Anyone ever purchased parts from PowerHouse? I came across their ad in Chevy High Performance mag. They sell a 383 stroker kit that comes with a new crank, flat top stroker pistons, pro street style rings, new CR1 5.7 rods, main and rod bearings, and a full gasket set. $489. Add balancing, new balancer,new flexplate for $199 more. Just wondering about the quality of these parts. There web adress is enginekits.com All opinions appreciated.
