Plates are fine,

Front plate #34
Idle feed .036
Main jet .089-.089

Rear plate #35
Idle feed .036
Main jet .086 right .093 left

Kill bleeds .043

Idle air bleeds .055

High speed bleed.038

Throttle blade hole.078

This is what I found on 3 stock 1970 440 setups, 69s are not the same, 340 is not the same The mopar performance #34, #35 plates match this, some later plates did not match for me, had smaller jets. If this is wrong hopefully someone will correct.

Some have said their promax plates had bigger idle feeds so check to be sure. Match a stock 34 and 35 plate to start.
