Edelbrock Streetmaster 318

As of lately if we were to believe everything we read we would all be putting #302 casting heads on our engines and running Street Masters. You don't see them on drag cars for a reason and you don't see him on any cars anymore for an even better reason.... they sucked outside of 4,000 RPM . They may be an improvement when bolted onto a stock engine but that's it and very limited amount of improvement to my knowledge
