Holley 94 jets
The Holley 94 8RT truck carb I just took apart had 52 jets in it. I have read on here that 51 jets are recommending and that is what I have in it now. Would I see a performance increase with 52 jets? It’s an 8BA bored 60 over with a 4” stroke.

Re: Holley 94 jets
You are looking for the best A/F ratio for the application. An A/F meter helps a lot. The idea jetting can vary based on all kind of factors.

I added an A/F meter to my test stand and found it quite valuable.
I have yet to put one on a car, and may never do so. |

Re: Holley 94 jets
The 94 type carbs came with some different sized jets over the years from '39 to '56.
Some had 52 jets. I would just leave it alone and see how it runs. Sal |

Re: Holley 94 jets
I would choose 51 jets, but you shouldn't have a problem with 52's.
