I will try to explain the problem to the best of my ability.
Background: 89 shortblock, tfs1 cam, edelbrock rpm air gap dual plane intake, Quick Fuel 600 cfm vacuum secondaries carb, new duraspark dizzy, msd6al2 ignition, t5 trans.
The timing is set at 16* initial and 36* total. I have changed springs so the timing curve comes in fairly quickly, total timing around 2800rpms. Carb was brand new (still learning about tuning a carb).
The car drives well under hard acceleration, but not during normal driving conditions. The car falls on its face when you take off easy from a stop sign type situation and doesn't want to accelerate until you give it 3/4 throttle, then it comes on strong.
Also does not want to cruise at a steady speed with steady throttle at lower rpms (under 3k rpms). But it likes to be over 3k rpms and more throttle. I'm still learning a lot with this build, but I'm stumped. I've played with the timing, messed with when the secondaries open, etc. I want to be able to drive the car 50+ miles without fighting it. Any help or guidance is greatly appreciated.
