Hi! Been out of this stuff for many years, need some help. Just got a street 72 nova with 502/502. 1.It's got Delco-Remy HEI. Should I help this with an MSD?
2.Has electric fuel pmp. How much pressure?
3.Has an Exh. gas temp. guage. How's, it used -tuning, jetting?
4.Says valve adj. is zero lash- No more 3/4 turn?
Thanks -CorbCorb
Welcome to CHR. I think that you need to hook up your vacuum advance. At part throttle when cruising you have less air and fuel in each cylinder, and the air-fuel mixture is not as densely packed...
