How much power can i get out of a 400 with stock heads with a mild port job?
What cam?

stock...250?

stock 400 heads typically suck...don't use them because you won't have any compression with stock pistons, and they have smog combustion chambers. They'll make your engine into a boat anchor.

Stock 400's have real poor heads, restrictive intake, low lift cam and low compression which limits the HP potential.
I would at least switch the heads. With 64cc heads you'll boost the CR and greatly improve air flow which is the essential building block for power production.

K so how about a set of ported vortecs that i already have?

with ported vortecs and the right cam you can get close to 400hp
