New jets needed?

As far as the trans. you have to make sure your kickdown rod is all the way back at wide open throttle. Should be very little movement. Just enough to not bind the linkage at WOT. Also not sure how parallel your linkage is. Should run parallel frt. to back with the valve covers. Summit and Holley carbs are more narrow then Eddy/Carter types and sometimes require this adapter..........

Here's a short vid showing too much rearward play in the kickdown rod.....
