Hi,

I am looking to put a 383 into an 84 T/A and came across a pretty good deal. Just wanted to see what you thought about these specs - the engine is selling for $1500 cheaper than Jegs zz383:

This engine would be EXCELLENT for a Street/Strip car, Street Rod, or Pickup Truck. With 450HP @ 5500rpm and 460ft lbs of torque @ 4500rpm this engine has a rough idle and will run on leaded or unleaded 91 Octane pump fuel.
The balanced rotating assembly (typically includes crankshaft, pistons, rings, connecting rods, rod bearings, balancer, and flexplate) featured in this engine:

• 3.750" stroke crank
• 5.7" forged big beam rods with ARP rod bolts
• 10 to 1 compression hypereutectic flat top pistons

More special features of this engine include:

• Seasoned 4-bolt main block with one piece rear main seal to prevent oil leaks
• Block has provision for mechanical fuel pump
• Engine comes with flexplate
• Deck head gasket surface on block to ensure a good seal
• New Hydraulic flat tappet cam with .512" valve lift
• New Dart/World heart-shaped chamber, 200cc intake runners, cast iron, straight plug heads with 2.02"Int/1.600"Exh swirl polished stainless valves with undercut stems for even more flow

• New Revolutionary 1-pc design molded rubber oil pan gasket with load limiters to prevent over-tightening and higher temperature resistance than standard cork-rubber gaskets
• New Brass expansion plugs
• New Edelbrock Victor Jr aluminum intake manifold
• All parts are painted separately before assembly for that show quality look

This engine comes completely assembled with oil pan, driver side chrome dipstick and tube, timing cover, harmonic balancer, valve covers, and an Edelbrock Victor Jr aluminum intake manifold.

 

Sounds like an eBay special - all the right words, the parts you actually get are a different matter.

Proceed only with extreme caution.

 

You hit the nail right on the head...it is an Ebay engine. The only reason I am contemplating it is because the guy has 100% feedback with 500 transactions.

I think will just go the safe route and buy it new from GM.

Thanks for your input.

 

That's a decent feedback rating. If they were scammers, it would be reflected in their rating.

But, GM is pretty safe.
