- 72 Mustang Grande / 351 Clev. 2V + Weiand XCelerator intake + Holley 600 CFM carb
I'm thinking about changing my carb. It's an Holley 1850 (vacuum secondaries) which flows 600 CFM. It's old, shows signs of wear, has no choke and I think it's the next part I'll be changing, it looks like old technology but I'm not sure.
But I don't know which new or rebuilt carb will work best for my motor and using.
Motor is a stock 72 351C-2V. Intake is an aluminium Weiand Xcelerator (single plane). I have long tube headers and dual exhaust. I think I'm somewhere around 250-280 HP.
My Mustang is not a daily driver, just a weekend cruising car, but I want it to provide some fun by pulling a few HP and good torque.
I have the C4 trans right now but I'll swap for top loader in a few months.
My Mustang runs good, especially above 3000 RPM... Maybe a bit loosy under 2500-3000 RPM (because of single plane intake ?).
I'm a bit confused because i dunno what to choose. 650 Speed Demon carbs look amazing but will it run good on my Mustang ? Motorcraft 4300 is always an option (better mileage @ low RPM), Holley spread bore is another one. And I don't know Edelbrock at all...
Mechanical secondaries would be great, I'm not a big fan of vacuum carbs.
Please can you help ?
I'd like to keep the Weiand intake if possible (I can use a spacer if needed) except if you think this ain't a good idea
Thanks !
