Thank for your comments.
I built my 383 back in '82 using a '74 350 4 bolt main block, 400 crank, stock 400 rods with modified ARP 350 rod bolts as the 400 rod bolts are a little different and you couldn't get Hi Perf 400 rod bolts back then and .030" over flat top cast 350 pistons. The shorter 400 rods will make a little higher peak torque than the 5.7" 350 rods but they'll restrict it's ability to rev a little, the longer rods will make a slightly flatter torque curve and let it rev a little easier. If you top it off with the same heads, cam and intake you have on your 350 or something very similar it's going to be very strong from an idle to 5500 and will rev to 6200 if need be. I had mine in a '72 Chevelle SS with a TH400 and 3.73 posi and it was a blast to drive but you've already heard all that.
Be careful though, after you get it together and running you're going to want one.
