440+Good cam+Good heads=LOTS O TQ

Here is a legit question?

How much does the hyd roller help over a flat tappet? Power wise that is - what would it make with a flat tappet with the same specs? Roller cam in one of these engines cost just under $1,000 with the right parts not including rockers

Those are REALLY good numbers for a head, cam, intake 440!

I hope to make 450hp at the crank with my HCI 383..
