Proposed 400 bb build, cam recommendations

The 400 needs high compression
Agreed. Not 13-14 to 1.
(custom pistons)
Disagree. KB still sells flat top hypers. Use with small chambered heads for a reasonable ratio.
to deal with the size cam it would need, let's say a minimum of 255 degrees @.050 and a roller.
Roller need not apply. If somebody out there (not you) thinks a cam of 255@050 isn’t streetable, please take off the big boy pants and out your dads shoes back where they belong.

Atleast 300 cfm of headflow.
Indy EZ heads. TF heads. Touched up Edelbrock’s maybe? IDK there.
600 hp in just a 400 will need to spin way up to make that power like 7000 minimum,
Really?!?! I have some people for you to meet. Besides, is 7K deadly territory? I don’t think so.
a pretty damn high converter.
A modern well built unit would work very well here. Speak with Lenny @ Ultimate
That's not Brooks 600 HP stop light to stop light I don't believe he's go to driving a lightweight car either
Well, he will make the call.
I don't believe a pump gas compression 400 would be hitting 600 in the area of how he wants to drive, remember he wants nitrous too.
I have some old friends I want to intro you to one day.
When they Liz’s there pants s laughing at you, you may come around a bit.
I'm going by what Andy f has tested .
Unless IQ52 has done it, I don't buy it.
Let’s take the other fellas out of this a minute.
Your not buying what?
A 400 B engine with good heads and a well thought out plan can not make 1.5 HP per cube?
If so, I’m done here and out.
Have - A - GREAT! - day.
