No contest -- my old 69 Mach 1, 351W couldn't touch my 69 BOSS 302 in any performance category -- except maybe fuel economy!!!

I agree about 69 models but in 70 I think the 351C mach had a little grunt.1/4 mile times were close but bottom end on the Boss suffered.  The handling still goes to the Boss as you stated. The 69 351W was a perfect street engine in my opinion.

The Boss will out handle, and is faster than a 1970 Mach with the Cleveland. However, the '69 Mach/Fastback with the 351W 4V is quicker than both of the '70s just mentioned....and a better engine...in my view. (I have had all 3 at one time).

Yep, the Windsor is a hell of a lot quicker than a Cleveland...dont believe me? Check all the road tests of the era..1969 and 1970. Also, I have owned both...the Cleveland was a dog.

I also owned all three at one time but the 351C was not stock. The 351W was still my fav.. I built a 351C for my Boss for some reason.   aah.. but now we have strokers. I have my cake and eating too.

ok, someone's smokin' crack.  I own a 351W and a 351C and the Cleveland will run circles around the W. If that dosent make sence to you,and if you followed the logic that a 351W is faster than a 351C, than a 289 HIPO would be faster then a 302 BOSS.

Ask 'Brokenboss' what he thinks.  Me thinks his Boss351 - 70 FB racer has a Cleveland.  

Dave, what do you run in that mean machine for yours?  

Nicely done car by the way.

I believe the Boss 351 was the fastest Mustang...and it was powered by a 351C....I would take the Cleveland over a Windsor in its day...with the new roller motors, things are different now....

I currently own a relatively stock '70 Boss 302, and over the years owned 68 coupe powered by a '70 351C-4V, a '69 GT350 (351W-4V) and 71 Mach 1 powered by a 315W-4V. All were four speeds except the Shelby and 3.50:1 geared.

The 351C-4V was the best engine of the group as far as outright ability to put big power to the wheels is concerened. It pulled well from 2000 RPM to 6000 RPM. The Boss 302 is very similar except less torque under 3200RPM and revs out much quicker. The Boss 302 feels about the same HP as the 351C but has a shorter powerband. Very fun to drive but takes more concentrated effort than the 315C to hook up. Too much RPM and tires break loose, too little and no torque for off the line pull.

The 351W's were solid performers but lacked the revability and wide open responsivness at high RPM's. Nice wide powerbands, hit the pedal and lots of torque from 1500RPM to 4500RPM. Easy to drive but the small valves limit the rev factor and build the horspower at lower RPMS.

Given similar cars, my experience is that a good driver with a Cleveland 4V will beat a good driver with a Windsor 4V everytime.

Im just saying in stock form daily driver I preferred the 351W. At the time the 351C had alot more potential. Now may be a different story though with all the aftermarket parts.

Your car looks fantastic, Bent.

How long have you had it?  What is the story about the car being in Denmark?

I have owned both and I would agree that the Boss is faster, not to mention more fun to drive.
