First, since someone will surely ask, and because i know this is a frequent question, i have already done a search, but i figure it's easiest to just ask again with my specific set up. The question being, what size mainly, and brand suggestions are welcome too, should i top this engine with. I know i should really have all of the information before i ask, but i can't find my cam specs right now, and will post them as soon as i find the card...but here's the rest.

flat top, forged pistons
RHS 64cc vortec style heads, pocket ported
2.02, 1.60 valves
cam? fairly large lift, at or just under half inch lift if i remember correctly, no recolection on duration, sorry.
Hooker shorty headers
Stock HEI
Edelbrock 600 cfm carb currently
Holley Keith dorton signature series intake
summit 80 gph fuel pump...no regulator.

Also, do i need to get a regulator in line? should i get one with a return line, or do they all run one? Also, any guess on what type of hp this might put out? (i know thats hard w/o the cam specs, again, ill get them asap)

Thanx for any input.

I forgot to say. This is a full roller engine also. with 1.5 rockers.

I assume this is your fuel pump?

If so, I think it would be fine as is..

Also.. As for the carb.. This is a 385? I would say go bigger. 700 or 750 would be better. At *least* a 650. I'll leave the Holley vs Edelbrock vs ..? debate out of this response.
