like i said there two number for stock use . Auto wheels /flex weights are the same as the sticks for the ex cranks wheels as you can see there numbers for both engines heres Pep are 454#fwfp454l and 400/383fphd400 .Scat400/383scafp-400 and 454scafp-454. Pioneer make s both stick wheels for 400/383 and 454 used some new on both 383 /400s . just did some last summer with new fly wheels on 454/496 i build.i do many more set up for auto trans. so there is really no need to look only at only Gm for the stick wheels but here are the 400/383 numbers gm#3986394 the 454 Gm 3993827 and 3963537 lightweight wheel here is the cheater plates i do not care for them but here the numbers sbc two pc seal 400/383 fbp-2 the 454 two pc seal fbp-3454. we go threw alot of trouble getting the crank mass balanced under 2 grams if at time crank is balanced and is matched for flywheel so we try to used a wheel that is for the engine .like i said it may work but there 400 wheels out there should stick using it
