Hey I was wondering if anyone knew the part # on the holley 670 cfm throttle body that fits our cars. I am looking to buy one used soon and I just want to make sure I get the right part number. Thanks for the help.

 

You want the Holley 502-6

 

keep in mind you will need a custom chip as well. Even with the 502-5 (57pph injectors as opposed to the 502-6's 65pph injectors) I ran way rich until I had some prom work done.

 

I have a chip out of a cop car caprice , will that chip work with it?

 

I'm not sure. Cop cars came with 65pph injectors, so it should be pretty close. Just keep in mind the holley injectors are rated at 21psi.

 

hey r90camarors, what is the pn number on the top of your injectors. I have the delpi units and i suspect that theyre the 65 pph ones but i cant be sure. You have the 57 pph's so that would help me figure it out by process of elimination. Either their 65's or 57's and im still not sure which. I see they also use colored filter screens which may be a way to id them but i emailed delphi and got nowhere with them.

 

I've got the old 57pphs in storage, I should be able to check it out today. I can't remember what color the screens were, but I'll check. I know purple for sure, but I can't remember off hand if that was on the 57s or 85s

 

Sorry it took so long to get back to ya-the storage unit was a mess. Anyways, the part number to the 57pph delphi injector reads like this: 6191^5284 The screen is purple as well, though I think they're purple on my 85pph injectors as well-so i'm guessing they're not color coded. Hope this helps.

 

the pn on mine is 6201 5389 so im assuming that their probably the 65 pph's Thanx for the PN.
