Hey everyone!

I have a '66 Galaxie 500 w/a 289; my cam is as follows:
Lift: .448"/.472"
Adv. Duration: 262/272
My car is a cruiser, I'm going to be running duals from factory manifolds & I have no plans to do any kind of racing, but I also want to get as much power out of what I have; so which one do I want to go with?

Mr. P-Body 03-02-2013 09:53 AM

Which one "what"? Please provide as much information as possible, including what your goals are.

x pipe.. and a good set of points that not bounce.. and send the tach to the moon..

alberatzi 03-02-2013 11:24 AM

Sorry about that! X or H pipe for my dual exaust.

alberatzi 03-02-2013 11:48 AM

I hate points, that's why I have an HEI distributor.

wont make much difference on a stock engine
adding an"H" pipe is cheaper,makes it quieter and sounds better

alberatzi 03-02-2013 12:30 PM

Well, my engine's not stock. Pistons are +.030, crank is -.010, Jegs cam & lifters~ Lift: .448"/.472" Adv. Duration: 262/272, Comp pushrods, Comp Magnum roller tip rocker arms, Pertronix HEI distributor, MSD Helicore Wires, Edelbrock Performer intake, Edelbrock 600 CFM 4 bbl (stock intake was cast iron w/ 2 bbl), Autolite Platinum plugs with a 3" K&N air filter to top it all off. Keep in mind this car weighs around 4800 lbs. & it's a cruiser, not a bruiser.

On one hand you are saying its just a cruiser and then you want as much power as possible.......:confused:

Face the facts...its a big car. That little 289 is overworked.....If you want to go fast, you are going to need more cubes....maybe a big block

or, just be happy with what you have

The amount of difference in power gain from an X pipe as opposed to an H pipe is negligible , unless you are up in the 5-600 horse range. Then the X might net 7-10 h orses.
Run the H. They are far cheaper, I have the Flowmaster H pipe mandrel bent system on my ride. It was like 360 bucks from summit. Worked out nice.
I would order it without mufflers if I did it again as the flowmasters are a bit droney at a certain RPM. I think the magnaflows are a better the 40 series.Or even the 40 series deltas.:thumbup:
My buddy was standing around when I drove by and he said it sounded real good with the flowmasters on it. And it sounds good at an idle and when revving in the shop, just wanted to mention the flow masters do have a little drone at certain RPMs and may or may not on your car.

I wouldn't bother with either. I don't think you'll see much difference with that heavy car. More cubes would help more than anything.

455olds 03-02-2013 05:54 PM

That is a very heavy car for such a small engine. My 3/4 ton truck can't weigh much if any more than that car.
Turbo or supercharge it if you want it to get out of its own way.

I appreciate all the advice & constructive criticism. I want to balance the exhaust pulses from both banks so I don't get those annoying popping sounds from my exhaust, which is why I asked the question in the first place. Again- thank you all so much for everything! :cool:

Just run duals with glass packs in the middle & resonators on the ends! Like in the 60s the 289 with the dual grind cam would sound nostalgic look for a dual quad intake at swap meets or even new at speedway!!! Cruisers aren't supposed to be fast just look cool :thumbup:


bigdog7373 03-03-2013 04:02 PM

Not much difference between the two performance wise. The h-pipe will give the classic muscle car noise, the x-pipe will give it a more modern v8 sound. It's mostly about what will fit the car and you budget, plus what sound you prefer.
Ever consider a dual in/dual out muffler? I had one and the sound was amazing. Really smooth yet muscly sound. I really liked it. I don't know how it would affect performance vs a dual muffler system though. I do believe that some sort of crossover, whether it be h or x pipe, or a dual in/out muffler will yeil better performance than a dual unbalanced system.

Nothing wrong with trying to maximize your potential. I'd go with the H-pipe and a low restriction muffler
If you dont want 'popping', don't run glasspacks on true duals without a resonator.

If you install a balance pipe; you may want to think about not welding it in solid. I helped a friend R&R his 700r4 and we had to sawzall his homemade exhaust system...He was kinda grumpy about it.
