383 <gasp> stroker runs <cough> rich
Yet another post on how to find the right carb and its settings.
1965 Chevy II Nova, 383 stroker, flat top pistons, 202/160 double hump heads w/roller rockers, Lunati hyd. 480 lift, 272 duration, Torker II single plane intake, HEI ignition (autolite 25 plugs, I think), Holley 750 double pumper through 1.75" coated headers and hooker turbo mufflers. Response through 5k is great, no hesitation, idles at 650, runs great (or did at the time).
Runs great if you can manage to see as your eyes fill up with tears because of the gas smell. It used to foul plugs frequently. I pulled the plugs this weekend and they are SPOTLESS (could the plugs have cleaned themselves through sitting?). I will run the car and check the plugs again, however, I am pretty sure I had the carb tweaked as best I could for the conditions. I have not re-jetted and can't remember what jets are in it (70 & 80?). Parts counter guy is telling me to jet for a 600 cfm. I have read a lot of posts about bigger carbs are over-hyped and most of the time not needed. Roger that, hind sight is 20/20 and I should have bought a 650, haha. I would like to make this one work before I dump 300 bucks on another carb.
The car has been sitting for a few years. I have changed the oil, filter, primed it, rolled it by hand, and am about ready to crack this thing off again. I wanted to get some feedback though, in case anyone would recommend changing jets or any other changes before I start it. Also, it is not a daily driver, but a weekend hobby, stoplight to stoplight toy. No prospects of a track anytime soon either.
Any help is greatly appreciated!!
