1967 Shelby Gt350 Help

Hi to a new addition! The parts you are looking for are not difficult to locate,much of it depends on the level of correct that you are trying to attain:some of us look for date coded parts-others just want to function and drive.The exhaust is a great example.They are available as a decent copy with an aluminized coating in both small and big block sizes.And now are available in stainless steel as well.They are also available as an exact reproduction but prices vary accordingly.From a performance stand point larger diameter will yield more power.Original dual resinator-single transverse muffler type are easily replaced with the 1970 dual muffler type systems,and are available in several aftermarket forms from several companies.Just make sure if any modifications are necessary,that you don't cut up the cars floor pan,Do you have the correct clutch and brake pedal setup? The 1997 registry lists 2221 as a 4 speed lime gold car sold new in Ohio..did someone convert it to an automatic in the past?if so the pedals and linkage will also need to be reinstalled,and a correct z bar (they are unique to a k code if you are running stock exhaust manifolds)Please let us know more
P.D.

 

Try doing a search for David Key Toploaders. Dave should be able to help you find the pieces you need. Jack at Deadnutson can do a awesome driveshaft.

 

Since you are in the discovery process, if you are not doing a Concours correct resto, you might want to consider putting in a Tremec 5 speed. That to will require a custom fit drive shaft.

And as already answered, the original exhaust was 2" and a transverse muffler.

 

Second the motion on the T5. I pulled the original close-ratio 4-speed out of my 67 GT350 and put a T5 into it.

The close ratio tranny isn't a good tranny behind a street small block IMO. Takes too much clutch slipping to launch the car in its power band. It's OK with the factory 3.89 gears but then you are turning 3500 rpm at 70 mph.

5-speed lets you have your cake and eat it too. I have 3.89 rear gears with a 2.95 first gear so the car gets going in a hurry. Plus it only turns 2300 rpm at 70.

 

Good points from all - what it comes down to is what level / type of "restoration" do you want to attempt, and how do you intend to use the car?

Good luck, and Welcome!

I removed my original exhaust system about 8 years ago and stored it all away, and installed, and love the dual Flowmaster system for performance and the sound it makes, the sweet spot is 2500rpm. I would also highly suggest the T5 or T500 Tremec swap, you can purchase an original style shifter so it looks ok in the passenger compartment. The conversion kits that are sold make the job very easy to do, and you'll love the OD gear.

 

Hi again to Bob and all! the research that I have done shows that a 67 289 4 speed is a wide ratio with a Ford tag of RUG E1 . If so it has a 2.78 1st gear ratio.A close ratio would be coded RUG AG and have a 2.32 1st gear ratio.To answer your questions,it is simply put, a lower 1st gear ratio will launch the car better,and the overdrive will save you fuel on the highway which is why several people have suggested the 5 speed.If the car still has 3.89 gears in the rear axle then it will not be a slug off the line,but the 5 speed will wake it up nicely.You will feel the difference.The even bigger benefit is the lower RPM while crusing in fifth gear on the highway it is easier on the engine and helps save MPG.It is now a bolt in swap,but will cost more. As values go, most people that collect rare cars look for originality however the auction craze over the last few years has shown that trend changeing and resto-modified cars have sold for crazy $$$ The choice here should be on how the car will be driven,and what you really intend on doing with it.With any car they are worth much more running and functional so let us get you there first.Do you still have the original exhaust manifolds and H pipe ? What about clutch and pressure plate,and shifter? Can you post pictures?

 

Hi Bob,

First off, congratulations on the Shelby!!! I'm very envious. Regarding the transmission choices, do what makes you get maximum enjoyment from the car. If you want to drive it a lot on the freeway, go with the 5 speed. If the thought of a 5 speed in a '67 GT350 makes you feel like it's been violated, then don't do it. Either way, a hipo small block with a 3.89 rear is not going to be a dog off the line.

I have 2 Mustangs (not Shelby's ). One has a t-5 five speed and a 9" rear with 3.89 gears. It goes like a scalded cat down low and keeps the RPM's low at freeway speed. My other car is torn down currently, but I have a wide ratio toploader to put in it because my vision for that car is to keep it as a period correct-ish track car. I guess my point is, I completely understand you not wanting to stick a 5 speed in it. It all depends on your vision of the car.

If it were me, I'd probably collect all the correct parts and linkage (including the toploader) and stick them on a shelf and run a 5 speed in it. That way, I'd get the benefit of the 5 speed without feeling like I'd violated the car's heritage.

Congratulations again!
Josh

 

One of the best things I have done on my 66 was put a 5 spd in it. Congratulations on your new toy. I used to own 2220. It was a lime gold 4 spd car too.

I would keep it with the 4 spd and the factory 3:89 rear. I have two original '67 GT350's with this combo and still fun cars to drive. The 5 speed is nice if your doing a resto-mod,[infact I did this conversion to a '67 Jerry Titus clone TA coupe,worked out great], but you own an original shelby, its not original to the car and would effect the cars value. History has clearly shown that the more correct and original the car is the more its worth. JMO [It would be like cutting a hole on the roof of a daytona coupe to put in a sun roof,....just couldn't do it].

 

If it were me, I'd probably collect all the correct parts and linkage (including the toploader) and stick them on a shelf and run a 5 speed in it. That way, I'd get the benefit of the 5 speed without feeling like I'd violated the car's heritage.

Congratulations again!
Josh

i agree with Josh....you have the opportunity to have the best of both worlds..... if you're going to get it out of the shed and blow the cobwebs off every now and then....run with the T5 (who's ever going to know but you) but keep the original bits to put back in if you ever decide to sell.....
cheers mate

 

I have 67 GT350 #2355 currently with the rebuilt original 4 speed Toploader and 3.89 gears. I was investigating overdrive alternatives and heard the Tremec 5 speed requires extensive modification to the floorpan. The Keisler Engineering 5 speed, as per the company, only requires a dollar size piece of hump be modified. I am now looking at the Gear Vendors attachment that gives midrange gears between all original ratios plus a 5th overdrive gear. It attaches to the tail end of the original Toploader and requires a new, shorter, driveshaft. Any input on these three options would be appreciated.

I also started a new thread with this same info.

 

I'm pretty sure all 67 GT 350 4 speeds were of the close ratio version. I know mine is, and it doesn't really launch in first that well. I've heard other's comment the same thing. Also is a 3:89 gear rear.

Hi,
Just curious about the trans tag number on your 4 speed.Randy might have a valid point,and a tag number would help provide info.
Currently have a friend doing a 5 speed conversion on a 68 and it involved a few modifications to the engine mounts and the tunnel opening--not what you would/should be doing to an original uncut car right?
Please keep us posted !
P.D.

 

Anthony,
The tag number on the trans. is HEX-BX
