The words "best muscle car" is nothing more than a matter of opinion. There are several basis that the question could be asked under like.....Fastest muscle car, best all around muscle car ect... Point is, none of these take any honors but all three are very nice;)

[mike02ex]

[Got nads?]

1970 Chevrolet Chevelle SS, 1969 Camaro SS, 1969 Dodge Charger, 1968 Hurst Oldsmobile. These are nice cars, no mustangs allowed!:devil:

No factory 351 cubic inch or smaller could even so much as come close to eating a boss 429. Fact.

Trivia question: What was the 1 and only year that a 351 boss came in an automobile and what kind of car was it?

[mike02ex]

mustang or torino,68 or 69

Close, really close. You got the car right, what year?

[mike02ex]

torino, 70? i dont recall exactly

[CRE Performance]

72 Gran Torino Cobra Jet. Just about one of the ugliest of Torinos or even Fords for that matter:D

[mike02ex]

yes torinos were gigantic!

i have a 429 supercobra jet that i'm restoring right now, and also have a boss 351 but havent pitted them against eachother so i dont know first hand, but listen to this---

"On paper, the ultimate Mustang for 1971 was the amazing 429 Super Cobra Jet. But the real sleeper was the Boss 351, which had a 330-horsepower version of the 351-Cleveland engine. With raim-air induction and less weight, the Boss 351 could eat the 429 for lunch. As was the case with many muscle cars, the hot Mustangs engines were quickly disappearing at this time. The 428 CJ and Boss 429 were casualties in 1971."

this is straight out of "American Muscle Cars" written by Jim Campiesano - fact

Fact- I do not read publication other than pure tech publications for updating purposes. If I say something about a car (especially a Ford) I am coming from FIRST HAND EXPERIENCE, not something I read about. I have built several of both engines, driven the cars they were put in, tested the cars at the strip. THE TRUE BOSS 429 WILL ABSOLUTELY CLEAN ITS CLOCK. If you had ever driven a stock cleveland powered car, youd know what im talking about.

Also, the 429 Super Cobra Jet will also cut the balls off of a 351 cobra jet.

you calling that guy a liar or... i'm not sure what your getting at.

this is a good book with a lot of information i know to be true so i wouldnt even think to doubt that little passage i posted.... unless your comparing the engines side by side, no drag racing or nothing, just going on #'s alone?

What you are failing to understand is the torque difference between the two engines. Torque is what wins races. Power under the curve is what wins races. That cleveland in some instances may match or come close to peak power #'s of a big block, hell it might even come close to a peak torque #, but there is no way is has anywhere near the power under the curve, which wins races. In my opinion, theres no better way to judge and engines ability than to compare by its power under the curve. Just because you read it in print doesnt mean its correct. When I was young and used to read publications as such I found as much false information as true. Dont take it as the gospel.

[nosliw]

i understand torque, that's why i indulge myself in these cars :devil:

i'd imagine that passage was from first hand experience, i mean noone would just put that there without making sure.. especially in such a good selling book. i dont know

stats on both 1971 engines (according to the gospel ;) )

boss 351

hp- 330@5400
tq- 370@4000

429
hp- 370@5400
tq- 450@3400

those #s sound right. i mean they arent trying to favor the boss over the other by any means. what they said that separated the 2 was the ramair and lighter weight.

any other commentary or is it still "book's wrong"?

[CRE Performance]

Let me put this in a little more understandable form.

The 429 SCJ only weighs in at an extra 90lbs over the cleveland. Both cars are standard with C6 auto trans ( same weight) (90% of cleveland cars came with C6). It takes right at about 20 HP or 10 ft lbs of torque to overcome 100 lbs of weight as far as lateral excelleration is concerned using the weight of the two cars. This means that if the torque numbers were the same, it would be an almost identical drag race, however, that extra 70 ftlbs of torque that the big block would be making after the wieght ratio was figured would stomp off a mudhole in that cleveland;) Even ignoring the fact that the 429 makes a lot more power under the curve.

[CRE Performance]

Also, thier BHP figures were taken after the ram-air was added, not before. So its not like you have 330 HP plus another 10 HP that the ram-air gives.

replace the cleveland with the boss that im talking about how big a difference would it make. i'm taking my boss out to the track this weekend so anyone in the area with a 429 like to race and we can get this squabble over with? :D

[nosliw]

this is a message i got from a friend to get another opinion on. feel free to comment

"I feel that the 351 beating the 429 is completely believeable. Almost all muscle cars were underated from the factory,some worse than others. For example,a Ford 427 Medium Riser from a Cobra was rated at 435 hp. On Fords own dyno it made 585 hp in factory trim minus alternator.You also have to consider the 351's ability to rev slightly faster."

A Boss is nothing more than a glorified cleveland. Believe it or not, thiers not much HP difference. Most clevelands had 290-320 HP. If you could read and understand my last post thier would be no need for you to squabble anyways.

[nosliw]

and also if it makes a difference non of my muscle cars are automatic except my pontiac. but i dont know if that would change the outcome if both were standard's

Fords #s were underrated. However, your buddy is ignorant if he thinks for one minute that a 427 in factory trim made 585 HP on anybodys dyno. As far as revving faster, those cleveland pigs had such huge heads on them they wouldnt rev for **** until they passed 5000 RPMS. Argue all you want, I dont know anything about cars. Ive only built race engines for 10 years, Ive only worked for Ford Motor Company for years, Im only certified higher than anyone in your home town, If only got 4 colleges after me to take over instructor positions in the automotive dept. Thats right, a 16 year old with a David Vizard book can absolutely school me on Ford engines.

[nosliw]

impressive. glad your not a pompous *** about it :rolleyes:

i'm done, i need to go work on my 429cj so i can get some of this first hand experience myself....

http://img62.exs.cx/img62/2254/arguingoninternet4ay.jpg LOL!! love that pic...

[CRE Performance]

Look dude, I was only trying to broaden you mind a bit as far as engines are concerned. I wasnt trying to break you down. However, when the buddy thing gets brought up and you trying to bring in another false statement to try to prove me wrong, yes, I turn into to a pompous ***.;)
