Not attempting to pile on here, but, going back to an earlier post by the OP...machine shop guy (not "engine builder") "calls it" a Roller cam...? Well, it's not up for interpretation; it either is or it's not. Lifters either have a wheel or they're flat, pretty simple.

If it's so rare, and in this day of EVERYONE having a phone that takes pictures..."machine shop guy" hasn't forwarded pics to salty?

And lastly..."pins in the crank journal"...? WTF? Main caps #2, #3, & #4 either are held in place with four bolts or not. Not a big mystery there either...

Theres a 61 1/2 ton floating around here with a 348 that was done 6 months after it was bought new, has papers from the dealership. Doesn't make it factory

What is the deal on the steering box he shows on the chassis? Say's h e has power steering, that box in 66?

It would use the same box , I don't see in that picture any of the power assist parts but they may have been removed?

Isky patented the cross bar solid roller lifter back in 1958--

Yup , was waiting for that , guess I should have stated it more plainly," Chevrolet" never did it, period ! And they had reasons for what they designed and that's the whole point.Anybody could put any cam in anything they wanted . So what I did too ? This conversation is about "factory" then it keeps going off topic. But "you could get anything you wanted back then" right ? Sorry I ticked you off before on that , wasn't trying to. It's my writing skills or lack there of, I should have explained my thoughts differently as to how that comment has become so over used and misunderstood. Let's wait for the stamped numbers, no ifs ands or buts then and all this back and forth will just be BS then !

We will just wait and see.

Did this get wrapped around the axle due to some miscommunication as simple as that?

Roller rockers? No.

"Double roller timing chain?" That's a much better possibility.

That I wouldn't know the answer to.
But I DO know the answer to "factory roller cam in a 327."

60-66--I didn't say chevy did it from the factory, all i said i did it, and it ran just fine with a power-glide. You are the one that said that combo wouldn't work together. That's all i was referring to. Have a nice day people.

I said we wouldn't get a pic of it. No surprise there.
Who wants to give odds on the engine stamped VIN?

[Sweeney]

While we're waiting...I don't have a SPID tag in my '65 glovebox...?





Did previous owner peel it off or was '66 the first year it was added? I'll take my answer offline...thank you!

I've been a member for a good while and have never seen a thread like this, so it seems like the perfect time to pitch my new Webinar: How to Gain Credibility, Get People to Listen to You, and Make Friends on the 67-72 Board. For $19.95 you'll learn to master the following topics:

1. WORD CHOICE: Call people stupid and liars. Use those words when describing other members as they will honored to be associated with them.

2. TOPIC CREATION: Never search the forum or check the 60-66 FAQ Index before asking a question. Who cares if what you're asking was a topic yesterday, twice last week, 5 times last month, and 208 times last year?

3. TECHNICAL SUPPORT: When someone can't figure out something or makes a misstatement, make sure to belittle them. This will make you look smart since you are above their questions or providing helpful advice.

4. TECHNICAL SUPPORT, PT 2: When given advice, ignore it and keep posting more calls for help. If you should actually figure out the issue, don't post that it was fixed nor how it was done because we all enjoy a good mystery.

5. TYPING TECHNIQUES: Don't use punctuation, proper grammar, nor spelling, just capital letters.

6. MOD HELP: Don’t bother reading the Forum Guidelines and Rules. The mods are there for a reason and creating extra work for them is appreciated.

7. SMALL TALK: Be a troll. Comment that something “SUCKS!" and then just keep insulting everyone.

8. ADVANCED SMALL TALK: Always point out that your opinion is correct because: A) Your number of posts is higher; or B) You’ve been a member longer.

9. THE BIG PICTURE: Never treat anyone with any respect whatsoever. You'll never meet them face-to-face, so it doesn't matter anyway.


Email cash only ... and don't forget to tell a friend!

Your not going to get any pictures. Salty has gone and will probably never come back and share anything with us again. Can't say I blame him.

[The Rocknrod]

On a lighter note it was just "verified" that my 64 came with an LS6 engine from the factory.
That's funny right there.
I wouldn't either if I were called on those claims. As was said many times it's not like he wasn't given the opportunity to walk back the statements a few times.
That's not anyone's fault on this forum.

I'm usually in the 67-72 forums, but got bored and went here. Interesting thread. My suspicion is that he had a timing chain replaced at some point, and the shop put in a roller chain, like you mentioned. It's going to be interesting if the engine comes back stamped like something that did come from factory with a roller cam (as in it would not be the original engine). Machine shop guys (well, anybody) can do strange things, sometimes.

As for the vacuum gauge, it is a tool for getting better mileage, as you can watch it and keep the vacuum in the big numbers (with a light enough foot).

I don't know that much about this vintage of truck.

As for the "65-1/2", I'd have to say that since the Changeover happens in the summer, with new vehicles typically rolling off the assembly line in late August to early September, a person could be confused and think it is such, where it obviously is just the new model year vehicle.

Ok, pardon my ignorance, or lack of experience on this issue, but aren't those stamped numbers on the front pad of the block often wiped clean during a block deck / rebuild?

Often? I would say no . I spent 20 years in an automotive engine shop here in Wisconsin and at that time most of the engines of this age did not need decking. That was determined by the customer or by how bad the block was .Common rebuilds just didn't need decking. If this engine is decked then there's still a few possibilities as to telling what it is but even less credibility as to Saltys claim. Ya kinda have to back this claim up with something. If it's out of something else and transplanted into the truck it will be obvious with the Vin stamped in it or still have the broach marks with nothing stamped in the deck. I've seen several over the counter blocks in the mid sixties with blank pads.

I have never had a block decked, if someone decked an L79 block they basically wasted a piece of history. It would be like decking a 65 chevelle SS 396 block, one of 116, it would turn it into a block of one of 1,000,000.

Right.If you got a service replacement block, it would fit so many applications that stamping any sort of info would be useless.

Thanks for posting photos of your excellent original one owner '66 salty531. You just happened to buy one of the most desirable models in the '60-'66 series. You deserve a lot credit keeping and preserving this truck over the years. Lets not spoil this little gem on just over what a shop person claims to have, photos will resolve that issue. I believe in the end, it will all boil down to miscommunication. Brad54 hit on the double roller timing chain, which may be the real heart of the matter. The 327 option in '65 and '66 pickups was a modified truck engine not a car 327 engine. Most mechanics are car engine mechanics, not truck engine mechanics and may not be familiar different features. Photo of timing chain from '63 truck shop manual. Mid year '66 offering of the 327 in C 10 from engineering manual. So, it would be logical this C10 was special ordered in '65 with a 327 (220 hp version used in '65and '66 C 20-30's ) because it wasn't available as a standard option at that time. Please check out the "most original in existence" thread , http://67-72chevytrucks.com/vboard/s...+existanceyour your truck should be added to it!

[salty531]

I don't know if i will ever be able to resolve this issue but i am telling the truth and am as puzzled as all of you. I just came to this forum to see if i could get some answers. Obviously that is not going to happen. The truck is going to be restored and kept in the family. I worked as a parts man for a Chevy dealer in the 50's and saw many strange things come out of the factory so i believe this could have been possible. I have a set of the original shop manuals for the truck which does not help. This machine shop person is very knowledgeable with Chevy engines. He may be wrong but i trust his word.
