The Pontiac OHC Six

Some day this will have a car wrapped around it until then it'll have it's own thread :P

So I bought a new engine stand because I did not trust the three wheeled one I own (on top of Squirrel's concerns too) and unloaded the engine into the carport after work today. The trick was to do it without having to haul the heavy engine hoist up from the basement.

Backed the trailer into the carport.

Some ratchet straps from the carport support beams ;D I wouldn't really trust the straps or beam with a 455, and the straps made me a tad nervous with this thing :-\ Lifted the engine hoist up and bolted it to the engine.

A 1969 4.1L Code. The Date code says December 1968.

What paint scheme to go with eventually?

The accessory block. Has the Distributor, Oil and Fuel Pumps.

You can see the slots where it bolts up, it's how the timing belt is tightened.

Oil's full, engine turns easily. I think I'll pull the distributor, get a drill and test the oil pressure.

Two things stand out to me that make me wonder what I'll find inside. Squirrel had pointed out that there was a paint job done over the original paint (the blue is the wrong blue too) AND the Freeze Plugs are NOT painted, which I find real interesting because it means some care was taken at some point and not a simple rattle can rebuild.

No, it was a rattle can rebuild. If it had been hot tanked the original paint would be gone. It just means that someone changed the freeze plugs after painting it.

So, when will we see how far the 292 crank is from fitting in there? at least it won't interfere with the cam or the oil pump! :)

Hmm. Anyways, it'll likely be after Thanksgiving. I have to change the pinion seal on the Skylark (yup, source of the oil) before going to CA for Thanksgiving.

What is that black tube and block near the back of the engine?

Didn't they have a 4 bbl version of this too?

looks like the oil filler.

Awesome. Another inliner. I always thought this would be a cool engine to put into...something. There was a guy with a cherry 67 Lemans Sprint with this OHC six I used see all the time at a local show. Really cool.

It looks alot like the Chevy 230/250 but if I remember correctly there are many small differences. Not sure if the intakes/exhausts interchange?

Nice work Randal!

This thread has epic potential - I've never seen one of these and I'm sure I'm not the only one that will be checking back often to see how this inline monster progresses.

Good call on the four wheel engine stand.

<< still uses a 3 wheeler... ;D

Cool engine!

I use the 3-wheeler for the V8, I was concerned about the length and height of the L6 on it.

The black tube is the oil filler neck (like an Olds on steroids :D). There was a 4bbl version, it had a high compression head too and some pretty cool cast iron dual exhaust headers. What did we determine Jim, the high output version of this engine made 215Hp and revved around 1000rpm more than the Chevy 250?

had one in a 66 tempest..
ran ok.. the lifter like noise was unnerving
you just like engines with oil pumps on the outside..
