def. the ford mustang 429, that is my fav. car so it will win

Have you tried reading this? Use commas!!! They are there for a reason!

only if the yenko was orange .

Yenko for sure!!!!!

My head is spinning. I’ve seen Yenko Nova’s run stock and was pretty disappointed. Not sure about the Camaro though. I’ve seen stock Boss 9′s run in the high 13′s. Stock that is about as good as they will run. Ok, lets round them up and race them.

Ummm… Eldorado….Shelby Cobra’s never came with the 427 SOHC. First they came with 260′s, then 289′s and then 427′s. Some actually received 428 motors. And in no way in God’s green earth did a Yenko 427 Camaro ever run 10 whatever you said. You have to make big time horsepower for that and you’ll definitely need traction devices. Stock no way in the world. All these old muscle car myths are funny. I have had Mopar guys brag about Hemi’s running 12′s easily and even 11′s stock. Funny thing was when we had Mopar day at the track most of the Hemi’s ran in the 14 sec zone. A few crept into the 13′s. A lot of those cars weren’t as fast as everyone thought. Some were definitely quick. The thing is you had so much motor and could easily make the car go faster.

I’ll tell you which one is worth more. There is a Boss 429 on ebay right now for $295,000!!

Hey exesquite or whatever. You obviously don’t know anything muscle cars and no less about Boss 429s. Were did you get that 69′s Mustangs were the slowest? 69 Might have been the best year for the Mustang. The first full year for the 428 Cobra Jet, Boss 302 and the Boss 429. Actually the early Boss 429 motors (either S or T motors forget which) ran the best. You said unless its a GT500. Well the 69 GT500′s were slower than the 67 or 68 models mainly because of the weight. Where did you get that the Mustang had a low end torque advantage? The biggest gripe against the Boss 429 was it’s lack of low end grunt. This isn’t a 428 we are talking about. I was also making the point with the Hemi’s by saying not all these old muscle cars were as quick as we thought, there are a lot of fish stories out there. Everyone thinks just because something has a Hemi in it the car is fast. I’ve seen plenty of Hemi’s run 14′s and even 15′s.

well in reality the yenko made more like 500 horsepower at the flywheel, which turns out to a hell of a lot of power to the wheels. now im not so sure about the boss, but im almost positive the camaro weighs less than the stang. so my bets would go with the camaro.

All i know is what I read in old HotRod Mag., the Shelby Cobra with a 427 Overhead cam motor would do 0-100, back down to zero in 14 sec. The Camaro 427 SS Yenko (1969) would do 10:29 in a 1/4 mi

No one can definitely say one vehicle will beat another using advertised horsepower as the only criteria. At a strip in Maryland in 1977 I saw a bone stock 4 cyl. Vega beat a wheel standing Chevelle because the Vega had an eleven second head start on the Chevelle. I’ve seen small block whatevers beat big block whatevers at numerous strips on the east coast. Too many variables to say this car will beat that car.
Oh yeah, learn about punctuation.

My vote is for the yenko since I own a 69SS camaro and am a chevy fanatic . Ive had my car since 1982 and its fully restored and garaged always . Its white with the double chrome injector hood and all the chrome options for the ss . I will admit my first car was a 69 mustang but it just isn’t or wasn’t the car my camaro is . you know they say that the camaro is the poor mans corvette well i have 11,000.00 invested in mine . Id rather have my camaro, the only corvette that compares is the 63 split window my dream car.The yenko will definetly run and hide from any ford.

1st the Mustang has more Torque off the line, but a Yenko will be the light weight car so it will beat the mustang by a 1/2 car through the 1/4 mile.

but the Yr of mustang your mentioning is slow, unless if its a GT 500 series.

& ” i don’t know what the F#$k a 4 cylinder what ever
or Hemis have to do with your Question.”

Dumb.

It’s a total toss-up. The Boss 429 ran 13.60@106 dead stock. The COPO 9561 Camaro, which is the car that was used for the Yenko SC ran, 13.50sec @ 102mph. You can’t really compare horsepower because most manufacturers were sand bagging h.p. ratings in the late 60′s. The 1/4 mile e.t. listed for both cars are the original ’69 Road & Track test figures.You also have to realize that these cars were trying to hook 450+ h.p. on 7″ bias-ply tires, so performance could vary substansially from one pass to the next.

im a GM fan here but im going to answer your question unlike some people here already deciding the outcome because its their faveriote car. the yenko IMO would win because the 427 block it has was pushing more HP then it was rated, and an aluminum block gives it a way better weight advantage then the mustang. the 429 is a step down from the 428, that engine though powerful is considered a bit of a disapointment from the previous years 428 which was way better.
