64 GTO PHS Baltimore Plant
This appears to have been a 78X 3spd 4bbl
Is "RB" the correct trans code for 3spd ?

Seem to remember Baltimore coding is all wacky ,,, I think.
This car is only physically presenting
Power Steering and Power Brakes
Console , Back-Up Lights , Manual driver side mirror
and some 65 style standard seatbelts

Is there anything missing or added compared to PHS ?

It has a complete 78XW engine about 100,000 units too early
And a 4spd

Nice solid looking convertible
Skyline Blue , Blue Interior , White Top

Shame there’s a Chevy air cleaner lid on it instead of the lovely original chrome unit with the short snorkel.

b-man refresh my memory if you can .
Where is the casting date on 64 - 4bbl intake - - rear - or bottom
And casting dates on 64 - 9770716 heads - - underneath covers - or below the exterior rail
In case the seller wants to get down to brass tacks

Those air cleaners have always been few and far between.
Once in a while I would luck up on a 326 HO car with a painted 4bbl version of it.
The top piece was the same on all the 326 2bbl - but painted

Intake date codes are on the bottom of the intake and head date codes are under the valve covers.

Thanks Bart
I doubt the seller will want to get that deep.
But he could still check the block date on a clean engine pretty easy.

What's the EUN are you using?

I have it at about perfect for it.



I also can't find my notes on the tranny code, but should be in the GTO 'Bible'? (that is buried at the moment)

[Baron Von Zeppelin]

The EUN for the original 78X on the PHS / PoP imprint should be perfect.
326254. ( 06B body date)

The EUN for the current 78XW that is installed is about 100,000 units earlier than that.
225103

Just found an old 2009 post from John V that "RB" is for 4spd Wide Ratio

Still hunting info
Maybe the X on that particular PoP from Baltimore was generic
And it should be a 4spd 78XW engine code.
