If you are going to do 4500 series carb let me get you an ADP billet 1050 and all of the mystery will be gone.

Hey lem how much are those intakes and do you have 1 in stock thx ?

ADP billet 1050 is a carb not an intake. Availability is not an issue

Oh why not a dominator ? 4150 better?

4500 series is a 'dominator'.

Must misunderstand sorry the dominator is a 4500 but you said to go with a adp 4150 so I presume you say it is better for this application? Thx

"If you are going to do 4500 series carb let me get you an ADP billet 1050 and all of the mystery will be gone." This is what I said.

Sorry I totally misunderstood

Lem said APD 1050. Sometimes we see other numbers and I recall seeing 4150 as well. I just looked up that APD 1050 and its features are that its all billet construction and its type 3 anodized. I like Dominators over 4150's mainly for the big venturi's and annular boosters. They seem to be quicker in transition and atomize fuel better over 4150's.

4700 More better. New Improved.
