Hey guys... New to the form, I shall introduce myself shortly. Here's what i have going on. I have a 66 chevy caprice, with a 327. I can't see the numbers on the back due to linkage and some guard thing running under it covering the block numbers. I can however see the numbers on the bad, and I can make no sense of them. Here is what the pad reads " TII0IHC". Those are all thats on the pad. They do not match my vin, so i'm lost. Any thoughts are appreciated. Thanks guys
Those won't match your vin. T1101HC is Tonawanda Nov 1...HC is a 327 275hp...but not coded that way in 1966. Should have a letter after like HCR the R for Rochester carb. I googled it and the HC was used in many years by itself...so could be out of a 1965 car if there isn't a vin number as I don't think they were doing that till later..like 1967 I believe...
yeah, the partial VIN stamp on the block started around 1968, I think. The number you have on the engine is what we would expect to see. My books show that HC is indeed the correct code for a 66 chevy full size car, with the 275 hp 327 with Powerglide.
Thanks so much guys. I'd****ume not have the R for Rochester makes sense, considering it has a carter Avs on it? This car was passed to me, and I know it's as original as original gets. I guess I'm just trying to make 100% sure if I should ever sell it.
The only way you can make sure is to get the casting number and casting date of the block to see if it is for 1966. I've seen numerous Google hits showing HCH and HCR for 1966....no regular HC codes..but who knows?
Now that I kinda understand, I looked up just the HC. Seems from what one site is saying "HC" was on 65',67', and 68'. Also have one for a 350 4barrel m/t, in 1969.
As was mentioned, if you look at the casting date in the back of the block, you'll know for sure what year block you have. You can also look at the casting date on the intake, and pull the valve covers you can see what the heads are. Also look at the body tag on the cowl, it should have the body production date (letter/number), if that is also November 65, then it's probably the original engine.
In '66 and '67 only California cars were required to have the smog equipment, that's what the 3rd letter denotes Holley or Rochester carb. Because they used different carbs for the AIR system that was required for California cars. They can be found coded either way. Especially the early '66 cars, beginning in '68 the smog law was nation wide and they all had it, so the suffix was universal again.
It can be hard to see the casting numbers on many cars with all the***** in the way sometimes. Use a digital camera or cell phone camera and take lots pictures of the block behind the drivers side valve cover. Keep taking pics until you get a good one. If it's dirty you might have to reach back there the best you can and clean it first.
I've been using the camera trick too...lately i've also been using it to take pictures underneath cars I'm looking to buy...beats laying on the ground...blowing up the pictures is great for my now weak eyesight...resisting bi focals big time...lol
I will try that on the back of the block. It's a narrow gap so I may have to remove some things. I did code the intake man, and it's correct for what I should have. Not really sure why I'm chasing this dragon. I'm the second owner, and have no intentions of selling the car. Maybe I'm doing the foot work so my kids don't have to?
Take a good look at that carter carb. We had a 65 impala 327 275 hp with a factory carter. Rebuild parts were very difficult to find, ended up getting an New Old Stock kit and after rebuilding it didn't last 1 summer. Ended up swapping an edelbrock on and putting the original carb on the shelf. They're nice cars, hope you hang onto it.

Pretty odd that the tach cost half the engine upgrade and that the destination charge was a whopping $14.40.
