cats on a classic?
I didnt call him dumb just thought the idea was.I was extremely tired when i wrote that, so to jab at my english skills doesnt bother me.Actually i am quite capable of proper english...Anyways...the not deserving it was a tease. As better put before its just impratical.
A little tech as to why this would be a difficult task.
1). Catalytic converters work most efficiently at 700*F. While they are insulated, they can still reach exterior temperatures greater than 250*F. This requires fairly close placement to the exhaust manifold. On the earlyMustangs the floor boards would have to be modified for proper placement.
2). There is a very narrow stoichometric range that the cat needs to work in. The engine needs to run rich-lean-rich-lean-etc. in order to "stoke" the cat with fuel and then oxygen. Much like adding logs then a billows to a fire pit. In order for this to happen you needsome type of EFI.which requires a complete redesign of the fuel system.
Another possibility is to change over from gasoline to LPG. This fuel starts off by burning cleaner. State of tune lasts longer, andengine oil breaks down slower. So your overall environmental footprint is much smaller. And we manufacture our own LP gas in North America (who'd of thunk that!). You can also add a "self powered" catalytic converter which will bring the HC, CO and NOx to almost undetectable levels. As in gasoline powered cars the CO2 level does increase by adding the converter, however there is more H2O output to CO2 in comparison with Gasoline. Has to do with the molecular chain of LPG versus Gasoline.
Another advantage to LPG is the 110+ Octane rating. While the BTUs are less than gasoline, if the engine is optimized for the higher Octane number, the actual power output is darned close. The down side is a lower fuel mileage in comparison with gasoline by as much as 15% (no such thing as a free lunch).
Something to consider, and much easier to do.
Good luck with which ever way you go.
I read an article in one of the rags about a guy running a late model 6 cylinder EFI Mustang on LPG. According to the article the car scoots right along.
Give us about another 5 years and we are going to have some awesome fuel cells that will dramatically change our options. I viewed one that uses methanolandis used to recharge large industrial batteries. It's prettyneat stuff.
In any case, I aplaud your thoughts Smothers. One persons actions can directly affect a large number of people.

Awesome info Scott, many ideas to explore. If I had done my homework on the workings of the cat,i'm sure I would have ruled out the idea forall (orsome of) the reasons mentioned in this thread and not have started it.If you had answered first Iwouldn't have hada reason to check back
. I appreciateall the infofrom those of you whohad some to share. I really don't mind the negative responses, just people expressing their thoughts, not much wrong with that (sry for that pm mat lol).
Was interesting from a sociological perspective to see this unfold and turn into a environmental debate (which is not what I intended), and even more interesting to see where many stand in their beliefs. Good stuff.
Nowjust one morequestion. Is it possible to replace the top of my 65 with a solar-panel to run the electrical system so I can eliminate the need of a toxic, bad for the environment, battery? I'm going to go make myself a tofu sandwhich, then come back to see if you guys think it's do-able. -Peace out
