My trip to the track...

It will be interesting to see! I love test and tuning! I dropped 4 tenths once on a high 13 second car by going from a 750 vacuum secondary (without the rear metering plate) to a 750 holley double pumper. If you are lean from the 60', your whole ET and mph suffer.... This time of year, heat and humidity in the St Louis area will rob E.T. and mph too.. Keep her cool... :)
