FS:Fresh .030 over 6.0 long block
This is a LQ4 that was hot tanked, bored .030 and fitted with Sealed Power Hypereutectic dish pistons. Crank is std. and was micro polished. The rotating assembly was then precision balanced. Heads are 862 castings with 6.0 valves installed, combustion chambers were unshrouded around the valves. Intake and exhaust ports were cleaned of flashing by hand. Cam is a stock LQ9 but can be upgraded for an additional cost. Final compression is approx. 10.4 ratio. New lower price and shipped to lower 48! $2,600 SOLD
List of new parts:
Sealed Power Hypereutetic pistons
Hastings rings
Clevite 77 main bearings
Clevite 77 rod bearings
Clevite 77 cam bearings
Mellings hi-volume oil pump (std. press. spring)
GM LS2 timing gear set
GM LS7 lifters
FelPro valve seals
FelPro head gaskets
LS6 valve springs
GM head bolts
GM crank bolt
GM complete gasket set

For several reasons if you are comparing them to forged pistons. Most of the motors on here are used for daily street driving and cast pistons (which is what the factory pistons are) will last a lot longer than forged ones. The Sealed Power ones I used are a matched set to 2 tenths of a gram and size matched to .00025". They were fitted in at .0015" to .002" and have the Duroshield on the skirts. They will never rattle, take 100-150 shots of nitrous and last 100,000+ miles. If you plan on 20lbs. of boost or a 300 shot then forged is the way to go. For a quiet, strong and long lasting street engine then pistons like these are the way to go.
I built this engine to replace the 427 in my truck because it's going in a Camaro. Now my plans are to use the LS1 out the Camaro in the truck.
