Need some 225 V6 exhaust info! - Pirate4x4.Com : 4x4 and Off-Road Forum

I've got a '53 Flattie with a really crappy, broken set of fenderwell headers bolted to the swapped-in 225 V6. I'd really like to ditch all that, and swap back to a set of factory type exhaust manifolds and run a single exhaust system.

I've seen that the factory CJ5 V6 style manifolds both ran forward to clear the steering and related items. I've also heard that a pair of passenger side manifolds will work, just put the one on the driver's side on so the exhaust dumps forward

I can see what they were talking about, but will that even work? Are their bolt patterns the same backward & forward? If so, can I just buy 2 passenger side manifolds from an 80's RWD model 231 equipped passenger car and have them work with relative ease?

Also, I need to add that the Flattie has a Saginaw box swapped in, too. Will there be issues with clearance?

I had a 225 with the same problem. I ended up converting to a newer style exhaust. I used a pair of manifolds from an early 80's Olds wagon. The driver side manifold feeds almost straight down and is very tight to the block. There is a cross over tube that then feeds into the passenger manifold. At this point all you need to do is run a single pipe off the passenger side. Works slick. In fact, it still in my rig all these years later. Although it's now an even fire motor. This set up should clear just about all you have going on under your hood. The same set up can be found on Regals and whatever the Pontiac version of the car was. It should be much easier to find than odd fire Jeep manifolds.

willysworker- what kind of paint did you use on that exhaust?-seems to be holding up well!

I really don't remember whats on the exhaust pipe other than it was very high temp spray can stuff. the manifolds are Eastwood brush on.
