Holley adjustable jet kits
I see that there is an adjustable jet kit available from Holley for my 4150.
Seems like it would be the hot setup for dyno tuning or A/F mixture settings.
Are there any downsides to using it? If not, why don't the carbs come with them?

I think it is added between the metering block and the carb body adding length to the carb by moving the float bowls out. This causes a problem with the dropped base air cleaners.
Also I found I ran jets around 80 and you had to buy a range of adjustment and with my setup the range was right in the middle of the two ranges.
