Holley 770 on a 496 - Change Jets?

1150 Views 1 Reply 2 Participants Last post by  BACK FROM THE DEAD

My 496 build is moving along, and the plan is just to use the Holley 770 Street Avenger I have on my 396. 100% street motor.

The plan is to use the 770 on the initial fire-up, and run it to see how it goes from there. The carb has been trouble free since day 1 and has not had any changes made to it except the spring for the vacuum secondaries.

Will this carb need to be re-jetted, or should this be a wait & see approach?
