Are you uesing 6" rods? I have and its worth it.... As Smokey allways said "The longer the rod the better". I built a srtoker for a buddies 57 Vett and all he wanted was to spank them 5.0s. I bought the kit from DYNA FLO and we had to detune the beast to drive with it in 4th gear. Out of about four SBC i've stroked the long rod motors were the shit. Price wise there isnt much difference.
