Holley Help Needed

OK I'm back from a blast around the streets I increased my timing to 15* & installed a set of 72 jets in the 600 vac holley.

results are it binged a little but the acceloration did improve it seem to rev quite happy to just over 5000rpm but feels like a 750 vac would really wake up the old girl & it moving.

I will endevor to get hold of a 750 vac & change to the Edlebrock performer dual plan & see what happens.

Stay tuned

Cheers Graham.
