Big Block Briggs Model 61 (35-40 hp) .020 Over Dish Rod & Piston Kit (pt num 8082)

Briggs Big Block 35-40hp .020 over size (3.385 Bore) rod and piston kit. This kit was developed to replace the discontinued .020 over stock cast Briggs pistons with a high quality billet piston. We have paired that with a billet machined connecting rod that comes with bearing inserts. The pistons are a 12.5 CC dish and with a stock .040 gasket and stock not machined cylinder heads the engine will have a 9:1 compression ratio.
