351 windsor intake manifold question

When I bought my car someone had clear coated the intake manifold. Now it is yellow and chipping off. I was gonna pull it off and sand blast it, but I am wondering if I should just buy a new manifold. It has a Edelbrock Victor JR on it. Here is what I do not understand (be nice)....According to the Victor Jr specs, the max HP range is from 3500-8500rpm. I like low end power and torque, even when I normal shift, I am under 3500 rpm. 3500-8500 seems kind of high. Can someone explain this to me? I was looking at the Edelbrock RPM Air Gap manifold. They say the power range is 1500-6000rpm. Am I wasting my money changing manifolds? Should I just clean up the Victor Jr?

Re: 351 windsor intake manifold question

the Why . that the only mod along with a 4V carb ?
no other mod's then iis big the better thinking .

that's the only mod , then a performer would be a better manifold for your rpm range

Dart heads, pretty lopy cam, mechanical and electric fuel pump with regulator, Ford Motorsports distributor with mechanical advance, MSD 6al. Definitely not a stock engine. If I was gonna run the car at the track I could see having something in that RPM range, but I do not plan on doing that. Thats about all I know about the engine

I'd get a Performer RPM (non air gap) . that would be a good compromise , not given up much on either end

So this will improve performance/acceleration in my driving range? Or it will be about the same as my existing manifold?

Re: 351 windsor intake manifold question

your driving range , a stock 2 barrel intake and carb will be fine . rpm intake will not give up much in that range

The Victor JR is for high RPM track/hot street. It offers very little low end torque.

The PERFORMER RPM will give you much better street manners. Talk with EDLEBROCK TECH.

Re: 351 windsor intake manifold question

Ford 260-289-302 V8

VICTOR JR. 302 (3500-8000 rpm)
Designed for Ford 289/302 competition engines using modified stock cast iron or aftermarket Windsor-style cylinder heads such as Edelbrock heads #60259, #77169 and #77219 or equivalent. The Victor Jr. #2921 has no rear water crossover. Port exit size at cylinder head is 1.90" x 1.08" with enough extra material to open it up to 2.10" x 1.18".
ApplicationsPart #
Victor Jr. 302 (non-EGR)#2921*

Carburetor Recommendations: Use appropriate racing carburetor.

$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$$

That is one big intake for the street. Single plane. Hopefully the PERFORMER PLUS will make it more street-able.

It must be a bear to cruise in...



You know... Someone built that engine for serious usage. You might have to go in and calm the cam and compression down to make it a driver.

The new intake, whether RPM or Air Gap (Dual Plane) might just choke it down to aggravate you as the valve-train is most likely setup for serious usage.

Make sure you talk with a TECH so you can't blame me...

Re: 351 windsor intake manifold question

Pretty good article here explaining single plane and dual plane intakes.
Performance Intake Manifolds

You can have the best of both worlds. Looks like my biggest issue is the single plane intake. Explains why my car always hesitates off throttle unless you really tromp it.
