hey im trying to find a complete lq4 for sale can anyone recommend a location.... also are the lq9 and the lq4 parts interchangable

 

Everything should interchange. Be careful swapping pistons, crank, and rods. The LQ9, and 05 up LQ4 have stronger hevier rods than the 00~04 LQ4 so crank balance could be an issue when swapping pistons, cranks, and rods around. Also the early 00 iron head LQ4's had a longer rear crank flange, so they will take a custom converter if you run one with a 4L60E.

 

thanks do you know of anyone selling one lq4 i have 317 heads well basically stock parts off a lq9 it came off a ss silverado 05 i believe will they fit wll in a 01 lq4
