Exhaust Clearance

I have a Model A with SBC and Sanderson Cast Manifolds that dump straight down. Tha header pipe is about 1 inch from the aluminum fuel line that is mounted inside the frame rail. Is this too close? any suggestions. Thanks

Unfortunately, with a SBC in a 1928 to 1934 Ford chassis ... that is common. My 32 right side exhaust is about 1 and 1/2 inches off the frame rail.
I always try to have the exhaust pipe coated with a thermal heat barrier. Like Jet Hot ... It really helps keep the heat down around the pipe and it improves the appearance too.

Make up a thermal barrier from 2 sheets of aluminum cut to the size they need to be. Use washers, bolts and lock nuts (not the ones with the plastic insert) in several locations between the 2 to make a sandwich about 1/2" to 3/4" thick and mount it between the pipe and line. The plate next to the pipe will get hot as the hubs of hell, but the air between the two plates will prevent transfer of the heat to the plate next to the line, particularly if you mount it so that air passes through when you are moving. Problem solved. For cheap.
