Crate 383/450HP
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:

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

Re: Crate 383/450HP
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.
