Finally got some dry weather so I could drive the car and check the secondaries. The secondaries were definitely not opening. I had a new vacuum diaphragm so I installed it with a yellow spring, secondaries still didn't open. I have a 750 double pumper i'm going to throw on tomorrow and take it for a ride. Should make a huge difference. Ever since I put the crate engine in the car it just spins the street tires at the hit of the pedal so I never really knew the car was down on performance until I put some slicks on it and made a few passes. Hopefully I can make it to the track again before they close for the year and see what the car runs with secondaries working. Then I'll have a converter built over the winter, possibly switch to a dual plane intake and 3.91's. Thanks to everyone for all the advice.
