Jetting question

[shagmebabe]

Just added an Performer Manifold in replacment of the stock iron. In reading the Holley stuff it indicated that I may need to jet up with a perfromance manifold.... Is that right ?

[centerhill condor]

this is why I leave it alone...jetting can go on for quite a while! You may want to adjust your jets during the weather you boat in most frequently.

O.k. should I just do so speed runs and shut her down and do a plug check ? is that the correct way ?

[SmokinLowriderSS]

Yes, that is right.
I did not have to change mine from a chevy iron Dual-plane, your results could be different.

Every application is different just have to try it, plugs will tell!..
