I have a 39 Chevrolet Master Deluxe. The orginal 216 engine is bad. I have a 230 and 235 engine witch one is a better motor. My plans are just going to car show and drive on the weekends. The transmission has to be a automatic transmission. Which transmission would work with 230? The 235 was made in 58 not sure about the 230. Just looking to rebuild the engine and just make it a good cruising car. Thanks

Either are good engines, but the 230 will allow you more transmission choices, and will accept a TH350 transmission, which is a better choice for an automatic. An even better choice would be the 250 Chevy six if you can locate one.

I have looked for a Chevy 250 for a year and cannot find one.

Not sure where you're located, but I did a Craigslist search here a few minutes ago, and a Chevy 250 six popped right up for $500. Says it was rebuilt not long before it was pulled and has shop receipts with it.

Man that seems like one heck of a deal. I have a 57 with a 235 that I have wondered about using a 250.
How about a quick mini lesson from someone/anyone on problems of switching one? Thanks. Mel

You'll need a motor mount kit to side mount the engine. Also need a crossmember to support the trans if you are changing transmissions too. Need bellhousing mount adapter brackets for a newer bellhousing to bolt to the stock mounting points on the frame. Not sure on driveline length, but I believe it will be the same length.
If I was doing a swap from the old 235 to the newer 250, I'd also want to swap in either a TH350, 700R4, or a T5 five speed trans if you want to go to a stick.

Thank you, fast and detailed. I would likely lose the three on a tree and go with a 250 auto. Thanks again. Mel

A 250 with a TH350 would really make a nice 6 cyl. swap in your car.
I bought my wife a 1970 Nova years ago with a 250 and Powerglide. It was OK, but not a great setup. The PG started slipping, and I swapped in a TH350, which was a boltin for her later car. What a huge difference in driving with the 3 speed automatic over the 2 speed.
We drove that Nova loaded with two adults and two kids, plus all our suitcases from Oregon to Colorado and it had no trouble going over the Rockies at over 11,000 ft. at Berthoud Pass.

You do realize that swapping in a 230/250 will end up being a complete drive line swap including the rear as there aren't any modern transmissions that mate up to your torque tube rear. The easiest swap would be the early 235/261 with the water pump in the correct location...that's as close to a direct bolt-in as you can get.

Yes, I do indeed understand it's a complete drivetrain swap. But I would personally rather upgrade the entire drivetrain and have a more modern drivetrain. Once you decide to not keep the car 100% stock, might as well make it easier to get parts for. And since he's already stated he'll likely lose the 3 on the tree and go with an automatic, he's up for a complete drivetrain swap I'd guess?
Heck, I'd even consider changing to a 700R4 trans to get OD and make the car road worthy for longer trips.
