I like the 60-1 or 62-1 for the street, makes 400-500 Hp even more if you want, but works great on the street great spool up.
If you want a real simple set up with out much fab work I would do a blow through. Get a exhaust manifold from Tom Lowe, a 4 barrel manifold and a 650 Holley carb, good fuel system, and a 60-1 turbo with a "P" or "Q" trim turbine and bolt it to a stock 250/292 with forged pistons.
All you need to fab is a 2 1/2" pipe from the turbo to a carb hat
and a exhaust pipe. And you are ready to go.
