what to watch for buying a buick 350 long block.........

If it is a '68 then it's probably high compression. The numbers will tell for sure. I believe the engine code is stamped on a pad between #1 and #3 cylinders. Buick used the same heads on high and low compression engines, adjusted the CR by dishing the pistons. Maybe the rebuilder lowered the CR for the cat piss gas we are getting these days?

to answer , half of it ... put a j- bar on the crank and it turn freely , pulled the pan , and a valve cover all good pretty clean no guk.

the blue paint was due to seller's plan to drop it into a 60's rambler ...that's blue ( sitting in the driveway minus an engine ) but it was too wide and without major surgery to it's shock towers it would not drop in.

once i research the block casting number and see that it started life as. i started my search expecting to find a rebuilt-able core . i do plan on dis-assembling it to inspect all area's .

i not expecting to drop it into the car and go..........my luck is not that good

If all the internals check out, there really is no reason to completely tear it apart. You can take the top end off and measure the bores and check them out if you want. Keep in mind the 68 and 69 350s used a different oiling system to the 70-80 blocks. Good Luck!
