NOS Big Shot plate

I have an NOS Big Shot plate. I have been able to find a jet size chart that lists the jets and the accompaning horsepower, but it starts at 225 and goes to 350+

Here is the jet size from the website.

Nitrous/Fuel jetting.





Heres the problem...when I got the kit nearly all of the jets are machined wrong, and they dont physically fit into the jet tubes.

I found only two of them that do. They are 73/82 but Im not sure of what these jets equate to in horsepower.
A few have told me that its around a 150 horsepower hit, but I cant confirm it.
When I called the NOS techline and asked them about it, the guy was real snotty with his attitude and then told me he could not give out that info.

I dont know why the hell not, but regardless, perhaps a few of our excellent 460 Ford members can tell me!!


As the world turns...I get more dizzy!

Are you sure the "73" isn't a 93 ?? sometimes it is really difficult to see the # good.
otherwise I would put it in the 150-200 range. try it and see!

I bought a nos big shot plate years ago, and I still have the jet card.
mine says
100hp= .047N/.053F
175hp= .073N/.082F

the rest of the jetting is the same as you have listed. although when I bought mine they had told me that at the lower levels it does not have as good as distribution as compared to the 225 setting or bigger.
hope this helps
