Nearly 8 years later, I have a replacement engine, which I received today. Not much to see, but here are some pics:
I have a lot of work to do before it can be fired up in the car. So, it will be a while before that happens.
This motor is very similar to the one I destroyed. Changes are 89 mm bore, (now a 3.0 liter vs. 2.9 before), Intake valves are titanium (vs. stainless before), crankshaft this time is not lightened and knife-edged, and this engine will utilize a dry sump oiling system.
I have shelved plans for a 3.4 liter. May never get back to that.
If I had it to do over again, I'd go with something much more "standard" and pay one of the L-series specialists to do it per their recommendation. If this engine blows up, I will pay one of the well known L-series specialists to build a reliable replacement engine.
Here's hoping this one doesn't go boom.
