1970 Cutlass Supreme 4 speed

This summer I had the pleasure of acquiring a 1970 Cutlass Supreme with a factory 4 speed manual transmission from the original owner. I work with the son of the original owner, which is how I found out about it. The original owner ordered it in September of Ď69 and it was assembled in the 1st week of October 1969 at the Lansing, Michigan plant. He ordered a Cutlass Supreme because the insurance premiums were much cheaper than a 442 and he also liked the notchback roofline. The Sherwood green Olds was ordered with only a few options. It has the standard 4 barrel 350 (QV code) and was optioned with the M20 4 speed transmission with hurst shifter, G91 3.23:1 open rear (SE code), PO5 Super Stock 1 wheels (all 5 are date coded), D55 center console, C08 vinyl top, and U63 AM push button radio. It has manual steering and brakes. It has the protect-o-plate, owners manual and original title. I was hoping for the window sticker or sales invoice, as well, but those were commonly discarded back in the day. Being a Lansing car, there is no build sheet. Car is numbers matching, including the carb, distributor and many other components. The radiator and alternator are the main two components the are not original. Iím very pleased to have stumbled into a great car with with a great story that I could actually afford to buy!

Well, congratulations on your purchase and welcome to the forum. A wealth of knowledge in this forum. We like pictures, cowl tag picture etc. These people can answer a lot of questions. It's fun to see a legit Cutlass with a 4-speed.
Thanks for joining and posting.

I’ve started cleaning it up. I’ll slowly replace the parts store ignition and cooling system tune up parts with period correct items. I’ll be on the hunt I for a correct radiator and 37 amp alternator as well.

Very nice and unusual. The dark green looks good with the contrasting white too and interior.

That's what I thought, but the angle of the picture makes it look like the rubber hose is connected to the metal fuel line.

Great find! Once I get my V Code site updated and running again, I'd love to add your car to the 350 4 speed Supremes section.

According to the GM heritage center, Oldsmobile produced 679 M20 wide ratio 4 speed equipped Cutlass Supremes and 203 M21 close ratio 4 speed equipped Supremes for the 1970 model year. Those numbers include both hardtops and convertibles. They don’t have a breakdown of how many of each. I’m curious what the survival rate is. I would love to see some of the others that are floating around out there.

Wow, that is not many. I have owned one of each myself. I had one with a close ratio and 391's over 30 years ago. Gold with a gold vinyl top, buckets console gauges dual mirrors and sport suspension. Drove that for a year or two and sold it. It was pretty rusty and I bet it was parted out many years ago.391's sucked on the highway. That was a very quick car!

My second one I restored and made into the SX that never came from the factory. Was maroon with a black vinyl top, a/c buckets console. wide ratio. I painted it red, took off the vinyl top and changed the gears to 3;42. A good friend of mine still has it. In retrospect I wish I would have left it all original. I always liked the supreme body style better and liked 4 speeds. Of course they never made a 1970 supreme with a 4 speed and a 455, which was my dream.

Where did you get that info on production #'s ?

Pat

I emailed the GM heritage center and provided the VIN, looking for whatever info they had. They provided those production numbers for 4 speed cars.

Nice car. Your battery cable should be attached to the valve
