Well, i just installed a mini ram II intake and corvette heads with bigger valves and bigger springs. I set the timing around 10 degrees, and around 2,000 up to around 3500 rpm's the car somtimes bogs down, and just seems like somthing is wrong. But once the engine rev's past 3500 it seems that it works good.
Some one please help. thank you.
Also i was wounderin how cold is too cold for my engine to be running? thanks
