Post subject:  exhaust around oil pan

My 1938 Plymouth has a 74 Duster 225/6-904 being installed in the chassis. Dues to chassis x member clearance issues, there is no room for the exhaust to go down the drivers side of the engine/transmission. I was considering running the exhaust under the oil pan with a way to "split" (take apart) it if there was a need to remove the pan. Any ideas for heat wrap, heat shields, connections, and clearance distance needed. Any other suggestions would be appreciated.

Welcome to the site. Sounds like a super cool project. I believe Aspens/Volares had this format on Slants, under the back of the sump and to the pass side.

I would keep it 0.5" away from the oil pan and use thermotec heat wrap tape (attached w/hose clamps or stainless zip ties/clamps) in the area of the oilpan. I have had one tube of a header bump/rest against the driver side of the oilpan at one point and had no ill effects.

Happy building,

Lou

On the F bodies the exhaaust crosses under the trans for slant 6 models - after the bellhousing but before the auto trans Pan - I have no Stock slant 6 F bodies anymore, but I think that is where it crossed over.

I would definitely look at the F body crossover pipe.

You might find a stock pipe that fits. That's good as they are larger than earlier setups.

You can't tell by the diagram, but the F body slant exhaust does cross over to the passenger side. Basically goes under the oil pan in front of the trans. That is how my Volare wagon was.

That routing is correct. I still have the stock super six "header" from the 78 Aspen and it's 2 1/4" for that pipe...
I use this same header configuration as the rear on my dutra duals if doing true dual pipes.
