has anyone tried the alum. manifold kit from Moore's performance? Can't afford really expensive stuff.Seemed like bang for the buck these might be the way to go. Stock 454 330 horse.

They are great if you are looking to replace stock pieces. they weigh a lot less but no performance gain in power output. Gain will come from weight loss. I would get a set of revolutions or buy a used setup. I made the mistake of trying them and then replacing them with a real set. they are well made and light but you can get a good set of real mainfolds for a little more money
