"Add jet until it slows down and go back down a size.

Does your 3310 have a secondary metering block? If not convert it.

If you add one step in jets and it slows down, go the other way until it slows down. "


Thanks for the tips Cudadog, i do have a secondary metering block. When you say "add jet" should i just focus on the primary side first? Or try primary and seconary at the same time ?
I'll definetly be buying a log book,Holley jet kit and weather station before my next trip to the track.Maybe i'll try 40 psi in the fronts next time. Do you think 38° total is too much timing for a 9.8-1cr with iron heads on 91 octane ?
Thanks for all the solid info guys 👍👍
