How much HP can I expect?
« on: May 20, 2009 - 07:51:51 PM »
Here's the package. Anyone want to give me an educated guess on the HP?
Hemi with stock cast iron heads.
Stock bore, 4.15 stroke (472 CID)
6.86" Eagle rods
Eagle crank
Diamond pistons 10:1 compression
Custom Grind Cam 0.547" intake, 0.540" exhaust lift
254 deg intake duration @0.050" lift
246 deg exhaust duration @0.050" lift (110 degree centerline)
2-1/8" Hooker super comp headers
2 different induction options:
Stock 2 x 4 intake and carbs or dual plane mopar intake with 850 Holley

What do you think? Is 500 HP a reasonable estimate?

500 sounds pretty conservative. I'd say closer to 600.

600 would be fun. I sure hope I didn't get carried away and over do it for a street car.

Sounds like a pretty solid street package to me. I would guess 600 Hp also!

Probably 575-600 or so at the crank.  Closer to 500 to the wheels.  Sounds like a good setup....    :2thumbs:
