Hehehe, this is kinda funny. An argument comparing the superiority of the 4.6L DOHC 32v V-8 to the 5.7L OHV 2v V-8.
Well, where to start off? Engineering. Best not hit redline with that LS1, unless you plan on buying a new motor from bent pushrods and valvetrain parts. How much power/streetability do you really think you can get out of an LS1? All a Cobra needs is a street trim S/C and it'll run 11's all day long for 100,000 miles. The Cobra can rev to 7k without problems, stock, beyond without the damn rev limiter. It has 4v per cylinder and DOHC. Meanwhile GM is still building OHV 2v's. I'm not saying you can't get good power out of a OHV 2v engine, just there is no way you can match the 4.6 DOHC engine in potential. The Cobra motor is just sitting there, detuned all to hell waiting for some mods.
As far as why the Cobra was discontinued, that's because Ford changed design at the last moment. Basically they mismatched a combo, and the cars were only making 305hp still, instead of the claimed 320.
The only reason the Cobra has the kind of power it does is that Ford likes their cars to hold together for a long time. It's not like they couldn't get more out of it. All you need is gears and better rubber to run as quick or quicker than any stock LS1, anyway.
The LS1's are damn quick stock, but they are by no means some engineering marvel.
Where to end, like it's even a question. The 4.6 is so far superior it's not even a debate.
Oh, by the way, I've beaten stock LS1's with my near stock 87GT. Vert's but still beat them.
'Course, how can you expect anything different on a Mustang website?
