First, can someone post the idle RPM and Vac. numbers for a regular 7 engine? What does it sound like when cold and warm?

Secondly, can someone post the idle RPM and Vac. numbers for a street-ported engine? What does IT sound like when cold and warm?

Also, if you think any other factors (mods) contribute to any type of different numbers, please post them. Thanks.

 

i think my idle is high.....im not sure, someone tell me if it is or not. but mine is:

idle: 1100-1200

 

Hmmm, my idle is 1.5K rpms and I get 17 vac. on the boost guage. I'm trying to figure out whats going on.

 

I believe a normal stock FD should idle around 750-850 rpms (once warm) and the vacuum should be 17-20 for a non-ported motor (depending on altitude).
