custom (the glove box has "Custom" on it) Should there be one on the doors?

Thanks very much guys. Any help would be greatly appriciated.
