OK, so after much searching and self debating, I'm going to rebuild the 390 and put it back in the Campbell.  So, I have a little question about what cam grind I should go with.

After playing with the desk top dyno for the last week or so I've found a combo that seems will work well.  

Motor specs: 390 .060 over, Speed Pro flat top forged pistons, composite gaskets with .038 compression thikness should yeild about 11.5:1 compretion.  Offy high rise dual plane manifold and a holley 750 cfm double pumper.  And of course a mag.  :D

Cam specs are: Mechanical .559/.572 intake/exhaust on a 106* intake centerline and 300*/310* advertised duration (237*/247* duration at .050"), Lobe seperation is 110*, but while playing on the dyno if I stretch it to 112*, the torque curve really flattens out accross the opperating range of the cam.  

On the computer, this combo yields 494 ft/lbs @ 3500 and 423 hp at 5000.  the torque curve stays flat between 2500 and 5000 rpm (within 40 ft/lbs).

So, good bad, any suggestion??   :stupid

Do you want the cam file, or the entire motor file??

I don't have an airflow file for the heads, that would help alot.  I'm using the "Wedge/stock ports and valves" file with stock valve sizes.

You can just send the motor file, I've got their "Cam' disk so I'm sure I've got the profile!.. :good Yeah without actual flow numbers it's hard to zero in on it but you can get a good ballpark figure good enough to give you an idea of what you'll have!.. :good

Well, I tried that and it allows me to email you from here, but no address.  And I can't attatch a file from here either.   :beat

Could you pm it to me, please??
