massive reconfiguration time again.
That' funny cuz I would have NO IDEA how or where to start tuning those carbs....
Holley carb=easy to tune.
Set the transfer slot, 1 1/2 out on the idle screws, then use the main jet recommnded by Holley and most times it' done.
If you wanna go deep you can but they are a set it and forget deal..
But free is always better!
