Description
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 8:1 compression ratio.
