Ive heard the same but want more input/ideas/suggestions. My last engine made 800hp and I ran a bronze.
The bowl is another question. Are there any bowls I should stay away from?
Honestly, at even 1000 HP I doubt you could hurt any of the "name" bowls > Berk, AT, Aggressor, Dominator. I would however switch out any bowl bolts to studs
Believe I've read here, there was some casting flaws with a few Aggressor bowls but those were behind engines that made a few serious thousand HP.
Sounds like you got a serious motor, any details on it?
You ought to bring that thing out to the drags once. It's a good place to dial in a setup like that. As far as the MB, from what I've been told you should be fine. But I would call a reputable pump builder to be sure.
