Greetings all.
Im new to the forum, but I have been the owner of my nada for almost 25 years. Unfortunately, it has been sitting idle for a VERY long time. I cooked #6 exhaust valve on a “high speed” run on the turnpike coming home from work with the back loaded down with tools, parked it in the barn switched vehicles and just kept working and here I am over a decade later in the process of uncovering it. Time files when your having fun I guess....
Anyhow, the frame although solid, had enough surface corrosion on the front rail that I can’t seem to make out the whole of the frame number in its entirety, I’ll try to get a better look at it as time goes by, but my engine is #S34300011A which I think puts my engine at #11? I recall talking to someone at RN decades ago when I was on one of my many parts binges that told me the “S” prefix means it was factory reworked. I used it as my primary work truck for a few years and it chugged along pretty nicely until that fatal run.
So while I'm uncovering the greaseslapper and digging out my factory manuals, I thought I would reach out to the community.
Haha Here I go:
1- Does anybody happen to have a source for the intake and exhaust valves or have examples to take dimensions from to make drawings?
a. I remember talking to someone out west years ago that recommended finding a motor rebuilder that did performance rebuilds and to have valves, guides and seats made from high heat refractory alloys to help hold up to the heat. Does that make any sense?
2- Is it worth finding factory spec or aftermarket gaskets or just make them?
a. Any known sources for quality gaskets would be appreciated.
3- Have any other engine modifications been done and tested that should be considered seeing as its being opened up?
4- Is there an NADA group on the forum or just this thread?
All for now.
Have a Great Day!
