Engine Rebuild - Inspection Results

I took the block, crank, and pistons into the machine shop yesterday morning to have them inspect and evaluate everything. No sense in buying parts and having machine work done until I know the bones are good.

I got a call back from them this morning with some good news. The cylinder bores are well within spec for +.040" and should be perfectly serviceable with a hone job. No cracks in the block. The crank journals are all to spec and will only need a polish before reassembly. After inspecting the dropped #3 piston they said it was probably usable with some light cleanup work, but I might still err on the side of caution and replace it.

Now that I know most of the major components are in good shape, I need to start planning (and saving) for the next steps.

Basic engine build will likely look something like the following:

Block

• Hone cylinder bores
• Deck block to get to a better compression ratio with the F head
• Block vatted out
• Replace freeze plugs
• Mahle +.040" pistons with new rings
• Repaint block
• New cam bearings
• New (std) main bearings
• New (std) rod bearings
• Oil pump reinforcing ring
• Chase threads for accessories
• Hone gasket surfaces

Head

• Mild port work on the exhaust ports
• Clean up mounting surfaces
• Heat vatted out
• Replace freeze plugs
• Install hardened valve seats
• Reuse valves if possible
• New manifold studs

Cam is still TBD. Would really prefer to stay running the dual SU's. May stick with a stock volvo grind and stock valve train.
