Value of a buick 455 1231738

just about to get a long block on a trade, but looking to find out how much this would cost....it is a buick 455 1231738

They cost a lot to build, depending on your goal. The water pump/timing cover on mine cost me $600... I've got a built one for sale with Edelbrock heads, cam and intake if your looking for serious power. I'm letting it go for much less than I have in it (built it for nearly 7k, selling for closer to 4k, its a steal at that, the heads alone are worth 2k!) check it out if you are interested: http://cgi.ebay.com/ebaymotors/ws/eBayISAPI.dll?ViewItem&item=160150792812
