Are you just assembling the engine, or doing all the machine work too? Are you using cut-to-fit piston rings? Do you have to chamfer the bearing for an aftermarket crank? How many parts are being re-used and need to be cleaned and detailed before installing them? Are you doing the engine install and break-in, and do is it a flat tappet cam with dual valve springs where you break-in with singles then install the inner springs? Are you checking the valve spring pressures and install heights where you may need to cut the seats or add shims? Way too many variables / options to give a price without knowing the specifics. Stock engine usually go back together pretty easy, but strokers, and engines using aftermarket parts usually don't go together without having to rework, clearance, fit, or modify something.

IF it's -all- stock parts cleaned and ready to assemble, $500 assembly labor only. local speed shop does it with no warranty.[.] your heads ready to bolt on, your parts machined and ready to assemble. problem is , when someone does not know what to order [parts wise]to rebuild the engine and the parts are wrong , the shop is screwed. big PIA. if you order the parts and have to confirm that they will fit and work properly , add that time in as well.
