ooo thank you thank you for the pics nitrous!!
Yeah, i have an LS1 block that threw #7 rod through the block, i can use it to measure and then my stock cups. So they just share that one bottom center hole? NIiiice. The stainless looks nice. Would a huge chunk of aluminum that was milled out to bolt the 4 bolts to the LS block, then perpendicular 2 ears for the frame side mount be feasible? Perhaps with steel bushings on the "ears" going to the frame mounts? One piece from the frame mount to the engine block humm...
