I just came across an OHC-6 and some OHC parts. Can anyone ID a 9782229 cylinder head? Worth buying (cheap?)

Vikki, that is a '66 Sprint (4 bbl) head. The Holy Grail of OHC, it has the smallest chambers and the most flow in stock form of the OHC heads. Worth buying cheap? How cheap? (I won't put in my personal bias that all OHC parts are worth buying!)(Oops!)

Going to email...

Okay, so now I'm officially an OHCer, and it looks like I found some good stuff. However, I don't have a CAR to put an OHC in. So I'll put together a list once I scrape the grease and grime off

Be careful, there's something about touching one of these ......

Maybe, but big V-8s are pretty addictive too..

You could put in my car

I heard one of the announcers of the Barret-Jackson auction mention the PMD OHC. A Jaguar was on the block and he mentioned the Pontiac as a good engine for it, and that many American Jags of the day swapped out for it.

It seems there is a whole lot of information available on many sites for Pontiac V-8s, is there a set of charts for block codes, head codes, manifold and carb codes for OHC-6? Otherwise I can collect all the numbers and still not know what I have

They're scattered in various places. Many can be found on the OHC site, but their search function is kinda lame. I have some #s but not with me. I'll get a few posted if I can.

I appreciate the help.

Block (letter located in front of #code next to filler tube)
ZN=230/250 1bbl auto
ZD= 230/250 4bbl stick
ZK= 230/250 1bbl stick
ZE= 230/250 4bbl auto
ZH= '69 250/230HP 4bbl 4spd
ZC= '69 1bbl stick
ZF= '69 1v auto
ZL= '69 4v auto
I dont know how to decipher the block #s after the code. As you can see, some of the letter codes can be a 230ci or 250.

There are some 703____#s for A.I.R. systems, found in parts manual.

The ? marks are from known memory lapses or unsure things. Some others may be able to correct some of my mistakes or unknown memory lapse

Very cool, thanks! I'll be going to pick up my engine in about an hour.

I changed some things in the above posts. I found this website to be full of invaluable info.

Well Vikki, Don't keep me guessing! What did you find in the way of OHC 6 parts?


Rob

I found a cache of potentially desirable but condition unknown OHC goodies. TOHCan is helping me sort it out now.

From reading the posts and looking at your pictures: You look as if you may have found yourself a fairly complete 66 Sprint engine? Good find! (would the cam happen to be wiped out?)For some reason I only find 67 model engines?.....

cam looks perfect as far as wear, but shows a lot of rust. It's an A cam, so it looks like I have a mix 'n' match engine with a ZN short block.

I'll post what is usable/recoverable/available soon! I'd like to keep it, but you loyal cammers can do more with it than I can.

Howdy
Vikki sounds like you may not keep it. If so I would be interested in the Sprint head. Just let me know here or e-mail me.

Good news, I vacuumed and wiped the gunk from the bores and off the pistons, and find the cylinder walls to have a slight but noticeable ridge, and no more than minor scuffing on the walls. The crank turns over easily by hand and the pistons reciprocate nicely. #1 appears to have a worn or broken ring as the fit is a bit loose, but otherwise the short block appears readily rebuildable.

The cam was coated with lube or oil, and what I thought was rust wiped right off. Without the pulley installed I was not able to turn it over it the housing.

The Sprint head is a bare, hot tanked casting that has been sitting in storage for 30+ years. It needs to be completely reconditioned. There is a first option already given on it, and I should know by the end of the weekend.

I am still gathering info to match up my parts. I have a "valid" block stamping, but the casting code doesn't match any on the lists provided. So I know there is more information to be found.

Hi everyone-I need a OHC 250 1 barrel HEAD-mine is cracked-Can antone help? comix@ptd.net

Sold all my spare parts and bought a '66 Sprint LeMans...
Primatech has the heads, I know you know where to find them.

We have a perfect bare head as a core for you to rebuild, or we can rebuild it and send it to you in perfect condition - or anything in between.

I believe you know already how to reach us.
