I am going to talk to Wiseco for the pistons.
Hello Gary... build a lot of 383 cid strokers for the street & strip...i use RPM's 4340 I beam 6.00 rods with ARP cap screws & Eagle & Scat & RPM cranks....# 2 cyln & # 6 cyln cam lobes are trouble ...these rods with lots to spare @ .500 to .650 lift...
BUT ALWAYS CHECK FOR ROD TO CAM LOBES FOR CLEARANCE ... RPM & EAGLE & SCAT cap screw loaded rods clear very well small base circle cam not needed.


Rod bolts clear blocks @ bottom of bores pretty good.... MOST clear BUT check all rods for clearance shoot for min .050th rod to bottom of bores.

Also watch # 7 & #8 rods for contact on side of block were dip stick hole in block is just behind that pad is a trouble spot.... also same area check crank counterweight for contact on edge of block inline with oil filter pad on block.
MOST cranks are very close or hit / rub on block ( OLDER BLOCKS WITH DRIVER SIDE DIP STICK)

Gary a good 4340 I beam rod 6.00 ARP cap screws loaded your looking @ $250 to $300 set prox... RPM OR SCAT ... EAGLE CHEAPEST.... also P/C has 6.00 rods cheapest @ prox $ 150 set....NO ARP BOLTS... i'd spend a tad more & go RPM /SCAT /EAGLE......... on a budget.

Pistons.... on budget KB claimers are not bad.... @ prox $220.00 set.... Forged we use Probe or Mahale... priced competetive.

PS: Also check your oil pan for clearance... rods to pan # 7 rod & # 8 again
they tend to hit pan side/ on right side of engine just behind that oil stick hole pad on block... take ball peen hammer & dimple out pan @ side were rods touch pan.
