Can someone explain stroker kits

That's why I try my damndest to preach to learn to do ALL you can yourself and SAVE some money. You can almost cut the price of a big name stroker build in HALF doing a lot of things including assembly yourself. Being broke all the time, I never understood why people would rather put a dent in their bank account than do it themselves. Plus, that gets them even MORE into the hobby. Those that pay for everything seem more like posers to me.
Rob,did all my own work,(clearances to .060" on rotator\ block clearances, side grinding shot peening stock rods..That was '06-07 prices,with roughly 7000-7500.. Flat tappet hyd cam,home ported Eddy heads....) You find a 408 short block,maybe 3.5-4 k,I wouldn't trust a crate block...
