need some opinions - step in here

i know i know this question comes up a lot.
how much HP you think this engine is making?
it is in tip top tune and shape, and i think the cam has more lift then is stated in the paragraph below. how much HP at the flywheel? at the rear wheels?

It has 2.02 1.60 heads. The heads have screw-in studs and guideplates. They are also ported and polished. It has a 275° duration camshaft. The engine is fully balanced and blueprinted, and the deck has been trued. Its got side polished shot peaned rods with ARP bolts. Keith Black flat top pistons. I'm running a Weiand Stealth intake manifold with a Holley 600 CFM Double Pumper carb, without the choke tower. The car still has the stock converter and tranny, but it has 3.73 posi in the rear-end. The stock LCAs are boxed. I have a Stewart Stage 1 water pump. For the exhaust there's Hedman headers with their y-pipe. The y-pipe has been ported and the single 2.5" pipe is now 3". Its got a straight-piped cat and the single 3" goes all the way back to a 3" Flowmaster 40 series race muffler with a single hideaway tailpipe. There are some poly bushings around, and thats all I can remember right now although I'm sure there's a lot more.


thanks

You're gonna have to do a lot better than that

But, judging on JUST what was stated - not knowing the grind of the cam or what heads you have...
I'd say between 250-375HP

Marc is right, more cam specs needed. ie exhuast intake lift, lobe seperation....etc sounds like around 300 at the rear wheels with a nice cam set up and could very well be anywhere from 345 375 at the flywheel
