It’s funny sometimes how we learn stuff. I had a 250ci in this1965 C10 but it had low oil pressure. I bought this 1964 inline 230 to replace it. Swapped it one weekend and started driving it. Then a minor accident took it off the road for a while.
Bought a 1963 C10 and it had a 250 in it that ran good but cylinder #6 had 90 psi compression while others had 125 psi. It ran better than my 1964 230, but I just figured it was because it had 30 more cubic inches.
Then I bought a bunch of parts from a local man. Included in the pile of parts was a used 1963 in line 230ci engine. It was a package deal. I never heard the engine run, but he said it ran fine. I figured I might rebuild it one day and put it in the 1963 C10.
One rainy weekend I put that 1963 in line 230ci on my run stand and it seemed to run very well. Engine compression was great in all cylinders. It had good oil pressure too. I did not own a cylinder leak down tool, but I decided the engine was in good enough shape to swap it out for the in-line 250ci that was in the 1963 C10.
I distinctly remember my first drive down the road with the 1963 in line 230ci. It had LOTS of power and I immediately realized that the 1964 in line 230ci in my other truck was not nearly as powerful as this one was. I didn’t know a 230 could perform better than what I had because I had never driven a C10 with a decent 230ci.
I suspect that the rings on this 1964 engine have been a problem for quite some time. Maybe since I purchased it.
