Does anybody have a pic of how close the exhaust collector is to the back side of the gas tank . And what type of clamps went from the transverse muffler pipe to the collector pipe on a 1970 GT 350 . My collector is very close to the back side of the tank is this correct . about 1/2 inch . Also I my have many questions on wiring routing trying to get this Shelby back to correct as possible . Has a very nice restoration 10 years ago but mickey took over at 90 % completion stage . new to forum , New to me Shelby . Thank you
About 1/2 inch at the top and a 1inch at the bottom of the collector in relation to the gas tank is normal. Yes it heats up the tank. So does the transverse on the front side of the tank . That transverse distance is only about a inch at the top and 1 1/4 at the bottom . On the GT500's it effected things enough to cause a few fires from the heated gas tank fumes coming out of the vented gas cap to be ignited by sparks from exhaust back fire. The recall fix short answer calls for a non vented cap and a adding a vent tube to the gas filler neck and routing the tube through the trunk to frame rail . That should have been incorporated into the GT350's also IMO. The 69/70 exhaust port is very cool looking IMO but a very poor engineered design given what it does IMO.
