What CC are double camel hump heads?
When I build a motor, what the block came out of or the heads off of doesn't mean much if anything.
What I do to them changes them so what they are off of is insignificant.
I cc all heads and cut them so all the chambers are the same. Curious where yours are to net a static 10.5:1
I have built lots of SBC's but I am really not into them personally so I don't know all the small block lingo.. sorry about that.
What deck height do the pistons come out to?
What are the valve springs set up to? Height and tension? 69 Z28 doesn't mean much to me... sorry
To come up with .490 lift on a .445/.465 cam, 1.65 rockers, right? That would/should get you 490/500 lift.
Did you have the heads ported? I hear so many people talk about porting and polishing street heads... polishing helps the fuel puddle at low RPM and that isn't good. Porting is all that needs to be done on street heads.
3000 stall speed would be kind of a drag (old school term for not nice) to drive on the street. 2600-2800 should be fine as it gives the motor 400-600 rpm to spin up while the cam starts working but frankly the "specs" for where the engine works is entirely dependent on what combination you are using in the motor.
Torque rating is a huge denominator in engine design as well.
Your motor sounds healthy in the video I saw. However, to make over 400 hp your mouse motor needs to make about 1.25 HP per cubic inch... that is significant.
