Hey guys i recently installed a summit OE replacement oil pan on what im pretty sure is a 77'-79' olds 350 in my 87' cutlass supreme. Now the crossover pipe for the exhaust doesnt fit. It seems the sump of the pan strectchs forward more and doesnt allow clearance for the crossover to reach the flanges on the manifolds. Now id love to swap to headers but i just dont have the money for that right now, so what would be my best option?
