Briggs and "Big Block" do not belong in the same sentence.Ive been down that rabbit hole before. My ex-stepdad growing up had a open class turbo diesel, and a super stock rail lookin “JD” with a VW engine. He got me an old “12hp” cub with the cast iron 3sp trans to pull when i was 10ish. When i got to old for the kids class i called it quits. That’s entirely to time consuming for me right now but an 82 series cub with a new EFI Briggs big block isnt out of the question in the future lol.
