I've got a stock 90 H.O. motor with a HEI dist. and I was needing to know where to hook the vaccum advance for best performance and no detonation,to the intake port or the timed on the carb?
I forgot to mention that the carb is 600 Holley. It has a timed port on the front meter block and a constint vaccum on the base which one should I hook it too? Like I said wanting max performance with NO engine damage.Also I run 93 octane in the car all the time.
