Thanks again for the great info.
I'm having fun learning and picking up parts for the one I don't have yet. Don't they call that "putting the cart before the horse"?
Oh well, it's what makes my little world go 'round some days. Always been car crazy, and these truck are a "new" endeavor for me.
I greatly appreciate the willingness of you guys to take your time to share your knowledge. It's really awesome.
Now, if one of you kind gentlemen would just send a nice clamshell rear light my way........................ Lol

Found a few civilian 302s and a couple civilian 270s. Going to buy at least one of each. Same guy was a GMC enthusiast for many years. Used to haul pulp with the old trucks so has some larger vehicles, also a larger school bus, etc. etc.

302 engines tend to appear in spurts. I recently bought two of them, and a guy I know bought a really good one recently. However, it had been a long time since I had seen one for sale reasonably. If it doesn't wreck your budget, I would buy several. Especially heads because they are prone to crack.

Whatever happened to the rumor about the "new in the crate" military 302's that were available, supposedly produced to power DUKW's? I heard that story 5 or 6 years ago, but it seems they were a figment of somebody's imagination!

I heard that rumor too from a drag racer who runs 302's about that long ago or maybe longer. Nothing since so one must consider the rumor mill as accurate as always.

I heard that rumor at one time, but i didn't really think too much of it at the time. The military sleeved a bunch of the 302 engines back to standard so it wouldn't seem that they would produce crate engines. I had one of these engines some time ago, but I traded it for something else. 25 years ago there were a lot of 302 engines to be found in 450 series farm trucks that were still standard and didn't have the hump to be ground of to put on a starter. I even still have a NOS short block that I never have installed. I've had it so long that its kind of like someone told me not long ago, "If you build a motor with it, its no longer NOS" I wish someone would come across a stash of NOS heads. NOS military valves for a 302 come on eBay ever so often. But I never have seen a military surplus head. Maybe they welded them when they sleeved the blocks.

Bach in the early 1950's a lot of milsurp 270'a were used in dirt track race cars. They had so much torque the flathead Fords were halfway down the straightaway before the Jimmy-powered cars got the wheelspin under control coming off the turns.

There are a few available, and a couple or so 270s. What parts on these engines are variable if engine no good. I heard that exhaust manifolds crack? Also, heads crack? Any other reason to pick up parts engines?

Heads are the most vulnerable. Exhaust manifolds are around. Lots of guys put on headers and have left over manifolds. Heads can be repaired, but I prefer one that hasn't been repaired. We used to refer to GMC heads as glass heads.

don't let anyone worry you about gas mileage. I have a supercharged 270 and get a solid 16 - 17 mpg on the high way and I like to stab it now and then. Also talked to a guy from northern WA. with a 302 with 3 carter Webers ( stove bolt eng. co. )and lots of other goodies, all in a 39 coupe. He said he was getting around 19 mpg and he was pulling a tear drop also. If I were you I would bump the comp. up a little 8.5 - 9.0. use a small port head if its just a cruiser. Headers and good carbs not the old stock dribblers. then hook it to an overdrive trans of some kind t-5 or 700r4. you'll have one nice driver that won't look like all the others. I really dig the old suburban's
