5.7 and 6.1 are same stroke, so you would gain a forged crank using the 6.1 and its wheel. The rod lengths are the same as well. You can get rods in stock length, 6.242 IIRC, from a few different vendors like Molnar,K1 and Callies. Pay close attention because 99% of them use a .927 SBC pin instead of the stock .984. You can also get them in Chevy journal sizes like 2.0" which is what is going in mine,im not 100% sure but I think stock is 2.10 or 2.125. You can price a few things from these guys http://www.flatlanderracing.com/
