I've been fiddling with those two options for my 289 motor and don't really wich way to opt for. Maybe some could come with their inputs....

Money wise one can get a rebuilt vintage Paxton,as offered at the time by Shelby (for mustangs GTs at least not sure about cobras?) for about 2500.00 and webers (44 IDFs) with the manifold about 3200.00. Plus of course the xtras for each options.

The power gain seems to be definitely on the Paxton side with a claimed gain of about 30 % while the webers are to bring-in less H.P. Question: Am I right to think the apparent gain from the supercharger would be there only at higher RPMs and at contrary the webers would deliver xtra power at all RPMs?....In a much shorter/direct way to ask what would just be more of a kick to drive?

The use of supercharging apparently carries a constant dammage risk to the motor if detonation is not well under control at all times.....isn't a similar situation with webers carburation? If not for detonation isn't there another concern about webers that oblige one to always worry about a right level of tuned-in situation?

Does anybody would know why the Paxton was offered on Shelby mustangs and not on the cobras proper? Is it it came after the cobras years? Or would it be that supercharging wasn't as efficient a system as webers cars when racing was the intended use?

After all considerations webers tends to have my vote...but gee that ole cobra paxton installation is kind of nice also....what you think?
