Desktop anyone?

I just got my 466 together and was wondering if i could figure out what kind of horsepower and torque this is putting out. It is making 9.5 to 1 compression. Cam has a cam with duration @ .050 Int. 216 Exh. 228 and lift at Int. 518 Exh. 513. It has a Holley 750 double pumper, Weiand stealth intake. And schoenfeld tractor pull headers with 2'' primaries and 4'' collectors. i dont have any exhaust system...just the straight headers. The motor is bored .030 over. If anything else is need let me know...thanks alot in advance

What heads? Any flow numbers on them? Having actual flow numbers is the way to get the most acurate horsepower and torque numbers.

Ok, using the flow numbers from a stock set of D3 heads, no porting and stock valves, I come up with
335 HP @ 4000rpm
525 TQ @ 2500rpm

Desktop Dyno 2000. When using actual head flow numbers it is pretty close to right on.

What cam are you using(manufacturer and part/grind number)? If I'm reading right, your cam has more duration and lift on the intake side?? This seems odd for a BBF cam. Also, is it a solid, hydraulic or roller cam?

It is hydraulic, and the specs are correct. It's a custom hydraulic flat by Lunati Cams.

OK.

524HP @ 5500 rpm
572TQ @ 4000 rpm

What are the lobe sep. angle and intake centerline? I entered 110 degrees on each for these numbers.

Intake C/L is 112, and Cam is mechanical, not hydraulic, I wasn't paying attention to my own post.

Wow, that is weird. The solid cam makes less HP but more torque than the hydraulic. Here are the new numbers:

506HP @ 5000 RPM
620TQ @ 3500 RPM
