Just got done installing a hydraulic roller 236/242, 114* into my short stroke 379 and was wondering what kind of vacuum signal at idle some of you folks are seeing. Haven't pulled it out of the garage yet, just got it idling, set timing, minimum idle, etc... I'm getting about 10 inHg at idle. This was an express elevator up from my previous cam so lots of tuning to do by next saturdays race. TIA

 

Which cam did you pull out?

BTW, I'll be seeing you next Saturday in Darlington.

Can't wait to see your car!

 

It was a flat tappet Comp Cams grind....12-404-4 I tihnk it was. 222/226 .464/.464 114* lsa. Yeah I should be there assuming nothing happens with tuning the car this weekend and getting a couple little things fixed up. See ya then.

 

8-12 is about normal, I get around 9-10 and a friend with the 236-242 was getting 10-11.
