bell housing bolt painted or black phos.

[john302]

Here is a good question. The bell housing bolts are plated black then bolted to the block and painted orange with the block and bell housing.Is the bell housing bolt that is used to hold the starter wire harness clip painted or left black phos????Maybe the corvette guys would know? JohnZ? Looked at a few original cars but hard to see. My last two restorations I painted them. What does NCRS think is correct? Carlisle judging? thanks John Allouez Restorations     p.s. I am restoring that special car and these small details are important to me.

That bolt got painted at the engine plant, and the car assembly plant removed and re-installed it to attach the harness clip; if you're really anal, it should also show socket marks, with the paint broken between the bolt head and the clip.

Thanks for the info John.I thought orange would be correct because the bellhousing bolts match. If the bolt was installed later the head marking would be different.  thanks John  p.s. The paint will be chipped off.

JOHNZ, have you got a good pic of your bellhousing overspray. was there alot of orange on the bellhousing or was there a template placed over it?

There was no mask or template used - the bellhousing essentially got heavy overspray from painting the rear of the block and heads, and the coverage on the bellhousing varied greatly depending on the sprayer. The clutch fork usually shows some orange overspray as well - it was installed at the engine plant (but the rubber boot was installed at the car assembly plant, and has no paint on it).

John,did that also include the 67 z/28 motors? The bellhouseing got overspray? I am at that point now and was wondering about how much overspray if any.Would you say about 1 or 2 inches?

Yes, the process was the same for all engines; 3-4 inches of coverage was typical, but it did vary widely - there was no masking.

Thanks John.

As JohnZ pointed out, I installed my clutch fork without the boot to allow some overspray on the forward face of the clutch fork.  The inspection cover was also installed and received some overspray...correct?

I may have got a bit heavy with the overspray on my bell housing but tried to copy the approximate overspray pattern that I have seen on other bell housings I have noticed at swap meets.

The inspection cover is orange also and the bolts.There are a few different design inspect covers.The nos ones are incorrect in many ways.   John  Allouez Restorations

I'm confused [easily done these days! ] I thought engines arrived from Flint/Tonawanda as already painted long motors, as per pic in assembly process report?
Or this this thread specific to z28?

X2  What he said and if they were painted that means they were stamped as per other thread.

Funny you should mention the stamping thread, it was my reading of that one which got me wondering exactly what happened when, which has led me back to this thread!   

However, regarding the stamping thread, perhaps John was meaning that the engine code was stamped long before painting, perhaps before assembly of the block even began.
After the long motor was assembled, the pad was masked and the motor painted - off it goes to Chevrolet.
The partial vin was then stamped at the start of the Chevrolet engine dress line to an already painted engine, with no paint on the pad.

But I surmise, we need John to guide us to the light. 

[tmodel66]

That makes sense. It was the only way to keep the engines IDed cause all the engines would look alike.

[My68SS]

For sure, though the engines were segregated into bays according to type [engine code], making it easy for the hoist operator to get the right engine as specified on the broadcast sheet.
