351W Intake Manifolds

[nitroracer]

I have a question for those of you running 351 windsors in your cars - what intake manifolds are you using?

I recently picked up a 351HO from an 87' bronco and I want to replace the stock 4bbl intake before I transplant the engine into my 87' mercury grand marquis. Since the car is on the heavy side I want something with a good powerband from idle or 1000rpm on up. There are always a ton of deals on eBay for older edelbrock performer manifolds but I can't find much information on them. Another choice is the weiand stealth which I am leaning towards but much harder to find. I am looking for something I can pickup used without paying an arm and a leg.

If you really want a powerband \torque starting anywhere from idle to 1,000 rpm; please stick with the stocker or an old Performer. Clean it up & gasket match it if you like for a little more mid-range "ooompf".......IMHO

I have a Performer RPM on my 351W and it works really well IMO! Great low end torque, and it works well right up through the RPM range up to 6000.

stock-mild cam w/ stock heads use a low rise intack. mild cam and performance heads use a high rise 180*. performance cam and heads use a hight rise 360*

what di you mean 180* and 360*? for my 351w build i plan on a victor jr. intake, if it clears the pace car scoop, i would also like to use the stock duel snorkel air cleaner but i know its a long shot

I guess I should add a little more to what I am looking for...

I have a pair of GT40 heads to run on the engine and I want to find a mild street/strip cam - the car isn't going to be a daily driver but I want to cruise around in it from time to time. I figure idle/1000rpm on up would be best for such a heavy car without requiring some major gearing to get any off the line acceleration, I have 3.27s now but may upgrade to 3.55s.

doesn't that car have EFI ? why not convert it to mass ? with a truck lower , and 302 upper , he should be good .

Good luck with that. I have a vic jr and it's a pretty tall intake.

I have a older styler performer and a 600 Edelbrock carb, I'd like to go to a different intake when I redo the engine but was told this one is a good intake. The newer ones have smaller runners than the older style.

I had a Pro Products typhoon but wouldn't fit under the hood w/o going to a drop mount.

Dual plane Performer RPM or Air Gap will work fine. The Air Gap has longer runners for a little extra torque. The "air gap" part is a bunch of silliness but it is a good intake.

180* is splits into in 2 plart where 4cyls will see on side of the intake and the remaining 4cyls will see the other side. 360* is an open plenum.

A victor jr will not clear and is only useful above a minimum 3500 rpm (more like 5500rpm-7800rpm). I have a vic Jr and drop mounts and it sits about 3" above the hood with the proper sized air cleaner. Use a 180* (performer, performer RPM). Loose the snorkel it only good for at best a mild 302

[nitroracer]

It is currently an EFI car but I want to build a carbed engine for it. Truck lower and car upper don't bolt together without an adapter and still doesnt fit under the hood. Then comes the problem of finding a computer to run it, because there isn't one. Carbed will be fine for this car because its not going to be daily driven.


And it looks like a plain old performer will fit the bill. Thanks guys.

i have the TFS george forman grille
its awesome, best one on the market. but i had to mill it to make it fit under a 2.5" cowl hood, even with drop solid motor mounts

I have a 68 Mustang Fastback with a 351W, I put a Edelbrock Air Gap intake on it, made a huge difference, I am vert happy with it. The intake is tall so you may need to modify the hood.

You dont really need to worry about "hurting torque" with a too big of an intake when swapping a windsor into a 302's spot. The windsor will have more torque than the 302 reguardless of the intake manifold.

For whats concerning you, a weiand stealth or an Elelbrock performer RPM sounds about what you're after. Just be prepared to install a hood scoop or cowl hood to fit it. With a windsor its very tough to install one in a fox body without hood clearance issues.
