'57 was the first year of the fuel injected 283 horse 283 and there was a dual four-barrel option for cars. But again I doubt very much any of this left the factory bolted to a 2-ton truck. Riding on one maybe...
1955 1st GMC Suburban | 1954 GMC 250 trailer puller project | 1954 GMC 250 Hydra-Matic | 1954 Chevy 3100 . 1947 Chevy COE | and more... It's true.

The Power Pak was a Passneger option, not offered on trucks. However, the Taskmaster 283 did use the same 4bbl Rochester 4G carb as the Power Pak cars did, only with a manual choke. But that's about as close as it gets, cams and heads are different. The only Power Pack reference (note the different spelling) I've ver seen inreference to trucks is the Napco conversion, which was also referred to as the Mountain Goat in the AD trucks.

I don't think mine is original then? have a hard time seeing the #on the block. | | | | | Joined: Jul 2001 Posts: 3,887 Cruising in the Passing Lane | | Cruising in the Passing Lane Joined: Jul 2001 Posts: 3,887 | cars of that era had blue 235s, no V8's were blue .... after 52 years who can say why yours is blue? would be unusual if the engine hadn't been out for major work some time - numbers are the only way to ID the year of it and if it's "original"

I've seen green, black, red and yellow smallblocks over the years. Jasper used to use a green color on theirs, lately it's been a medium gray. I do know that GM used a nasty greenish yellow on the '57 Passenger use 265s.
Bill Burmeister | | | | | Joined: Oct 2008 Posts: 20 New Guy | | New Guy Joined: Oct 2008 Posts: 20 | Whats the price of a good running 283? thanks | | | | | Joined: Mar 2004 Posts: 6,214 'Bolter | | 'Bolter Joined: Mar 2004 Posts: 6,214 | Puryear, The easyest way to tell if you have a 1957 283 is to look for the "side" motor mount bolt bosses (the 3 raised nubs on both sides of the block that the motor mount bolts to). 1957 is the only year 283 that does not have them, they still used the front mount. ALL SBC's from 1958 and up have side mounts. As for value, if it's a true truck motor it's worth about what any running SBC is worth. If by some chance it's a car engine the value could go up. The stamped number on the passenger side tab in front of the head will tell the tail.

I think he is looking for an actual number. I would say a complete 283 that needs rebuild a good price would be $300. No more. I know a guy not far from me that has one for sale.... he is asking $300 but hasn't sold it in the past 6 months although I will admit he is not advertising it....just word of mouth. | | | | | Joined: Apr 2005 Posts: 1,971 'Bolter | | 'Bolter Joined: Apr 2005 Posts: 1,971 | That could be a hard question to answer. 283's are still all over the place and rebuildables can be had for $10 to $600. A running 283 could be from $10 to $1500. I've spent $600 for a numbers correct block before. Power pack head are out there and you will spend more on them than they are worth unless numbers matching is your game. How specific do you want to be with correctness when you place it in your truck? If numbers are not important, I would find a 350 (cheaper and easier to find and rebuild) and dress it up to look like it belongs there. Here is a couple of blocks. http://losangeles.craigslist.org/lac/pts/1503740963.htmlhttp://inlandempire.craigslist.org/pts/1498230929.htmlhttp://joplin.craigslist.org/pts/1492962928.html | | | | | Joined: Oct 2008 Posts: 20 New Guy | | New Guy Joined: Oct 2008 Posts: 20 | Ok I checked the side of the block and it does have the 3 holes so not original. I got a free 283 recently from a friend and he said the motor had been rebuilt. But it did have some rust in the cylinders but I manage to get it out(sat out side for ruffly 15 years but it was all sealed). so hopefully I will have it running this winter. Its time to replace my worn out 283 with something a little fresher.

There are camel hump heads out there with 1.94 valves. It's a case of using the same casting for a different application.
