Generally speaking GM uses this engine as a service replacement for 5.7's and 5.0's that were used in trucks and Suburbans and Tahoe/Yukons that will see duty as haulers and tow vehicles. That's because it is a high torque engine.

As someone who put a C30 454 in a LeMans I wholeheartedly say go for it, Torque is not a bad thing in a 4,000 car that is used as a cruiser. I wouldn't worry too much about what rear end axle ratio you have because with 440 ft/lbs on tap you will overcome any gear that installed. What could be a problem is an open rear end which will lead to premature rear tire wear on one side.

I had a 99 GMPP HO350 Vortec in my 67. 

Same HP, less torque than the 383. Pretty bulletproof. Came out of my neighbors late model stock car after many hard laps. Needed just a re-ring, new bearings and a timing chain. Ran it in my 67 for a few years.  Still running around in my Brother in laws 47 Chev and running better than ever!

They look to be extremely expensive now with our dollar, but I'd say you can't go wrong with a factory crate motor. But at the same time you could build a nice running 383 on a 350 for about 1/3 less.

Sounds like we are all on the same page.

The price is a little steep ,I agree 

Building one to mimick the crate engine might be an option too!

Just what kind of money is a GM dealer asking for this crate motor 383. The average price now to build a stock small block right is $4,000. Is a crate motor that more expensive.

 I am to assume that these prices are real American money and not our Canadian Tire money.
