My truck originally had a 235 six cylinder. The block was cracked from one end to the other when I bought it. Someone left water in the block over the winter. I replaced it 7 years ago with a 261 6 bolted to the original 3 speed and original rear end. I drove it like that for a few years but now I have decided to step up to a V-8 and automatic. I purchased a never rebuilt 327 out of a '65 canadian Pontiac Pariesienne with about 150 Thousand miles on it. ( Canadian Pontiacs where built on a Chevy frame with Chevy drivetrain ) I am planning on rebuilding it but I was wondering if anyone can tell me any more about the original specs on the engine. What kind of horsepower did these put out stock? Casting Number: 3858180 Date Stamp: G17 64 Front Pad Stamping: 85 5620570 Heads: 3782461 Behind the timing cover: 810 - 180 and B T. G7 My plans are to do a basically stock rebuilt then dress the engine to look like it came out of a 64 Vette, Finned Corvette Valve Covers and 64 Corvette Air Cleaner.
Sounds like a good, half way worn out. You could get another 100k miles out of it no problem. SBC If you take it to a shop, make sure you get the same block/heads/crank back!!! They'll play dumb & ask you for the numbers, so take notes, take pix
Depends on its current condition, I have seen 'em with well over 250K and some with 75K both worn slap out. 59Chev, Here is something for you to read. Just for chits'n'giggles. http://enginefacts.com/chevrolet327.php
