The carb is borrowed so unsure of the jets probably factory its a holley 750 vacuum secondary.the cam us a comp extreme energy. 12-677-4 advertised duration 274/280 with .501/510 lift and i have 1.6 roller rockers.i know carb had a kit in it last main concern is i have been told the ar134 plugs are not a hot enough plug for the compression i have now.on new plugs car runs good 8.15 in the 1/8 at 86mph but after 20 to 30 passes plugs are dead .wondering if a different plug would help this.i would like to stick with autolite if i could.
