Just a question about carb spacers... I have a 77 1/2 ton with a 350ci/300 hp and a mild cam, it is a crate engine. Was wondering what a carb spacer would do for me. I have a rochester q-jet with a edelbrock 2101 performer intake. My question is this.... Would it really performer like they say? what size should I get? I have heard you can make your own. Will it help the carb run cooler? i am looking for some more performance. Thanks for all the help and advise!
