just a random ?
you stroke the engine to get the size you want and then bigger pistons, i cant remember what combo it is to get 383 but alot of people run 408's
and to be spinning an engine at 8grand like that for long periods of times you need to have top quality parts in your engine, that valvetrain needs to be light or else you'll start floating valves, i had a thead aboug 3 year's ago where i was asking the same question, but for a SBC gen 1, i'll look it up
