If you're looking to go as far as we consider practical in stretching the Small Block Fords capacity, then the Big Bore 363 is your combination. Based on a 4.125 aftermarket block with a 3.400 stroke crankshaft this setup will allow you to achieve torque numbers that are not possible with smaller motors. The better the heads flow, and healthier the camshaft is, the better this setup will work.
Flat Top
Flat top pistons in a 363 Ford 4.125 bore engine will generally provide compression ratios in the 10.6:1 range which makes them a good option for engines with cast iron heads with at least 72ccs, as well as any engine with aluminum heads. They are boost and Nitrous friendly and have valve reliefs configured to work with most types of standard and aluminum cylinder heads and will normally fit camshafts to slightly over .600 valve lift.
