lq4 tolerances
lq4 tolerances Did a quick search and came up with nothing. Im looking for the longblock clearances and specs for the crank thrust, main cap bearing, rod bearing, camshaft thrust.....etc.. Anyone have this? My machine shop didnt have it. Im about to assembke this motor and want everything checked.

Just a hunch but I'm pretty sure they are the same as the ls1 which should be easier to find info on. The lq9 I'm assuming would be different because of the heavier duty rods but it might be the same as well.
Clearances from an iron block to an aluminum block will be different because of expansion rates. From the factory, probably not by much, but when building a good higher power engine, it should be set differently.

Did not know this but it makes perfect sense. Thanks for the correction.
