I bought a K1 crank 4" 360 mains and chevy rods for $500 to the door last year and a set of k1 chevy h beem rods (645grams) for $226 I think. Was checking out some of the new SRP pro pistons for around $650 with rings and pin (422grams plus pin 106grams). I think that the 4" stroke is a better alternative for what I am going to use it for which is mostly street use. You can see that with balancing will be around $2000. For a couple of hundred more in gaskets, bearings and machining it is a good start on a short shortblock
