New guy here and running into a bit of confusion with this 19.5 opposed twin I’m trying to build up over the winter. I ordered the arc racing Billet rods they offer for the Briggs opposed twins and it lists that I should be using Briggs part number 792307 pistons. Now the issue I’ve run into is that this part number is now obsolete and has nothing that supersedes it. I’m faced with a dilemma that the engine I want to build up I’m not sure what pistons I’m supposed to run now and I definetly don’t want to use used pistons for obvious reasons. Can any of you guys maybe shed some light on this topic on which piston y’all are running or would recommend using in my instance? Thanks in advance guys !
