While procomp has some iffy products out they seem to be aggressive in terms of marketing and designing new products. That is a heck of alot more than edelbucks can say and the rest of them! The thing with aggressive companies is they usually get bigger and better. Until the manifold is tested and determined a piece of junk I will give them credit for going where no one else seems to wanna a go. There has been a few companies that have surprised even the crustiest 351c enthusiasts on this forum!
