ZShack Built Short Block

Regular price $6,331.81 Sale

We only offer one stage for the short block.  We use this setup in house for every build from oem power levels all the way up to 1000 whp.  This will come with a full 1 year warranty for machining defects.  Unlike engines built elsewhere, we build all of our short blocks in house.  Shipping will be via truck freight, please contact us for a quote.  Core charge, we will either need your old engine shipped to us for inspection first or the core charge covered before we will send out the new shortblock.  This will be refunded once your old block has been torn down and inspected and the crank, block, and girdle are re usable.
