Sorry if thismay be a beated subject but, I'm thinking about pulling out the 2V carb/intake on my 289 and throwing on either my 302 OEM 4v intake/carb or going with Edelbrock's Performer intake/carb setup. Performance wise, are they going to be about the same? If I recall right, the difference between HP with a 302 2v vs 4v was about 10HP. Would the Edelbrock setup be a bit more?

With the OEM carb, I think I would have to rebuild it (there some cobwebs inside of it[:-]). Is that a task not for the unexperienced?

The 289 is pretty much stock except the PO told me he put a "warmer" cam in there when it was rebuilt.

Thanks

 

why put another heavy steel intake on?
go with the aluminum one.

 

Definitely go with an aluminum manifold. Unless you're restoring for show points, I don't see any reason to ever put a cast iron manifold back on an engine. The weight savings alone are worth it, IMO.

Either the Edelbrock Performer Plus or the Weiand 8124 will work well as a stock upgrade. The Weiand is a newer, slightly better design, but if you run across an Edelbrock for cheap I wouldn't pass it up. It is NOT simply an aluminum version of the factory cast iron manifold, as some people seem to believe.

With a good manifold and a properly tuned ~500CFM carb, I'd expect about a 10hp increase. The real benefit will be in throttle response and top end pull.

 

Go with the edelbrock. It will be a little more power but more importantly, more user friendly.

 

Anyway you are not really taking advantage of the 'warmer' cam without a better flowing intake.
