ss 350 4spd options

[mossyoak1964]

I am new to this site and have some q's about 4spd options for the 1967 ss 350. My car is all number matching with protect-o-plate. The Rear end code that matches the protect-o-plate is PL0919G
PL=4-speed close ratio 3.55:1 rear gear. I thought the close ratio Muncies where installed in z's and big blocks? This car is a L48 295hp 350 Cal. built with speed warning indicator and heater delete. Has anyone documented a m-21 in a SS-350? Thanks

PL has nothing to do with the transmission. That is the rear axle code only. What does your cowl tag show for the transmission code?

Daniel is correct. PL is only used to identify the axle type. In your case a 3.55:1, 12 bolt, Non Posi. Built Sept. 19, 1st Shift".

"I thought the close ratio Muncies where installed in z's and big blocks"?
That's correct. The M21 was for Z28's, L34's & L78's.
Can you post pics of the POP, the cowl, the Vin #, and the engine pad? If you have trouble posting pics send them to my email address & I'll try to post them for you.

BTW...welcome!

THE l48'S CAME WITH AN M-20

The Protect-O-Plate has P7R04 listed for the transmission. I will try to take some pics of the POP and post. I got the information regarding the PL being a M-21 from chevrolet by the numbers. All numbers that I have followed up with have checked out. The RPM change between gears when I drive indicates close ratio. Thanks

No idea why CBTN's has that 'close ratio' note for that axle. It's incorrect.

You car has traveled some in the past few years - CA, KY, OH, MO.

Looks like its already in the CRG data base but here you go Kevin;

Engine & Tran    Sure hope I'm wrong! Need a pic of the engine pad to make sure. Maybe it's in the data base. But the number you gave doesn't match. And of course, neither does the M21.

Thanks for posting the pics!

Your welcome Kevin.

BTW...don't put any meat into that quote of mine. I got confused with the mention of the M21 for an L48. I should have paid closer attention to what Daniel wrote! I missed your PL=...

Marty,
I sent you a pic. of the engine pad. These #'s seem to match the POP, but I realize that people have been building frauds and claiming #'s match for years. I have verified all the numbers on the car and they match the POP to Vin #. Hopefully its the real deal. Thanks

Kevin - So far everything checks out. The pad looks great, including the cowl. See if you can get me a straight on shot of your POP and I'll brake it down for you as well. A pic of the partial vin on the tran would be nice also.

BTW, gorgeous car!
