Looking at their add, I could get this and add a preped block for
$349.
383 STROKER SPECIAL LONG ROD
Keith black pistons, sealed power rings, M1-77 Rod and making bearing, resized connection rods, with ARP, bolts, new stoker, crankshaft, new harmonic balancer, new flexplate. ONLY $695.00
Balancing $95.00

Does a long rod help a low rpm build?
