383 Stroker vs. 350

[BT Classics]

Hey -
Debating about an engine combo for a custom 1956 Chevy Pickup. The project is finally going back together and it is now time to figure out what to do for an engine. Althought the 468 Big Block is fun in the '72 Cheyenne, I think I am sticking with a SBC for the 1956.

Have the opportunity to purchase a 383 Stroker but the guy lost the paperwork on it. About 500 miles on motor. Supposed to be dynoed at 405HP /450ft lbs - balanced, blueprinted, 2.02/1.60 Sportsman II cast heads. Asking around $2000.
In talking with some people, they said that 383 Strokers are gas hogs compared to the 350 counterpart. Any truth?

I had a 355/350HP, 2.02/1.60 heads, built for my 1955 Chevy. Cruising I can get around 18MPG. (staying out of the 4bbl of course!) Plenty of power to light up the tires. Thinking about it now, the money spent to rebuild and work on the heads, etc., could purchase a similar HP crate motor. This has kind of elliminated my original option of rebuilding the 350 that came with the truck. (Found out it was a '72, 2 bolt main.)

This leads to my question - given the option of 383 or 350 crate engine, what is the better option? I am looking for a streetable engine that has plenty of performance but also nice for driving. 350-375HP (or thereabout).
Thoughts?
