I am thinking about doing the big bore this winter and was comparing the options out there... I would like a comparison if the Weisco kit and the one South Bay has to offer.. I am leaning towards the one from South Bay simply because you dont ship anything out to be machined, pressed, etc.. You get everything you need in the kit... Also the South Bay kit runs at a higher compression ratio, 11.5/1 as compaired to 10.5/1 Anybody know anymore about these??? Would also even think about upgrading to the 988 kit that is offered since it comes with a pre prepped crank ( just turn in yours for core, like the juggs )
