LT4 Hot Cam question
Hey all I am trying to tune my LT4 Hot 350. I am running S/A 770 with a proform HEI. If you read my other posts I am having problems getting it right. I know I had 18 to 19 inches with the LT4 cam. How many inches of Vacc. should I have with the HOT CAM at idle

I haven't measured it any time recently or with the new 730 Speed Density setup (and it idles soooooooo much nicer with the 730 setup), but I got right around 15" Hg with my 165 ECM running my combo.

Hey thanks man, I am not as far off as I think. I need to do some carb tuning but I am at 10 inches and have some valve adjustment problems. SO I am getting close.
Thanks
