Forgot everyone doesn't have a L98. But I was almost right when I said it could be a crack in the block and it turned out to be a hole in the block..Since the machinest put the hole in the block, then tried to cover it up with JB Weld wouldn't he be liable for the damage and have to give you a new block? Seems to me you have him dead to rights on this one.......WW

Assuming the guy with the grinder notched the block somewhat evenly, what assurances do you have that one of the other ground spots will not crack later? It is likely quite thin.
There is a solution for your block, but welding up 1 hole is not it.

I appreciate the kind words. He may not need a block though. I have solved that problem (hole in the pan rail) reliably, and somewhat inexpensively.

I'll bet this isn't the first time that someone has struck water while clearancing an engine. I'll also bet that this won't be the last time that someone will use an inch or so of Hardblok or Moroso block filler to fix that problem. The block will have to be re-honed but the problem will go away. No more water leakage.

Finalist 2020 C4 of the Year - Modified
Silver solder is a good choice. It is a tad pricy but it will hold up. I had an engine blow a head gasket between two cylinders once while drag racing. When I tore it down I had about an 1/8 inch of material gone off both the head and the block. An old welder I knew fixed the gaps with silver solder and I was back racing the next weekend with the same engine.

TPI Jim 421.
I forget Jim's last name.
He lives in Utah.
A longtime mechanic like myself.
Jim has completed numerous longblock engine builds for other members here on C4.
He seems to specialize in street - strip performance engines.
Very likely can do a full tilt road race engine build for You.
Road race engines are some of toughest to build.
They have to last hours at a time of wide band power ranges,
encounter high G forces that play havoc with wet sump oiling systems.
Accusump is a band aid temporary fix to me.
I know you feel different about that.
If you put $30 K into an engine for road racing ?>>>>
What is another $2 to 3K thousand to spend on a Dry sump Gilmore belt driven oiling system, lines & fittings, Oil & Air-artion separator holding tank with a nice Earl's Oil cooler ?
They dry sump piston powered airplanes for a very good reason too>>>
Wet sump impossible to work with under such operating conditions also.
Airplanes keep on flying with the dry sump oil system.
No Main & rod bearings lost in the engine spinning the propeller.

Are you planning on a complete new engine build ?
Or using your current short block & heads ?
All the problems you have had with this motor,
most would be scared to touch it.
Motown iron block a good choice for the money spent.

TPI421Vette built my 396. I think someone mentioned balancing as a key to long life. Jim had mine balanced to 1/2 gram. This is one smooth running engine that should run for a long time. But Jim can't control how I drive it or tune it or maintain it. In other words, how could he warranty what I will do to it. He can't. But I would recommend him to anyone.

what the heck its a good block just has a few holes in it. good rotating assmbly save for a few busted up pistons and what else do you need for a good road race motor ask most engine builders and they woulnt tell you they have no idea!!!!!!!!
