Could someone tell me what the injector on the left goes to? I bought them from a guy who said they went to a 502 mag and had them flowed and checked. I've got over $300 in them and they're not the same as the ones in my 502. I guess they're for sell if anyone needs them. Thanks.

The one on the left looks like part # 861260T, for all 454 and 502 MPI models 1999 and up, with MEFI3 and Cool-Fuel.

The one on the right looks like part # 805225A1, for all 454 and 502 MPI models, 1993 to 1998, with MEFI1 and Vapor Seperator tank (VST).

Ken,if you have your fuel rail off motor the earlier mpi rails (from what I understand the ones that use the bigger injectors) have a tiny hole feeding # 7 or 8 injector,check this as it may become a restriction on your blower motor and lean out the cylinder it feeds. You could drill it out at home if your careful not to damage the bore where injector seals to rail,Smitty

Hi guys, sorry to bring up an old thread, but do you guys know what the factory injectors flow in a 502 mag efi? 98 VS 99. I'm guessing they are around 36 or 38 lb/hr but I don't know for sure.

Thanks,

I have a cleaned, flowed set of 42# injectors for sale in the swap section $ 200.00. Came off my 502 intake. I will gaurantee them to work in a 502 intake. They are excellent for a stock, hopped up 502 or a Procharger set up.

They are Lucas Injectors
