300/350

Wondering if the exhaust manifolds or anything else would interchange 65-300,70-350.jim

 

Or if there are any shorty headers out there.Jim

 

Manifolds/headers will not swap between the 300 and 350. They are completely different. There may be some shorty headers out there for the rover stuff..
