Well, it was my intention to post this so it would go into the archives but I guess that will be for another server. I tried looking for pics so I could do it myself but no luck. So if you are curious or not sure as to what needs to be done to run a stroker crank, I thought I would shoot some pics of my experience. I wanted to save a couple bux and learn how to do it also. I think this job goes for around $80.00 if you take it to a machine shop. Ballpark.
First, get a CARBIDE BIT (around $15.00 bux)

Above there, it is mounted in an extension. I dipped it very occasionally in auto transmission fluid while cutting.
Here are some pics of the block



Know that the carbide cutter on a die grinder will cut thru the iron like a hot knife thru butter. Mock up the stroker crank on clean, lubed bearings and a rod/cap/bolts with it's clean lubed bearing on the crank. Carefully rotate and see where the bolts will hit. I did not have a piston mounted on the rod. Have a steady hand and go easy. The water jacket is right behind where you are cutting. If you do get into the water jacket, I guess you could get it welded back up before you get to the line boring. Avoid getting the shavings onto the mains journals' while rotating it. Keep 'em clean!
Just clearance out enough material to let the bolt go by(yellow). No more. I also ground the cylinder web/sleeve(blue) just a hair for additional clearance.
Anyone feel free to add to this thread about clearancing. It was my first time doing it and didn't know much about it before hand.

Looks like mine. :)

 

:thumbs: Good pics...informative too! Nicely done.

:chevy

 

very good if you dont mind i will add a couple of thoughts if you do not mind you really should have at least 1 piston on the rod for the center to keep you alligned while checking the best route should be each rod into each whole it will be assmembeled in so there is no iregularities between casting on the rods to bite you in the azz later
and last but not least have a set of main bearings in and the crank installed and torque down to specs this will keep out your shavings and give you a true base to start from :cheers:

 

Where can I buy carbide bits? I have been looking locally without success. Also, which stroker ,383 or 406? Thanks

Had to do the same to mine! Didn't take as much as you did though.








Plus clearance on the oil pan plate:


(notice the washers)
