how much hp

[madmax]

I have rules that state 485 cid and any cast heads with 1 carb any size. I am at 4.530 and 3.75 with a dry sump. What would be the max hp that could be reached with these rules and how? I run up to 8500rpm now so I am not afarid of some rpm. I just want to set a goal for hp.

Contact a good engine builder first, Because if you do not know how, I don't know anyone who is going to share this with you. As far as how much power realistically? 900 low side 1020 high side. Depends on what rules you have and how much money you want to spend. You can make really good HP with the proper parts and maybe even a touch more. The single 4 will hold you up a little.
