The link above will take you to the GM parts page for this manifold.

 

Any interest or offers?

 

Very interested here. How much would shipping be to 46746 in Indiana?

Im looking to build my 305 (or get my hands on a 350) into a high compression ethanol burner with vortec heads and this would be ideal so i can keep my edelbrock perf carb.

That sound unreasonable?

Thanks
Jeff
