Jeff Balazs Posted August 9, 2016 Report Posted August 9, 2016 Here is a photo of the 1st version of my home made heat shield. Once I had tested this for a while I made a little larger one and that is what I settled on. As you can see it is a very simple item. I made it from some sheet aluminum I had laying around. Hope this helps, Jeff Quote
greg g Posted August 10, 2016 Report Posted August 10, 2016 My 56 engine had a piece (factory installed) very similar to that mounted the same way. You do need to double up on under carb gaskets and also be sure to provide a route to feed the vacuum port in the base of the carb that runs the step up jet or you will be running rich all the time. 1 Quote

Interesting. Perhaps this isn't just a modern day issue. I don't want to hassle with removing the carb again so I am going to try to rig something differently. Quote
greg g Posted August 10, 2016 Report Posted August 10, 2016 As hood lines got lowered by the designers, the manifold casting directly under the carburetor got lower and lower, as a result the carb float bowl got closer and closer to the exhaust manifold, so more heat shielding was needed as engineers tried to deal with percolation issues. 1 Quote
Jeff Balazs Posted August 10, 2016 Report Posted August 10, 2016 The second version of this shield I made has been on the truck for about a year now. I made it using two sheets of aluminum with 1/8" spacers in between. This shield is riveted together and is held in place above the manifold with baling wire. It can be removed in a moment using snips. It butts up to the carb base. As mentioned by others a good heavy (1/8") insulating gasket between the carb and the manifold is also part of this fix. Hope this helps. Jeff Quote

Worden18 Posted July 21, 2017 Report Posted July 21, 2017 This is what's happening to my car. I'll be fabricating a shield soon It pays to read these threads 1 Quote
