SVT short deck alloy blocks weigh as much if not more than iron early blocks, due to extra webbing on the cam towers, thicker main webbing, and in other areas. However, they can be bored to 4.6 bores safely for a big bore street engine. Believe it or not the lightweight factory block 385 out there is the late truck FI iron block, but they do not take kindly to the bore bar. I'm presantly workling on one of those .020 over guys, and with dubeous use of a grinder, deck cuts and other machining cuts, I've got a late bare block down to 168 lbs with stock caps. Dependent on the many build weight factors out there I assume a stroker long block could be built at around 450 lbs with this block, if that is the way you want such a engine built.
