The JE piston rebuild kit from SPOOL is about $2300 delivered(don't use the ROSS) Oil pump gears,tensioner,timing chain,new guides,crank sprocket about $1100 Head studs,oversized ATOMIC washers,Mains studs about $700 Block/rod/crank/possible tunnel machine work 1k minimum and basic reconditioned head @ $700 so about 1500-2k in machine work. Gaskets about $150 Unexpected pop ups $??? Engine assembly(will vary quite a bit as builders have different methods/time spent assembling motors) but expect $1500-$2500 on assembly. I have only been very basic in listing stuff just to show it adds up quite easy. If you build it do it right(this in itself is subjective though from person to person but a known good builder puts a mind at rest) as you will kick yourself afterwards for not doing so. These engines can be slapped together quite cheaply but reliability at the level of boost we speak of isn't usually held onto for very long. It all depends how picky you are and what your budget allows. Ill donate a set of rollers for you if the motor has to be used....they were what I was going to use in my current motor but a set popped up just a bit better nick again so went that way....by no means are these hammered and have very good even wear on them.
