Not Ranked
Just an FYI. I have built several 428 and 427 engines and the key to keeping your engine running cool is to NEVER over bore the block beyond .030. I have owned engines that were bored beyond that tolerance and they would heat up going throug a MacDonalds. The fastest engine I have had in my cobra was a 428 bored .018 over. I put over 4000 race miles on it and regularly drove it in town with NO heating issues.
As far as Shell Valley, Dana and the others build a nice product and have been improving on it for years. Plus their customer support is spot on. I have never owned a SV but have driven many of them and a good rule of thumb on any Cobra is be sure you are putting the best components on it you can and be honest about what you want to do with it......cruises, Dairy Queen Runs, Track Days, etc. these things are head turners and ego inflators so be prepared to enjoy the ride.
