wow those look good with that stroke. just seems like a 3.79 and with a 1 688 r/s ratio would eliminate friction and binding to possibly make more power with a small head than a 408 and make the stock block last longer. the factorys use the 3 3/4 stroke in a lot of different engines for a reason and there's a lot of fast motors out there using that stroke. almost like a magic stroke, that's why i'v been stuck on that stroke, but i'm open to all opinions or info here. currently my peak hp is at 6600rpm using a 260/269@50 .700 lift roller.
