CRittaler Posted September 6, 2021 Share Posted September 6, 2021 Hi guys, I haven't been super active on my F250, still welding away, but I spotted this on FaceBook market place and had to have it 1957 Chrevrolet 4400 stake bed. It has an engine from a 66 or 67 pickup as best I can tell. 250CID inline 6 with a 4spd muncie SM420 and a 3 sped aux transmission. It was a white knuckle 97 mile drive from where I purchased it. The passenger outside dually basically disintegrated about 10 miles into the trip. 2nd gear is iffy so there was a lot of shifting from 1H to 2H to 3L when it would inevitably hop out of 2nd gear while accelerating. From what I've garnered so far, I am the 4th owner and the 1st owner to take it off the island I bought it on since the original owners brought it there.

Rembrant Posted September 6, 2021 Share Posted September 6, 2021 Cool project! I like it. There are several guys that show up at our local weekly classic car nights in old stake body medium duty trucks. They are super cool and they always sound so good going through the gears.

I'm excited for it. It was an old farm truck, sat in a barn all year and only started during hay season. Link to comment Share on other sites More sharing options...

CRittaler Posted February 13, 2022 Author Share Posted February 13, 2022 Thanks! I'm excited for it. It was an old farm truck, sat in a barn all year and only started during hay season. I did a little bit of work on the chevy when I didn't feel like working on the bullnose. The po spread some RTV in a poor attempt to seal an exhaust leak. I know I need to replace that fire starter glass fuel filter too. I pulled the intake/exhaust to have them surfaced. Everything unbolted surprisingly easy. Turns out the exhaust manifold was cracked so I ordered a replacement. While I was waiting for that to come in I did a compression test I also pulled the plugs. These were discontinued in 1980 as best I can tell Once the replacement exhaust manifold came in I took some time to port it to the remflex gasket. I managed to wrestle the manifolds back in place in January I also discovered that the carter YF carb needed bushings on the throttle shaft so I sent it to my frined in Canada that is going to bush it for me and send it back. Jumping to today, I just picked up an SM420 transmission from a 50's chevy/GMC since the one in the truck doesn't stay in 2nd. That's where I'm at now. Just sitting down to watch the superbowl and eat some snacks. Link to comment Share on other sites More sharing options...

Not sure the port matching will make much difference as those engines are lethargic, but it won't hurt either. Link to comment Share on other sites More sharing options...

The matching wasn't so much for performance but more because the replacement manifold had a lot of excess flashing in the ports from mediocre casting. You can kida see the difference between the old and new here Link to comment Share on other sites More sharing options...

Nice project I love it I dont remember what is different between a 250 and the 292 six as it have been way to many years since I messed with them. Do you know the make of the AXU. trans? I take it is low / direct / high? Dave ---- Link to comment Share on other sites More sharing options...
