If you are looking for performance, suggest you look for an early Navarro, either the racing model, or the street version. Read the recent test in Hot Rod magazine.
If you read old articles on Eddie Edmunds, you will find he was a promoter making stuff so your car looked good. Performance was not the purpose of his products. He is not even listed in the book on the early speed parts mfg.s, "Merchant of Speed". Edmunds died at an early age from personal abuse.
