Attn. 265 Racers.What block is the best?

In 1959 there were some replacement 265 motors built for trucks. They were truly 283 blocks not bored all the way, reat thick walls and a neoprene rear seal. We found one. Good luck!

That is what I used in my old '56 Chevy. Had side mount bolt bosses. I got protested once over that. Some tech guys that did not know me & the car would feel for side mount bolt bosses. Then question me about it. At an out of div race, was protested. Told me "I know that is a 283" block! I had just learned about thick cylinder walls from Jere Stahl. That gentleman taught me a lot. Even located a guy locally Sonic Testing. Sure enough, the cylinder walls tested close to a tenth of an inch thicker than a '56 265" block I had in my garage. The deck was very thick as well.

I would love to have a picture of one of those blocks.I had a Corvette guy( He claims to have thousands of sbc blocks) in Detroit tell me that there was" never a 265 block made with side mounts".He wants thousands for some of the 265 blocks he has,and they are not even dated for an early Vette.

That was about 50 years ago. I didn't take pictures of everything like many do now. Would have to screwed with having them developed too. LOL

I have a 57 block that ends with the letter C that has been magged and cleaned, Also have a brand new small journal 3 inch stroke crank.

57 blocks had no side motor mounts.

Side mounts did not show up until 1958.
