It would be helpful to know the intended hp range although 200gph is more than the stock merc pump and I'm pushing 700hp.

I have the same engine essentially....30 over 454 with and 8-71....I have dual holley 850s and run this pump at 9 psi and so far its been working great...had some other engine issues and haven't been able to run WOT for a long run but when I did run it WOT for 1/4 mile or so a few times fuel pressure didn't drop a bit...here's a link

No need to go electric. Those pumps will work fine assuming your using regulators. On the flip side the Baker/proCam pumps are commonly used flawlessly and plumbed right you can get away with one without needing a regulator. I think it's the 9373 if I'm not mistaking. They maintain 7-9 psi. Otherwise you can step up to the next one however requires regulator. MT and others with sc builds in the 800 hp plus range do just fine with them. Well planned out fuel hose/fittings is key. Icdedpl had some blown 548, in the 900 hp range and experienced low pressure like 2 pds + - during extended runs with the 9373's but your likely not going to be in that hp range.

Dont get me wrong those are very nice billet pumps budget permitting. You can just do the same job that's proven for much less.

The 9372's solved Dan's problem I believe but he can verify. I'm going by memory from old thread. Again The 9373's plumbed right you'd be fine. You can do math on gph. 130 more than adequate. You should be fine with stock needle and seats but something else to consider stepping up just so you don't drain the bowls.
