Engine bits delivered to machinist...

[Scott_Hower]

Saturday morning I delivered the block, crank, rods, flywheel and front pulley to the machinist (1500 engine). Also gave him the new pistons (County 9:1), rings, bushings and bearings (King tri-metal).

The list looks like this:
bake and shot blast the block (Sunnen engine cooker)
check line bore
check deck
bore+hone .020 over

clean and magnaflux crank
regrind 0.010 undersize main journals
index regrind .010 undersize rod journals
micropolish crank

clean and shotpeen rods
check rods for bend and twist
install and size small end bushings
resize big ends
check/file ring gaps
zero balance rods/pistons/pins; assemble

reface flywheel
dynamically balance front pulley/crank/flywheel assembly

Am I missing anything?

nitride the crank if you can, balance the crankshaft and make sure its straight, also make sure they radius the crank journals properly

Thanks; will ask about nitriding. I did ask about the journal radius as that seems to be a big reason for crank failure; I got one of those "let me do my job" look and was re-assured.

This shop does mostly custom race work; guy kind of chuckled when he saw the size of the block.

That chuckle has scared me out of some shops... they tend to treat these engines as if they were Lawn Boy mills. A LOT of respect is expected for the machinist's skills, yet scant respect is given to your four cylinder "ferrin car" engine. As if it's beneath them to do a proper job on one.

Once had to have a B block linered because the bore job was assigned to "Junior", the apprentice. After that if I dealt with an "unknown" shop, I'd explain I would bring my own mic's and bore gauges with me and check EVERYTHING upon completion and before money was exchanged. Usually the atmosphere was less friendly but at least we understood one-another.

...jus' sayin'...

Hap/ACME Speed Shop did the head.

Doc - this guy did my B engine about 10 years ago and it was perfect. He's the guy doing all of the work; it's a father/son shop and the father is mostly retired now. The tone got much more serious when I told him what I wanted and the dollar bills started adding up.

Glad to read the last post. I would be reluctant to use a shop that would not talk to me about what they are going to do.
