I am swapping in a 455 and 4 speed and will have a 1970 Cutlass Convertible 350 CI 2 barrel engine and TH350 auto trans to sell. Engine and trans are currently in car and available to hear run. Engine runs well. Don't know history. I have only had it for about 100 miles. Seems original. Trans shifts well--again, do not know the history. Sold as a set. With your help will pull engine and trans in my garage and load into your truck. Located in Florence, Montana 30 minutes south of Missoula. Best offer. Pick up only--will not ship. Call or text 406-531-6939 or email david@daviddecan.com. Also available for private message on ClassicOldsmobile.com. Thx.
