I pulled this off a 1984 351W 4V H0 truck motor.
E4TEARA
A4F15
It is a Motorcraft mfg by Holley. It has 4 corner idle adjustment.

Can some tell me what the Holley equivalent is if there is one. What cfm it is.
I may be needing a rebuild kit for it.
Or should I just ask Holley?

Thank you very much

If it's the original carb for that engine, it should be a Holley 4180. Also used on the 5.0 HO 83-85. 460's also got them. 600 cfm similar to the 4160 but modified for better economy and emissions. Most noticable differences are "tamper proof" mixture screws and annular discharge boosters on the primary.

Thanks, QnD.

BTW, non of the mixtures screws are capped like usual. They could have been tampered with.
