There is a 408" small block Mopar stroker , magnum headed longblock, for $3,400 at Summit. 375hp/450#. For the driven showy car crowd. 4" stroke so you don't need much gear. 3.23 would be plenty for fun , but would not make 11's.

Cheaper than the new crank and pistons and block/Head work. Sounds like a deal.

$50 ebay all in 1 hei. $30 taylor uni fit wires. A carb, etc, and your done.
