For folks to make educated guesses at.... power of 440

[Hot_Rodder]

I've been bored here lately... And though up of a combo for a buddy. I asked a similar question of this build and it's pretty much finalized as listed below. The question here is, for those who can guess fairly close to the power of a motor given certain engine spec's, I'm wondering what they think this would possibly put out around... Here's the general outline of the potential build:
Factory block (we will say + .030 for the purpose of this question)
Factory crank and factory rods
Flat top pistons (compression right around 9.5:1)
Factory 452 heads, untouched
Lunati VooDoo 60303 cam with matched valve springs and such
Cam Spec's are listed as: .494/.513    226*/234* @ .050     110* l/s
Holley Street Dominator intake with a one inch four hole phenolic spacer
Factory style electronic ignition
Heddman Headers   1 3/4" primary tubes with 3" collector full length tubes
850 cfm carb, vacuum secondary electric choke
K&N X-stream air filter assembly
aluminum high volume water pump
electric fans assembly
factory style rocker arm assembly
What else is there.....
So, what do you all think the potential #'s could be... As of right now the heads are untouched, but might do a little gasket matching just to help aid things, but for this purpose assume untouched heads.

I agree.

However,
That combo could benefit GREATLY from some mild Bowl Porting, and Comp. Style Valve Seat Angles with a Back-cut.

I believe 410 is conservative,  425 to 430 if it is tuned right.

I agree! I also think there is another 50 horse just waiting to come out with bigger valves and some bowl work.

I also agree with the above estimates. That 410/475 power number might be a little short on the torque side but in the "real world" it's fairly accurate. Don't believe everything you read in the Magazines....especially if it comes off Westech's dyno.....

The above combo wasn't based on anything that I had read somewhere. This was just a warmed up build on a factory motor pretty much. Not trying to build a race car, just something with enough power to where it can get out of it's own way should the need ever arise. If I were going power hungry type status then it would completely different, lol.
