Hot Rods 1957 Chevy V8- 265 or 283?

For years I have been seeing ads for 57 Chevies with 265 engines. I thought they only had 283s. So ***uming they had both as a carry over from 56, Are they same or different block casting #s? Let me know your take on all this.

 

There are '57 265 and 283 blocks with the same casting number.

 

57 265s were 2bbl only and only with a 3sp trans.....if you ordered a pg with a 2bbl you got a 283....early in the model year the 265s were painted chartruse later they switched to orange just like the 283s

 

The baseline V-8 engine, with a 3 speed transmission was the 265. Anything else with a 4 barrel carburetor, or an automatic transmission, was a 283. I have a 57 265 block and crank I bought because they also have the provision for a block mounted starter motor, although all standard transmission and Powerglide vehicles had bellhousing mounted starter motors. It was done so the optional Turboglide transmission, that had an aluminum case, could use the block mounted starter motor, even though you could not get a 265 with a Turboglide. Like has already been said, the same casting number block was used for the 57 265 and 283 engines, with only the bore being different. My block is the chartreuse color; ugly color for an engine. I'll bet there were/are a lot of guys who think their 265 is a 283. My plan is a forged bottom end, .030 over, 265 backed up by one of my built, aluminum Powerglides. It may never happen, but I have all the parts on hand for my Pseudo-Junior Stocker build. I am Butch/56sedandelivery.

 

And in 3000 series '57 trucks ...

 

265 no oil filter?!

 

I believe 57's had an oil filter

 

'56s did too - only the 55 had no block mounted filter.....the road draft tube was in a different place too

 

not true only 55 chevy had no oil filter

 

So the 283 does not have the block mounted starter provision and can be externally identified?

 

Just tore down a '57 283; it had the starter holes on the block

 

57, 265s and Turboglide engines had block mounted starters,all others mounted to the adapter ring.

 

Actually, ALL 55-62, 265/283 engines used bellhousing mount starter motors, BUT, in 57, because of the aluminum Turboglide that required a block mounted starter motor, ALL the V-8 blocks, 265 AND 283, had the PROVISION for a block mounted starter motor, whether it was used or not. So, the Turboglide equipped engines were the ONLY ones to use a block mount starter motor. The 62 327 was the first Chevrolet V-8 to use the block mount EXCLUSIVELY (also the new style 6 cylinders). 63, ALL engines used the block mount, EXCEPT for trucks where bellhousing mount starter motors were still used until "I think", 72. The 55, 265 DID NOT have a cast-in-block oil filter, but used a REMOTE and OPTIONAL oil filter; most were dealer installed at that. Again, because ALL 57 V-8 engines had the SAME casting number, the only difference in them was the finished bore size; they could become either a 265 or a 283, and ALL had the provision for a block mounted starter motor whether used or not. NO V-8's had side mounts until 1958, 283's and 348's, even though trucks still used front mounts. It's confusing!!!
