289 Hi Po Manifolds anyone?

[Eos]

Does anyone have these on their II? I thought it might be an easier alternative to headers. I have read a bit about them in mustang magazines. It says they bolt on just like stock manifolds on any 302. Comments?

I haven't tried myself, but others say they won't fit on the II.

Get headers.. it will make that trip youve been planing to PA more fun

any 'cept yours

Why wouldnt they fit on a II? I thought manifolds set close to the engine, they are out further then headman headers are or what?

The II manifolds are very specific to the II. The left (passenger side) is flat and drops differently than other 302 manifolds. The right side is more traditional. To have your II manifolds flowed is like 300.00 bucks OUCH! Headers, just think headers.

I went out and looked at my manifolds, they looked identical to each other, but I did notice more clearance on the right side. My engine does set a little higher due to the motor mounts, a good 1 to 2 inches. I don't know if that would make a difference. Anyway, I hate ford for the retarded non swappable things they did to the II.

Don't blame Ford, blame Lee Iacocca and his clueless group of engineers. Ford, for many years, has always been really good about retrofitting similiar drivetrains into alike chassis.

Never tried the Hi-po manifolds. Don't see any reason offhand why they wouldn't work. Unless the starter re-positioning causes a problem. I think it's just having to shell out $300 for cast iron that still underflows the cheaper headders, that kills the deal. It'd be a good idea to research.

Another II hater Come on megan resist the urge

Megan, here is my advice.. if you have the Hi-po headers laying around then try them. If you don't then look on e-bay for the Hooker headers. A few months ago you could buy a set on there cheap, like around $100-150. I'm not sure why.. it just seemed everybody wanted to get rid of them?? Anyway I still see them popping up from time to time. The Hooker headers are easily installed with the engine still in the car... why? Because the passenger side comes in two pieces.. one that slides in from the bottom and one from the top. It is an easy weekend job. Of course you'll have to get a muffler shop to weld on the collectors so you can bolt up to your existing exhaust once you're done.

I heard the hooker headers wouldnt work on my II because I had a 5 speed transmission. So I thought I had to go with hedmans that are 120 bucks.

 

[JonDawg]

IIRC, the HiPo manifolds drop down straight under the third and 7th cylinders (no??) If so, it puts the exhaust exit straight into the steering joint, and the starter. Thats why they wont work.

I havent gotten around to getting headers, but the stock manifolds are by far the easiest.

BTW, anyone have any idea how to make a set of shorties???

 

[Stang2Man]

dmoody I think you may have hookers and hedmans confused, I know hedman headers are a two piece I got em on my Cobra, and I'm pretty sure it's hooker/dynomax/blackjack (same thing) on my brothers Ghia, The Hedman's are alot easier to install, and the other one piece designs are a little rough, you can never get the car far enough in the air, and then you have to lift the motor, very fun. But you don't have to weld up the the two piece headers mine never leaked in mine until I started playing around with them (scraped em up real bad and tried to replace the pipe) but I think a header wrap would work well on it, never got around to tryin it.

Don't blame the engineers. They were told to design the Mustang II as a small car that would accomodate a 4 or 6 cylinder motor. Then after the car hit the market Ford realized buyers still wanted a V8. So Ford had their engineers stuff a 302 where it was never designed to fit. That's why we have II-specific parts like oil pans, motor mounts, and exhaust manifolds.

It's a good thing they used a standard 302 cause internal parts on the 302 are very interchangable except for the the timing cover, balancer, flex plate

I've got Hookers and the passenger side is actually 3-pieces.

 

[dmoody]

You're right jeffnoel, I forgot that the two forward pipes are actually separated. The passenger side is three pieces. Megan, I've got a T-5 in my car too and I didn't have any problem putting on my headers... I didn't have to jack the engine at all. The only mods necessary are in reattaching your existing exhaust system to the new headers.

And you have hookers?

And you have hookers?

lol Isn't that a little personal?? lol sorry I couldn't resist...

man I just gave you a CT and now you are beggin for a new one
