Could anyone run this infor in desktop dyno for me please. Or give me your guesses.

460 with ported heads (not extreme port job, but decent)

edelbrock performer rpm intake manifold

LandL headers

Edelbrock performer 750cfm carb

Dual Flowmaster 30's series muffler/exhaust

Compcams magnum .530 lift .230/.230 duration at .05 280/280
total duration 110 degree lobe separation

edelbrock roller rockers with 1.73 ratio

 

I need to know the compression ratio and was it bored any.

 

figure 9.5:1 and no bore. Thanks.

 

Ok, I'll have to do it tomorrow. I haven't brought my desktop dyno home yet. Look for an answer tomorrow by lunchtime.

Well, my numbers came up as such: 421 HP@5000 rpm and 484 lbs tq @ 4000 rpm. These are approx. numbers but will put you somewhere in the ballpark.

Eric, I emailed you D3VE flow numbers with a 25% porting increase on the exhaust side for use with DD. The cam you're using should peak at 6000rpm on the hp side on DD. Sorry, but I didn't save the DD file.

 

I don't if this site will anyone but I hope so.
