1949 Straight-Six engine ?s

[sweet70beast]

You definitely have a dipper motor, the easiest way to tell with out having to take the pan off is a plate that is bolted to the side of the block under where the intake/exhaust manifolds go. Your motor has this plate, post 39 picture 3 of your built thread shows the plate. When it comes to these engines it is up to you what you want to do, most people get rid of them and up grade to a full oil pressure 235. 54 and up 235's look different than the earlier 6's so they are easy to spot. In 1953 Chevy did offer a full pressure 235 in their cars that came equipped with a powerglide transmission. These engines look just like the early 6's but don't have that plate that I was talking about earlier. This is the engine that I have in my 50 pickup. These are hard to find and a lot of people want these because they look like the early 6's but they have the advantage of full pressure oiling.
I can't seem to find the website that goes into better detail but these are some good reading.
