Do you guys know what a shop will normally charge to bore out a block? I want to rebuild my shortblock this winter. Just wondered what machining charges ran.

 

If I remember correctly, I spent about $700 on machines charges including heads about 8 years ago. In the whole scheme of things, machine work is fairly inexpensive.

 

I just want the cylinders bored or honed or whatever is necessary

 

just had a block bored 30 over for 100 but all shops are different.

 

Weel, to do it right, I'd get the block decked and aligned honed with torque plates. I tend to overkill on EVERYTHING, so I may not be the best person to provide input....Mike

 

Guru, about as many ways to build an engine as there are uses for it....

tons of variations in the building process.....some may or may not be considered necessary for any given useage....hi perf street, is maybe one type of build up....all out racing is quite another....

sorta like choosing cams....or induction

The last one I had bored was either 12 or 14 dollars per cylinder. That was 3 years ago and I live in BFE Washington so it could be a little more or less where ever you may be.

 

Spent 'bout $900 on mine. Brought it to the shop disassembled, had them boil it, crack check it, bore and balance it,size the rods, put the pistons on and turn the crank .010. I assembled it myself. :cheers:

 

Got my block back from the shop just last week.

Bored and honed with torque plates, pistons fitted to cylinders, $195.00.

Had other work done too, so the final bill was higher. :cool:

 

I've got about $1,300 sunk just on the block prep, no head/cam/valve work. Cleaned, magnafluxed, align honed, bored, resurface block face, balance rotating assembly, check mains, press fit pistons, polish crank, resize rods etc....just about everything you could have done to a BB was done.

I think the charge to have the cylinders bored was about $125. If the block is already there, you might consider having them check for cracks and have it dipped.

 

A few weeks I spend about $350 having on my 350 having it tanked, magnifluxed, bored, CAM bearings and freeze plugs installed. They also checked to see if it needed align-bored. However I took the block to the shop bare.

 

I had my block prepped at ESI racing engines in San Diego, they are a well respected machine shop that builds many a high performance engine for local and national racers. - what I had done and their prices.....

Hot tank and Mag Block - $60

Before anything could be done to the block it had to be determined that it was a stable starting point. I inspected it at the yard and it had little apparent core shift, so I wasn’t too worried about oversized pistons, I did want to make sure there were no cracks.

-Tap oil Gallerys for pipe plugs - $50

Hardly mandatory, oil gallery plugs on a factory motor are similar to freeze plugs, they are pressed in and staked to prevent them popping out. I always have these removed and replace them with 1/4" pipe plugs. You are ensured a better seal and it allows easy cleaning of oil galleries when you get the block home.

-Machine Deck of Block Parallel to Crank CL <=.020" - $75

To get the most out of my small block I had it zero decked. This means that the deck is milled down such that the piston is very near to flush with the deck when it is at TDC – top dead center – this provides ample squish to ensure good flame propagation and resistance to detonation. This also reorients the deck to ensure it is parallel to the centerline of the crank, and perpendicular to the opposite deck, two items that not all factory block can precisely claim.

-Bore and hone w/ torque plates - $180

This is a must, any machine shop that will not bore and hone with good torque plates should be avoided, much like listening to Eminem without ear plugs. I provided my new speed pro - .040 over hypereutechtic pistons to them so they could match each piston to its corresponding

I had more things done but these seem to be the kind of things you are interested in......

 

In Nashville I spend about $150 for bore and hone with a torque plate. Expect a minimum of $1000 with any headwork.

 

I just signed up for an engine rebuilding course at a local college. All the engines used in the course belong to the students taking the course. All machining is done including boring, crankshaft turning, etc. I signed up too late to have my engine rebuilt, darn!
