I have a 4320 I am thinking about getting invoulved in pulling. here is what i am thinking about doing. I want to run 466 cubic inch, flowed 4320 head w/6030 vavles. stock injection pump w/ little modifications. get my injectors lasered out . big lines. I am also wanting to run a 3 LM turbo. I am also thinking about running a high performance cam. So If you can please tell me what i would end up with hp wise. Thanks

I would guess that you are thinking of using the 466 block. This would give you the P or A pump.. I would start with the P pump if you have a choice.. like others have stated check the rules where U are going to pull.. If you have to run the rotary pump you will be more limited, but you can get some power out of them. If you want to start with a stock pump look for a pump and injectors out of a 8440. But most of the P pumps can be modified to get what you what. (The cubic dollar theory.) I have ran stock 466's on the dyno at just over 300hp, and the screw on the pump still had a ways to go. (4640) The other thing is are you limited to RPM's, some of those pullers run at some Nasty rpms, and made lots of HP.. Well.. good luck with the 4320... JDGnut

Stock pump ? are talking about the 4320 Rorary pump or an inline Bosch from the 466 , makes lots of difference . The rotary with .450 head limits you somewhere about 350 - 375hp maybe little more depending on rpm's with the inline Bosch A or P pump there is a lot more available , depending on $$$$$$$ . You have to watch the rules for where you want to pull , some groups have pump rules , JIM
