  • I was wondering if you could help me with a quick question about the piston drawing in the howell v4 plans. It says ".872 (top land only) near top of piston, and the diameter on the bottom piston is .873.
    When it says top land only, does that mean after the first ring groove from the top of piston it is .873 diameter from then on, or is all of the .300 length from the top of piston .872 diameter?
