is this worth buying

71 block with 460 crank , football rods with arp bolts, 429 scj pistons milled and fly cut , c8 heads with ss cj size valves its a short block with the heads fresh build $1000

If the block and/or the heads are not cracked and the machine work is done properly and it has not been run to death, I think it would be a good deal. If it does have problems you could part it out and not take a total loss.

Are the heads off?

yes head are off

its fresh built out of m shop

So has the block been bored? They do make .030" SCJ pistons. If not I would check the clearance on the pistons to the block. Are the heads ported? Do they have hardened exhaust seats? You did not give alot of information. Has the crank been balanced for forged pistons? 2Y or 3Y crank? Cam, timing chain, pushrods, guidplates, lifters, new/used/brand? Does it come with an intake? Lots of things to check and consider on a used/rebuilt engine.

Are you going to try to run this on pump gas? The compression could be up to 12/1 with C8's and zero deck. Nitrous would not be good either with the raised ring lands. If you want to run pump gas you could swap the C8's for D3's and be good to go. So your intended use is also part of the "if it's a good deal"?

its going in to my mud truck , not pump gas I do have set of d3s but the c8s are ported and have arp studs and guide plates comes with
a custom grind cam he said its about 550 lift but he didn't remember the rest of the specs but its in and degreed has comp cam double valve springs and Chromemoly pushrods the bore is stock has moly rings

If you figure 3-400 dollars for the heads, and 3-400 for the cam lifters timing chain pushrods rings and rod bolts and bearings ect., it does not sound like do bad of the deal. The standard bore with SCJ pistons and moly rings would bother me. If I knew it was a low mileage block with round cylinders, and the pistons are clearanced properly, I would give it a shot. If you have to bore it .030" with new forged pistons and rings, and rebalance it, that will cost a chunk of change. Did a customer just not pick it up, and the machine shop just wants it gone?

It's not hard to run up a $1000 bill at a machine shop. As long as you don't plan to bottle feed it. I'd buy it and run the snot out of it. It looks like pretty good hp. per dollar to me.

No Doubt. If the heads are done up nice, you would likely drop at least 7-800 dollars to have them built yourself. I used the 3-400 dollar example, as I have seen alot of used ones sell around that price.

well I picked it up, it all checked out i'll see what runs like when I get it done

For just a thousand dollars that is an outstanding deal for everything you're getting and from a horsepower-to-dollars ratio.
