I have one under assembly, assuming I don[t die from Covid first. I just spent a week in ICU with blood clots in my lungs. It uses a modified stroke 235 crankshaft and pistons, H beam rods for a Nissan 2.4 liter, a 250 oil pump, and several other major modifications. I've been doing major engine mods for over 60 years.
