Double spiral locks are a pain to install, but after 18, I am good at it. Use a stone to deburr rings. Wiseco uses this ring spacer for support over the pin area, common practice. I also polish each ring with green scotchbrite until it is super smooth.

These Wiseco pistons use a .078 wide top and second chrome moly ring set. This is how to check bolt streach. Short block FINALLY done.

The original Melling pump is high volume high pressure, which takes more hp to run. Generally if the engine has correct clearances, the standard volume pump will start to bypass around 2000 rpm’s. I will buy another Melling M77 pump and modify it. You can buy them with three different springs. I will set pressure at 60 psi, which is good for this 6000+ rpm engine. We have AMB tool supply in Yakima, will stop by and check my torque wrench on there gage, a free service. Back from town, my old Monkey Wards Powercraft tools torque wrench was......perfect, not even a lb. off at both 95, and 110 ft. lbs., amazing, at least 50 years old.
