Here are two other suggestions that would probably work well if it is heat soak . I run a wood insulator under the carb that is readily available from Summit in various thicknesses . Seems to work better on my FE that the shield for some reason .
Another area that is generally overlooked is the fuel pump . It`s sitting right against the hot engine block and is lubricated by hot engine
oil . I found a company …… Seals - It , who makes a fuel pump heat insulator gasket set that they came up with for Robert Yates Racing for their Windsor engines .
It consists of a special insulator gasket , insulated bolts and a hot
oil shield that keeps the hot engine
oil out of the pump . Since the fuel pump is lubricated with splash engine oil , it obviously needs some lube from somewhere . So , they installed a grease fitting in the pump body and pack it with grease .
I put that setup on my FE minus the seal gasket . Even though it`s an FE , the gasket fit fine with no leaks and only moved the pump out about 3/16” . No problems with overstroking the pump with that small a change ( I installed it , turned it over some , pulled the pump off and checked the ride pattern on the pump actuator arm ) . This kit is also available from Summit for around $50 to 60 US dollars .
Just a thought .
