    buy a shortblock, it will be cheaper. VT engines sells a GT shortblock for 3495 with forged rods or 3995 with billet rods.




    You can probably buy some rods/pistons for less and have someone work with what you have now, but it's simpler, quicker, and warrantied. There are many reputable shortblocks out there, you don't necessarily need VT's.

    yes, but to install them, you need to remove your motor, have it disassembled and inspected by a professional, hot tanked or acid dipped, the rods and pistons assembled and weighed, the motor reassembled, balanced, regasketed, and installed, at a minimum. this does not include overboring, stroking, stress relieving, coating, bearings, and a lot of other stuff which is involved in PROPERLY preparing a bottom end.

    save yourself the time and hassle and buy a warrantied forged short block, install it once, and never have problems with it again. It is worth the seemingly large price. Even if you could do all the machine work and assembly for free, a quality set of rods and pistons is going to run you 1000-1500.
