I couldn't give away the vin 9 307 out of my 86. 442. I eventually sold the dual snorkel, carb, and cam/lifters seperately....then scrapped the rest. Sold the transmission for ~$300. So around $550 total.

Regarding the ls swap....I wouldn't let anyone discourage you from proceeding as planned. I swapped a 4.8 and 4l60e in my 442 around 4-5 years ago.....best thing I could have done from a driveability standpoint.
87 Nation, thanks for your response and some pricing, most important thanks for your words of encouragement. I new when I got on this site people would have their opinions on the swap, I'm OK with that and value everyone's opinion. And yes the drivability now is better than what it was, and having the convenience to turn the key and go anywhere and not worry about vapor lock, carb issues, flooding, bogging down is a nice feeling. .

The 200-4R has value. They are getting rare and are not difficult to build for 400-450hp. They are the real deal for a non-computerized OD trans option, and a much better gear ratio than a 700-4R. If it is truly an OZ trans, then that alone is worth $500 around me. 10 years ago they were $100-150.
Thanks 64nailhead, Just confirm it is not an OZ trans tag. next is confirming the engine. Thanks for the information.

That's out of an 87 full size car, B or D body with a 307 and 2.73 gears.
Thanks ELCAM, I appreciate the help. I now know what I have, next I will verify the engine.

Ill concure with what the others are saying. The value on the trans is somewhere 350 to 550. Value on a good 307 is junk to the typical bonehead, yet, for a builder of old vintage iron..., 250 to 350. The Olds 307 gets into the area of the Chevy 305, and too many "mechanics" today are not. Somewhere, we changed a craftsman into a parts replacer, JMHO.

I am slightly partial to Oldsmobile, but also related by family. The 307 is a good reliable V8 as long as kept within its limits. I have several even though no projects current, I don't toss. One nice aspect of the 307 is interchangeability across the line. Therefore, if you have a Olds 350 with a rod knock, the crank of the 307 will work just fine. This goes the same for a lot of the other parts.

Tucson area: engine 250-ish, trans 350-ish...

Your trans is from an 87 full size
87 kc is on the tag.
Please reference this chart.

THM 200-4R Application Chart

This chart shows all the information I could find on the various 200-4R calibrations.

Hopefully it will help those looking for good used transmissions/cores or B/D/G-Body owners that had their 200-4R replaced with a wrecking yard unit & fall under the "All 200-4R's are the same Joe, it'll fit" syndrome {my 85 Monte Carlo SS had a code "3OG" trans when I bought it}.

DECIPHERING THE CHART CODES:​

The transmission application tag is located on the passenger side rear of the transmission on the case just above & forward of the trans mount.

1982-1985 transmissions use a two letter code on the tag & 1986-1990 transmissions use a three letter code with an "F" at the end of the code {there may be other letters but all the 86-90 transmissions I've checked have an "F"}.

1982-85 transmissions use a 13 digit numbering system to show what it is & when it was built. These numbers are on the bottom of the transmission tag below the letter code {EXAMPLE: 123 2T85CQ1234}. The first three digits are the Julian date {the date the transmission was built, julian date is the start of trans production so 001 would not be january 1st. The 4th digit is the Plant Shift the transmission was built {1=1st shift; 2=2nd shift; 3=3rd shift}. The 5th digit may be a letter or number & is the code for the Hydramatic plant that the trans was built at. The 6th & 7th digits are the model year of the vehicle the trans was originally installed in. The 8th and 9th digits are the two letter code of the transmission & denotes internal parts & valve body calibration of the unit. The 10th through 13th digits is the serial number of the unit.

1986-1990 transmissions use a 15 digit numbering system {EXAMPLE: 9 123 2T86CZF 1234}. The 1st digit is the Calender year the unit was built. The 2nd,3rd, & 4th digits are the Julian Date {see above}. The 5th digit is the Plant Shift the trans was built. The 6th digit is the Hydramatic plant the trans was built at. The 7th & 8th digits are the model year of the vehicle the trans was installed in. The 9th & 10th digits are the two letter code of the transmission & denotes internal parts & valve body calibration of the unit. The 11th digit is the letter "F". This denotes that the trans is a 200-4R {GM decided to add a third letter to the code that will show what transmission family it is, 200C = "B", 200-4R = "F", 700-R4 = "M", etc...}. The last 4 numbers are the serial number of the unit.

Yeah, I have that exact trans, not a H/O trans.

The 200 in any form at their current age needs a rebuild. The later 442, MC SS and GN/GNX units had a couple steps up on the rest of them, but for the price of the servo, valve body , one other part that is slipping my mind at the moment, the price to rebuild and upgrade those parts is minimal to say the least. They are worth money as the cores become fewer. And the upgraded parts aren't as popular as they once were, but all of those parts can be found at reasonable prices.

Good luck with the 307 though.
