Keep 239 or swap in a 250???
Permalink  

Good day. 

I've got a 1948 Streamliner with the original straight 6 239. It doesn't run currently, but will. It will run for a bit when gas has been poured in the carb, but dies once that runs out. Makes me think its a fuel delivery issue, so not a huge deal to fix. I'm sure with some work this engine can be turned into a runner. My question is this - knowing that i want to drive this car daily throughout the summer, and take it one select road trips with the family, do I keep the 239, or swap in something a little newer with greater parts availability - like a 250? I don't currently want to go through the process of clipping the front end, etc., and would like to stay away from a V8 (everybody's done it). I can convince myself to go either way, so I'm now looking for some real world advice as to what is a better option to make this car a daily driver. 

Thanks, 

-Blake.

Blake, as sweet a motor as a 250 Chevy inliner is. Rebuild the original flat head inliner engine. I like your thinking on staying away from belly button engines. As great as a V-8 is, the inline six can deliver power and economy. Your marching to your own band, not everybody else's. My vote is to keep her original and keep that inline flat head. Cheers George.

I'm a fan of those engine, keep it. And as you've said, «...V8 everybody's done it», and how much keep those flat head? Today it's a better attracting engine than the too popular V8

They are reliable and strong.

 

Fix your fuel issue, look everywhere around it, fix everything you see that can need maintenance (distributor advance also) and it will fire every time. You can keep your 6 volts if already there, it's can be reliable too on a long run if well maintained.

 

My advise before running it on a long run, remove the pan and clean everything inside.

 

Fitz.

I,too, agree that the 239 should be respected as your workhorse. Parts are available and nice original rides are getting less and less common.

Dare to be evan more different ? How about a 60's pontiac over head cam 4.1 L (250 cu.inch) six. Now that would be cool. That would be 215 hp with the auto engine and 230 hp with the standard trans engine.
