I had a very similar combo 2 years ago....

Let's not forget a dyno is only a dyno, it will not tell you how fast you will be going...or how quick your car will respond....

May be a bit short on cam duration, but my realistic guess will be 475hp and 480lbs tq at 4800rpm

you have very good quench with those pistons, so a very efficient combustion chamber...

One way or another, you'll have plenty of fun !!
