Dual DCOE 40's for a Stock 1975 2002

[Labphoto]

Hello,

 

I have a 1975 bone stock 2002 with a slush box and a Weber 32/36. I am looking to potentially go to dual 40 DCOE Weber setup. Is there any gain in performance by moving to this?

Not really, in terms of 0-60, top speed, and lap times.

 

But the grins per mile go up.

 

Plus, it looks cool.

A 32/36 is smooth and reliable. Dual 40's are temperamental to say the least. Would I put them on a tired stock motor, no I wouldn't.

Plus all above and you'd need to include a bracket in the linkage to accommodate the kickdown cable, that may be easy or hard don't know anyone whos tried.

I'd say not worth it with auto trans. Installing a 5 speed would be a bigger improvement.

Toby +1.
 

And FWIW, DCOEs are not temperamental (tune, set and forget). They don’t wander, or vary, or change from one instant/condition to the next. Where any difficulty (with a quality Weber) lies, it’s with that first step…and a good linkage.

The Weber 32/36 was supposedly setup for the Denver area, maybe I need to re-jet for Phœnix?

Denver's altitude is about 5300 feet; what's Phoenix's?  Unless it's close to that, you probably need to re-jet to a richer mixture to take advantage of the thicker air at the lower altitude.  

 

And those twin DCOEs aren't the best choice for a stock engine mated to an automatic...
