Buying a SBC400 pls help!

Guys,

i've been offered a SBC 400, with the following data:

Casting: GM330817

Date code + ?? : D23 76 T5 LH6 (what are those last numbers????)

Suffix on pad: 10427 CSX

Intake: 348248

what exactly is this?
Is it worth looking further into, or should I walk away?
Guys wants $1,200 complete with waterpump, carb, manifolds, HEI ignition, wires and stand....
Engine has 72.000 miles on the clock, nice used paint -not recently painted.
Been out of the car for 10 mths.

So far i've been it seems that I'm looking at a 400 out of an '76 El Camino, with production code LT4, and 175 HP.....

Any help appreciated...

Thanks a lot

its a 74-76 400.
$1200.00 ? damn. Are you planning to drop it in & drive it ? or rebuild it ?
Either way,I sure the heck dont see 1200.00 for it. If I was looking for a rebuildable 400 I wouldnt pay more than 200.00 maybe 400.00 if it was in great shape. If I was planning to use it as it is, I dont know, surely no more than 800.00 or so.

I agree with stepside, no way is it worth $1200
Since it`s complete top I would offer would be about $450 and that would be generous, while it`s true 400`s are scarce, there not that scarce.

Since I am in Europe, American stuff are more expensive over here.

But with the things you guys mention, I can probably buy one in the US and have it shipped cheaper than buying this one.

The engine does (according to the seller) not need a rebuild.... no selling engine does.....

I'll reconsider this offer, and see if the price is negotiable....

The heads seems to be the originals by looking at the markings on the front (882's), and the carb is a nice looking Q-jet.

74000 miles on a stock 400SBC is 75% service life before you start having water problems. May or may not need to re bore, but definitely would want to tear down, boil out block and heads, and re assemble. If I were doing it, I would go ahead and have the block bored, new pistons/rings, bearings, oil pump, cam and bearings and a valve job. Having said all this, I would look into having Sumit Racing or Scoggins-Dickey ship me a new crate motor and compare the two costs. The $1200 initial cost is just way to much for all you will have to spend just to make the motor dependable. By the way, the last small block 400 I purchased was supposedly a running motor and I paid $150 for it less a carb. Tore it down and it did not even have a ring groove. The block, a 2 bolt main, became a 406 IMSA race motor (splayed 4 bolt) and I have all the other parts to build a 383 when the spirit moves me.

According to what I gathered outta an old issue of SuperStock and drag ilustrated.A 400 block w/ a block # ending in 817 is a good block(kinna like an 010 350 block).They do go on to say that if your looking for a 4 bolt block though,then 511 is the # to look for and to avoid the non-511 blocks as far as 4bolts.
Anyway good block or not.$1200 for a stock 400 w/ 72K is crazy.I'd say its worth $400 give or take.
