Stock 351w 4bbl intake

[GilroyRacing]

Wich stock 351w intake is better? I know none of them are as good as aftermarket, but as far as stock intakes go wich is the one to get?

1969.

After that, it's a bit difficult finding a good one, as there weren't too many stock 351W's with 4V's in the 1970's....if any....and the 1980's 351W 4V intakes have EGR issues to deal with.

How does the 69 intake flow compared to the 80's truck 351W 4V H.O. intakes?

You can get a used aftermarket just as cheap. I only paid 100 bucks for a polished edelbrock 4bbl intake on ebay.

The earlier, the better. If you go 1969, you will have those four extra holt holes (I wouldn't leave them open - can't if you'll have any water jacket issues or not) unless you are using 1969 351W heads (in which case it'll be a perfect fit).

How does the 80s 351 HO intakes flow compared to the 69 intake?

Not sure anyone has really put those on a flow bench. Usually the first thing people do when trying to get more out of a motor is put the stock intake in the trash. I'd say get whats available and port it. I'm guessing you have some special need for an OEM intake manifold?

What I remember reading on jason.fletcher.net before it went AWOL (permanently "under construction", from what I can tell) is that the original '69 low-rise intakes and 4V EGR intakes from the '80s generally performed about the same - or at least, they would if they follow the same trend as 302 manifolds. The site owner had posted flow numbers for a variety of factory intakes, and the way I remember it, the '83-'85 Rustang intakes actually flowed slightly better than the vintage factory low-rise stuff. Still no good at much over 4500rpm, but a great low-RPM street intake.

+1 on why you must have a factory intake, with Performer 2181s so readily available for cheap.

Wich stock 351w intake is better?

1969-1970 Shelby GT350 aluminum intake was the best. Neither the 1969 iron intake nor the 1980s aluminum truck intake flow worth a crap. As it was mentioned, the factory intakes are harder to find and often no less costly than the plentiful used aftermarket offerings.

Didn't the GT350 get a 289? I remember reading that the Edelbrock F4B was basically identical to the C9OX, etc. (Ford and Shelby versions) and that nowadays you'd normally buy a PN 7121 "Performer RPM" fro your 289 or 302 unless you had to have the correct vintage look.

65-67 GT-350's used the 289, then switched to a 302 in 68' and went to the new 351w for the 69 (and 70) model year.

But as with the 289-optioned Shelbys....the Paxton option was available all the way until 1970 (I have an article on a '69 GT350 with one), even on a 351W.

Oh, so they did indeed actually produce a F4B-style intake for the 351?
