how much horse power

[Every Detail]

How much power do you think this combo will make?

--------------------------------------------------------------------------------

The block is a large journal 327 with scat 5.7 H- beam rods KB .030 125 step forged domed pistons,the block is 0 decked every thing is ballenced ,ARP every thing,fluid damper. I put a trick flow top end kit on it that they dynoed on a 383 with flat top pistons and it made 490 horse and 440 torque. My qustion is what the power diffrence in the cubic inches? The cam is hydrolic with246*/254* duration at .050 lift .495"/.510"with 1.5 ratio rockers,112* lobe separation. The heads arehttp://store.summitracing.com/partdetail.asp?part=TFS%2DK314%2D490%2D440&autovie w=sku alluminum 72chambers,195 intake runners,2.02 1.60 valves. Victor JR and 750 speed demon,Msd 6al2

Sounds like the combo we just did in Camaro Performers.

We had a 327 short block. stock deck, 60 over bore. I don't remember the cam specs but they were less than yours. Had the Trick Flow intake and a Holley 750 carb. Also, the compression was WAY low.. like 9:1 (to run the cheap gas).

I will post the results on monday but I think it was 394hp and 370 tq ... your combo should make a bit more, defiently into the 400s.

thanks some guy over at nasty z28 told me I was only going to make 360 horse,this motor stock made 365 horse[68 Vette)Plus I also have a Zex perimeter plate nitrous kit that i'm going to run a150 shot,should be a little screamer

That's a lot of cam for the cubic inches. What's the compression ratio?

10.5 to1

Using Pat Kelley's DCR calculator, 6.92 DCR. Maybe too much cam or not enough compression, particularly with aluminum heads.
