......... Had billet caps installed on block - suppose to be .002 cut on block but a stock t-chain fits it really tight. Wondering if shop really bored and honed caps to block....TIA
There is no fixed amount of material that is removed in a line bore so that dimension not going to give you any usable data?
Installing steel caps require a line bore because the steel caps are made oversize as the "register" in the block, and other dimensions, that hold the cap can vary.
Once the caps are fitted and finish installed with a line bore, an align hone is done to set final clearances and to have all bearing saddles in close to perfect alignment.
We never do ANY engine build without an align hone if steel caps are done or not. This is necessary as the factory tolerances are not held as close as ours, and block flex and working over time and use will change these very close tolerances. We want the crank and block bore to be as good as we can possibly get it for proper oil clearance and bearing life.
It is too late for you to worry about your machine shop doing the job properly. In very few miles you will see bearing material in your oil filter if it is not right.
This is why you should get familiar with the machine shop and person doing the work
before you hand over $$$$, not be guessing at this point to wonder if he did it correctly?
