Chevy 400 Build

If you go aftermarket, you cam usually order the heads with steamholes, or have a machinist drilled them.

Have you ever road in a car with 600hp? Or 400hp? The rest of the car also means a whole lot. You still want AC? and 600hp and nitrous? Im not insulting at all. My advice, dont get caught up on a number.

I found some complete vortec heads that are stock and still have the springs and rocker arms still on. For 200 bucks. I know im limited to a .480 cam lift. With stock valves in these heads what kind of hp can I expect? I plan to get them ported

Is it true that I cannot run vortec heads on my build because of the Speed Pro h616Cp pistons? Machinist told me in order for me to able to run vortec heads I will have to run air plane or 100+ octane fuel? Whats the best stock head to use...to get some power and to be able to run pump gas??

I hope someone can confirm, but
I've heard you need to run 5cc dish pistons. With flattops, there is to much compression with Vortec 64cc heads

I wonder if you could get away with a flat-top piston combo if you use a very large duration cam, which will bring down the dynamic compression ratio.

I was looking at some of my old posts and this one came up as "most active topic" so I was wondering how this engine build turned out.
The OP is still on here and I for one am curious if it ever ran or did it blow up or did he give up?
My inquiring mind would like to know.

Ended up selling the engine because i had to move no where to store it... Trying to find me 350 block now or rebuild this sbc 305 I have. I should of kept the sbc 40 but I ran into problems where my rod bolts have to be mocked up because of the cam hitting them
