I swapping a c4 for a rebuilt c6 in my 70 torino. Anyways, my big question is this... I have a Holley 650 DP that is not normally recommended for ford's unless you install a lokar or similar kickdown kit. I want to keep the 650 DP due to the fact of running NOS and a better overall carb.

So, do I keep the 650 DP and install the kickdown (how difficult is the install?), or do I go back to Summit and excahnge for the cheaper 750 due to having the kickdown installed?

Please advise, I probably already answered my own question, but need some direction since my motor is due back from the machiners tomorrow.
