Im no expert but I know exactly what it do.... Id run the complete L67 and the 3.29 gears and keep the L26 short block for a reserve. Then keep dropping pullies and tuning until you find the limit of your parts combination then if something breaks you have the shortblock waiting. I drive an 02 gt also not modded and from what ive read people like the 3.29s better. I vouch l67 and GT trans. Besides I woundnt even think twice of top swapping when you basically have a complete drop in ready. No messing around with gaskets and reassembly just keep the L26 for a spare.What is this going in anyway??
