Ignition timing and cam Question,the good stuff
Hello everyone,
I have a 68 c10 swb with a sbc 350 with a muncie 4-spd shiften the gears. I have built this truck since I was 15, now in my old age at 20 I have realized some mistakes I made along the way. The motor is a 70 year, edelbrock performer intake, edelbrock electric choke carb 600cfm, headers, MSD HEI street fire dizzy, dual electric fan, roller rockers, comp cam XE274H . Cam specs: See attachment. I am trying to learn how to properly tune my motor because it is currently not running good. I recently realized that I cant just slap components together without any plan and expect them to work ![]() 1 st. I need to determine if the combination of carb, intake, cam, and Dizzy will work. 2 nd. How do I properly adjust my timing with setting the proper timing curve, advance, with the cam I have what full mechanical advance should I have and what advance at idle, and vacuum advance. Do I need a hotter coil or different dizzy? 3rd. How do I properly tune the carb. I have attempted jetting the carb numerous times but I feel that I need to figure my ignition out first. I also pulled and resealed my intake manifold to make sure I don't have a vacuum leak. replaced the sparkplug wires, added the heat protection sleeves near the header to save the boots from shorting out. I also wired my dizzy through a relay so it has straight battery power. Please excuse my terrible spelling I immigrated to CA from Germany in 07 Any suggestions or tips are already greatly appreciated. -Ben |
