i havent seen a 427 cobra jet run with a 440 magnum 426 hemi or a 572 gm crate motor they all blow away the 427 crobra.

 

You have got to be kidding me, how come no 440 magnum, 426 hemi or a 572 gm crate motor went up against the european cars and beat the pants off of them like the 427s did in the 60s?

I just found this

"In an attempt to improve upon the speed and handling of the 260/289 Cobras, Shelby and Ford collaborated to build the 427 Cobra, which many feel was and is the ultimate street weapon. The 289's leaf spring suspension was replaced with a computer-designed coil spring setup, and the small-block V-8 was replaced by the powerhouse 427 sideoiler V-8. The bodywork was stretched to cover the widened suspension and tires, creating one of the most muscular bodies ever seen on the road. The 427 became famous for its acceleration; legend has it that Cobra team driver Ken Miles accelerated from 0 to 100 mph and braked back to 0 in 13.8 seconds. 348 427 Cobras were built. Originally sold in either race or street form, many race cars were converted to S/C ("street/competition", or "semi/competition") models, which were street legal--barely. These cars are generally considered the ultimate 427 street car, and most replicas emulate them.

Although Shelby never seriously developed the 427 as a race car, they didn't do too badly, either: 427's won the SCCA ARRC A-production championship in 1965, 1966, 1967, 1968 and 1973. As with the 289 Cobra, the 427's were available in drag-racing form and, known as "Dragonsnakes", set many NHRA class records in competition."

 

I think f1001978 hit it well enough, 0-60 4.0 secs, and I read it was 0-100 then back to a stop in 12.8 secs which is funny cuz the 435 hp 427 vette wasnt able to crack 100mph in 13 seconds let alone stop. Heh also if you want a real shocker Carrol built one for Bill Cosby with two Paxtons on it , and built one for himself the same way, and it ran 0-60 in 3.6 secs. Now that sounds kinda quick to me and btw maybe the reason you havent seen a Cobra run with a 440 426 572 is that its hard for those 3 to run with something out of their league

 

Whoever stuck that chevy engine into the cobra was retarded. These are the same idiots who will replace a ferrari's engine for a chevy 350. You cannot reason with them because they have no imagination no clue.

 

I'm actually in favor of swapping in American V8s into older (1970s, early 1980s) Ferraris and the Jaguar XJ-12s. The motors that came stock with them were often unreliable pieces of crap. There are Broncos that are faster (0-60) than stock Ferrari 308s and my friend's Ferrari 512 Berlinetta Boxer brakes and corners poorly at best. Still, it is a gorgeous car. I do think it is silly to swap Chevy motors where a Ford motor should sit. Like the idiot I saw at a D.C. hotrod show who had a 350 stuffed in an old F100! Aaaaaaaagh!

 

Well yes it all comes down to where do you draw the line? If it's OK to swap Ferrari, Jaguar engines for Chevy's 350 then why not the F100?

 

Thats horrible, but I bet that car screams. If kit car builders are putting a stock 225HP 5.0 mustang engine in them and getting 4 second 0-60 times, than I can only imagine what the C5's LS1 can do.

 

I draw the liine at practicality. Older Ferrari engines are unreliable and needlessly complex. A tune-up is easily $3000 and 30,000 mile maintenance can be $10,000. A rebuild for a 308 motor is $13,000. That's why people swap the engines in them. They want a nice looking exotic car without the needlessly ridiculous maintenance costs. Not everyone who owns a Ferrari or Jag is rich. Now the Chevy-into-a-Ford swap baffles me because for every application where a Chevy 350 would work, there is a Ford 351 that would do just as well, with reliability and potential for power being similar.

 

Well then speaking of practicality. Everyone here is well aware that Chevy 350 is significanlty cheaper and cheaper to hot rod. So than the Chevy inside the Ford makes more sense right?

 

Please only use this forum for technical comparisons of ford vs.the competition. Thanks.
