engine and carb discription is in sig. right now there is 67 in the primaries and 77 in the secondaries what should i put in there for a basic start in tuning. i think 77 is too big for my application am i wrong?

From what I was just reading, with the dual plane intake, and the DP, a 77 in the rear might not be a bad thing. I would put the car together and run it. The jets are easy to change. I can do mine on my other car in about 20 min. If you drop the size to much it will hurt you alot. I tried it with my car and I was getting to much air and the car ran like sh*t. It should be fine, after all it is only a 600. Just make sure it can breath.
