So I'm am going to go over there tomorrow morning to 'hear it run'. I'm a little disapointed that I didn't get to be there for the actual 'dial in'. He said the Tq. was 497 & the HP was in the 450 range {he didn't have the dyno sheet in front of him}. Well I was hoping for more {OF COURSE, what hot rodder in there right mind would want LESS HP???}. Anyway, I'm just wondering if there is anything I should ask them tomorrow??? In regards to what did they or didn't they do or not do to 'tune it'??? I should ask to see a 'full power' dyno pull, shouldn't I??? Is there any info that I should get from them in regards to; the temperature that day, etc.... And I will ask for a copy of the Dyno results... I guess I'm just disapointed because I thought it'd put out more ... ANY feed back at all would be great Thanks Everyone, Bill

motor is; 413 small block, AFR 195 street heads, 10 to 1 compression, 750 double pumper {gone through by the Carb shop}, Edelbrook Air Gap RPM manafold, cam is Comp Cams, 490 lift w/ 1.6 rockers, 230/236 duration, 4/7 firing order..... Thanks Again ;()
4/7 swap firing order on a hyd. cam?Did I read this correct?
I am not sure what hp levels you wanted but this is not that far off.
To get over 500 hp you will need a hdy. roller cam or a mech. roller cam.
Heads,intake, carb. looks good to me.
