Thread: Stroked GTX L67...

If its stroked then the distance the piston moves will be great, I don't know the b/s specs for these cars are but just figure that out then measure the stroke and compare it to stock, if the guy said it was just stroked then the bore SHOULD be the same as the stock specs, maybe a couple thousandths more if the previous owner hand the cylinder walls honed out to put the new JE pistons in. Just pull the heads off and find out, it's really not that bad. If I'm wrong with any of this bore and stroke talk please let me know.

Yeah idk the specs or yet alone anything really about what a stroker kit really does to the engine. I know the head gaskets definitely look fresh not old at all...

Stock is 3.8 x 3.4. 3.4 being stroke.
