 Welcome to CHP!

 17059213 is from a 1979 Chevrolet/GMC Truck 350cid or 400cid, w/ Manual Transmission.

 2638 is the date code, which is the 263rd day of 1978.

Cool that's what I thought just wanted an expert opinion, would this be a good starting point for a mild olds 455?

 Let see what Cliff says. He would know more about it. I just "decode" or "breakdown" this stuff. Take care!

Cool thanks Ethan thanks for the speedy response

   I believe that carb would work fine on your 455. It is the Large bore and has the adjustable apt. good float design. Probably a single main air bleed design. Probably set up pretty lean, usually the chevy truck carbs were set up that way. The air bleeds may need to be modified (made smaller) not hard if you go slow and have patience. Only other small problem would be the chevy type of fuel inlet which goes to the side instead of out the front like the oldsmobile did originally. then, you should convert it to electric choke to make things easier. Throttle linkage may need slight modifications also. Should work fine though. Make sure it is in good enough shape to rebuild. too much warping can be "unfixable"

thanks for the reply, over the weekend i found a 17058253,it came off an olds and i got the throttle brackets and all!I just called cliff and he is going to send me the stuff to rebuild and get it calibrated right, i guess i better start re reading his book again

The Chevy truck unit is excellent, first of the later style single main airbleed units.  I'd still use the Old's carb, front inlet, Old's linkage, and it's equal to the Chevy from a performance standpoint......Cliff
