Carbs and HP

He's probably running it with annular boosters too, that makes a big difference for a big carb on a small engine.

 

Yep, annulars. And a dual plane intake so each cylinder only "sees" half the carb.

 

A 4118-S is a 725cfm carb. Should be a dual feed ,heated choke, single pumper
The R-4118 is holley's universal replacement same cfm choke. May vary

Oe application for a 4118-s for a 68 hi-po 289 that being said I would run it it being a vac-secondary it won't let anymore air then needed through the secondary venturies.
If ford and shelby thought enough to run it on a 289 why be scared to run it on a 302


If you don't run it I might be interested in buying it

 

Run the 725. Toss the Edelbrock into the street and watch it get run over. Open beer.....smile.
