I'm not finding alot of sources for the speed-pro hypereutectic 383 pistons. does anyone have a source for the best deal on these pistons. Im pretty much set on speed pro as I dont want the larger ring gap of the KB's. also does anyone see any reason why these pistons would not be good for a mild 388?

350 4bolt main .060 over
400 crank
rebuilt 5.7 rods w/arp bolts
stock vortec heads
looking for approx. 9:1 compression
not sure of cam yet. will have to be under .450 lift anyway because of the heads, so I may reuse my crane 266 from the 307.
either reuse the 650 cfm edelbrock I have or buy a 750 cfm. not sure yet.
1 5/8 headers

thanks
