More HP on 273 Stock 63 Dart GT Vert?

[cudamark]

Thanks, Mark . . . here is what I have got from your advice . . .

1. I will go with the simple cam solution . . . no notching! Not my gift set.

2. The 65 4bbl carb would be best . . . but since it is a summer project and short time to find, I may have to compromise and go with aftermarket . . . 600cff or less with a little jetting . . . . then, knowing the air cleaner may be an issue.

3. Remember that the factory 4bbl kickdown linkage or an aftermarket cable setup

4. I will look for pre-notched exhaust and definitely want to do the x-pipe.

5. Plan for this to turn into a four day a week commuter into Atlanta a couple of days a week in good weather . . . that means 15 miles on 2 lane country twisties then 15 on an 8 lane interstate to get to work (and of course back again). So, a mid gearing solution best for me. Keeping the 4 speed manual in it . . . so 3.55 seems the best compromise?

6. No low profile look for me, but those 13 inch tires, wheels, and hubcaps will have to go in storage. Going to go with the 8 3/4 rear end . . . desire the tallest, widest tires and wheels I can. I will just have to measure after the rear end goes in and order from there . . . like tall and wide as possible, but with no rubbing!

Since there are no other 64 Dart GT 273s around my area, just going to trust blind on the exhaust and xpipe . . . any specific suggestions? I am not a tuner sound guy, want as low and growly as I could get . . . I know it is not a muscle car, but like a mini-muscle sound would be great . . . suggestions?

Thanks, Mark . . . I can't get into the shop until Tuesday, but I can start the carb search!

Open to more coaching in this thread!!! And I appreciate it from all!

If yours is a 4 speed, you won't need kickdown linkage. A 3.23 or a 3.55 will work fine for your application. 3.23 will give you a little better mileage and lower RPM's for freeway use. 3.55 will get you more acceleration and higher RPM's but less mileage. your choice.....

What size wheels you have on there, Dart4forte?

 

[Rhetor]

Forgot, you also might want to swap in a solid state voltage regulator. pt #VR706 (duralast) , I did . no adjustment no hassles.

A definite do! Thanks! Thanks also for the longer earlier post . . . amazing info.

And, thanks to everybody on this thread. Getting me excited for parts buying and wrenching which will restart tomorrow morning on my day off!!!!

If you're hunting down the original 1965 cast four barrel manifold the part number is 2465726.

Numbers I have recorded from some old notes from an Offenhauser catalog are:
Offenhauser 360deg Equaflow - 5699
Ofenhauser single high rise - 5748
Offenhauser 360 Deg Dual Port - 6022-DP

Offy also made a dual Quad manifold for the early 273.

What size wheels you have on there, Dart4forte?

The fronts are 14X5.5 SBP and the rears are 14X7 SBP. Had to take them off in that the front wheels are bent. Trying to find someone that can repair the steel wheels. I have Cragers on it now.

Dude,thats a nice car pm me i've got a sway bar set up and a nice kelsey hays brake set up thanks

Thanks . . . working on mechanics now . . . running, but will run better with some attention.

Going to look into front disc brakes after it is running sweet on the current stock brake setup.

If you still have the parts then, I will get a hold of you.

Thanks for the offer!

Thanks, Grim . . . the parts numbers are so helpful, better than general advice. Cataloging those numbers in my notes now . . .

A dual quad manifold? Now, that number would be gold . . . I would be willing to invest some time and patience in finding that!!!!

Thanks, Cudamark . . . it is a 4 speed, I am willing to sacrifice mileage for some mini-muscle feel. 8)

That intake is still sold new, the trick is finding the 300CFM carbs.
