Topic: BSO / Olds 307 manifolds
I'm looking to help address what seems to be an exhaust clearance problem. The stock exhaust manifolds have a crossover tube beneath the engine and the passenger side collects it and then shoots it out rearwards. This won't work with the firewall clearance. Is there an alternative Oldsmobile pattern exhaust manifold that has it coming down instead of pointing rearward and without the crossover pipe? The alternative is to cut the rear facing flange off short and weld it up (yea, welding cast iron) and using the crossover portion as the exhaust exit.
Any budget-friendly suggestions?
