What's the going rate on 350 4 bolts (1st gen) nowadays? I have 2 or 3 extra's pretty much complete minus accessories that were running /driving when I pulled them. Would still consider them to need rebuild/ refreshing

Richard,
It all depends on whether it is a virgin block that has not previously been rebuilt and if it can be rebuilt i.e. no cracks, lifter bores good, with or without heads, exhaust manifolds etc. Believe it of not, there are not a lot of 4 bolt 350 2 piece rear seal blocks that are any good around my neck of the woods anymore. A lot were gobbled up by the stock car racers over the years and a lot of them are approaching 40 - 50 years in age. In any event, I paid $200 for a short block. Obviously I then had to put money into it for magnifluxing and a machine shop determination that it was good to build it .030 over, new pistons, new scat crank, reconditioned stock rods, cam, rigs, bearings timing set, lifters, other heads I had redone with hardened exhaust seats, valves,knurling if needed etc. etc. If your engines have all the stuff that 67-72 Chevy truck restorers are going to need such as exhaust manifolds, pan, heads, intake, pulleys, PS brackets, alt. brackets etc., then I would think $500 would be fair, if it hasn't been previously bored. Might want to pull a head and measure the bore so that a prospective purchaser would be pretty certain, at least from a bore stand point, that it is useable.

Thanks for the reply Rick. I just got realizing how many i have sitting here that i don't need. lol They were all pulled from this era trucks other than one that i am not sure about. It came with a 72 Blazer that I parted and was already out of the truck. I may pull that one up and go thru it to get all the numbers and info I can get and go ahead posting it.
