Just curious.
About how much would one expect to pay to have a new BBC block decked, cylinders bored and honed, soft plugs, bearings, you name it. Pistons fitted. The whole enchilada that a machine shop would do with new parts.
Just looking for some additional education.
Thanks.
Your gonna see numbers all over the place. Obviously an expert experienced machinist who is geared mainly towards performance engine building is going to cost more than a general shop that builds industrial parts.

I just needed something to get my expectations in line.

X2, and really spend some time researching if you don't know them, cause there are a lot of people out there that will screw you over way too quick.

Agree. Great advice.
That's not the issue here. No problem there... just doing a little research on what the ranges are out there these days. Even if a trusted friend is doing the work.... I want to know what is fair. Just researching. I don't want to take advantage, as I also do want to get gouged. Just checking.
Thanks for the responses. Totally understand the broad range thing.

Fund,
Those figures I gave are what I paid a few years ago and the work was done by a machine shop who does a majority of machine work for some very well known marine builders in NJ. This same Machine shop has been doing my machine work for the past 10+ years. :)
Prices may have gone up since then but they should give you a ballpark.

It was just the ticket. I just wanted to get my expectations in line with what's going on out there. Ballpark was perfect.
Thanks.

It depends on what you're looking for. If you want to do the basic machine work and slop it together, add a couple hundred in assembly. If you want a full blueprint assembly, that's going to entail those parts being dry-assembled at least several times.

I agree with Chris, this will add significantly to the cost and it takes a long time! Last engines I helped match weights within 1/2 gram for each piston and then smoothed all sharp edges, it took a LONG time! Gotta add in a bunch of other stuff such as filling ring gaps, crankshaft end-play etc. I group that all under assembly and that's where your engine builder really shines!
For instance; When I ask my machine shop (Rogers Speed Shop) they will give me matched bearings for my application when cutting or polishing a crank but we still have to measure clearances and mock it up.
