CP Performance Marine has the 800 Marine Holley For Sale. Google CP Performance to find it. The specs between CP and Holley Marine seem to jive regarding acclerator pumps. I have seen 30 cc primary and 50 cc secondary and vice versa advertised in Summitt. The summit paper catalog also carries it. Mercury offers the carb with blue paint for $1200, Standard Holley Gold gives you a $700 discount.
I have blue one on 454 with blower. Great economy and awsome throttle response compared to running a 850 Holley.

Preuni if you go with the Quad . I have a fuel line that came off my 454 mag 365 hp if you need it?

I did the same swap because my 365 hp 454 with the carter would'nt start after only 20 minutes when hot. Starting fluid was needed after 2 days of sitting. I had to fab up some stainless throttle brackets and fuel line and also use a 1" spacer to clear the accelerator pump or it would hit the manifold. Did'nt notice any increase in top speed but think I gained some midrange and of course it starts if you just touch the key. Worth it to me!
