Machine shop

I have an LT1 block that was overclearanced for a 396 stroker setup. I'm in the process of a rebuild and found that the previous owner had epoxied the bottom of 4 cylinders where he overclearanced for the 3.875" stroke crank and poked holes into the water jackets.

I'm looking for a reputable machine shop that does block filling and is familar with the LT1. Thanks

Other than the opti spark, the basic block configuration is just a SBC, any competent machine shop that has used block fill or is familiar with this kind of an application can fix it. The last LTx I worked on that was a similar build was some time ago. My machine shop just did a half fill with with hard block filler. In other words it was filled just to the bottom of the freeze plugs. There was no overheating issues what so ever because this was a street strip application, running deep into the 10s for 1/4 mile times.
