As for 1/4 mile times, Zora Duntov was much more interested in Can Am racing than drags. He could have cared less. In fact, he was very much against the big block. He wanted a car that would handle in the turns. Zora was the guy behind the Grand Sport Corvette. That was the sb that owned even the 427 Cobra. That's all he cared about. It was the marketing guys who insisted they needed bb for rediculous 1/4 mile times and nothing else.
There's many more brands of cars on the market now and so the sales volume of a particular model has to be pretty good in order that Ford, for example, can produce SVT cars. They have to sell 250,000 V6 Mustangs in order to afford production of the first Mustang Cobra. That's why they aren't always offered for sale each year. People want a variety of cars today and aren't satisfied with a variety of engines in a few cars.1973mach1 said:Back before 1974 it seems Mustangs had so many more options then today, you had a big choice of engines: 429's, 351'sC, HO, CJ, 4bbl, 2bbl, 302's, I6's, 390's, 428's, 289's...Sometimes 5 or 6 a year to choose from. 4 different trannies, whole bunch of rear end ratio's. Now you have a choice of a v6 or a v8, a auto or manual. Not much to choose from. Why don't they give us more of a selection? I wonder what kind of power the engines/cars would have been pulling if the OPEC, Insurance, and emissisions had held of for a few more years.

L88 bb with nothing more than headers have been shown to run 11's @125
Just for the record here, I have an issue of Car Review magazine where they track down the 50 fastest musclecars from 1961 to 1973 eliminating modified cars and factory ringers.The fastest small block car in their list is a Boss 351 Mustang at 13.80/104MPH while the LT1 Corvette mustered a 13.92/104.Seems to me that on any given day either one could probably beat the other so it is hardly worth arguing.
blkfrd said:There is one 351C that hasn't been mentioned and it was one of the fastest production cars that anyone made. The '71 Boss 351 ran consistent mid-13s at about 105 in stock form. All the mags that tested it were running similiar ETs. This car was well into the list of the 50 fastest production cars of all time. That was with stock manifolds and mufflers. Now if that car had open headers, it probably would have been a sub-13 second car. It takes a lot of HP to do that in a heavy '71 mustang. Probably in the range of 400 or more at the flywheel.
I didn't see the 350 vette in the list at all. The 66 427 vette and the 62 327 vette were in the list though.
RacerX said:The way I lookat it is, 351W=has potential, 351C=has most potential. Why wouldn't you want the most potential. Upgrade as the $$ comes available.
Dude, I don't know where you got your info from but the Grand Sport never owned the 427 Cobra.I'm a corvette fan from the early 60s. The two cars were pretty well matched but the GS, more often than not, fell to the cobra.
If there were turns on the race track, 427 cobra's generally lost to the Grand Sport 'Vettes.....that's fact. http://www.grandsportcorvette.com/gs/
Furthermore, 72 351Cs were still potent but milder than the 70 & 71 4Vs. I'll see if I can locate the info but I'm sure the cams and timing were changed for emmissions. Clevelands have always been an engine that bowtie people have been hesitant to tangle with.
the 352 was released in 1958, the Windsor came out in 1968 in Canada, and 1969 in the US....the Clevo came out in 70, and the M came out in 1974Edbert said:I though the 351W and 351C both came out in 69?
Why did Ford kill the Cleveland? Only one correct answer (not talking racetracks)....OPEC!

Finally, and this is rediculous how Ford guys will not EVER concede anything to a Chevy (and vice versa by the way), but if anyone decides to really look at the numbers, the real number, there is simply no way to claim a 351C from any year, was beating up on a stock LT1 350 from Chevy. Guys, it's simple, LT1's produced 370 hp in their hayday! Clevelands might have hit 320 in their best year. That's not even close. I just don't recall the Corvette guys exactly shaking when lined up against a 71 Mach1 with a 351C.

D.Hearne said:Uh, one mistake in your post 69Stang-- the Cleveland was produced for 5 years here in the US, 1970 thru 1974. And up til like 89 or so down under.( I may be wrong on that, but I know it was sometime in the 80's)
Maybe Blown4.6 got the LT1 confused with the Aussie GTHO motorozstang65 said:XY GTHO Phase III 351 Cu In 4V Cleveland, Holley 780 cfm 4 barrel d/draught
