Boss 429 Questions

[65fastback2+2]

arguing with a couple chevy nuttswinger local buddies...they claim the boss 429 would get whipped by chevy's best corvette in 1970. Best I can find is 13.8 by the 454 vette and 13.6 by the boss 429

anyone have any better info or links?

Well documented and have seen the articles and the car Dickk Serdinak owns Portage Performance in Ohio ran in the 9's and survived many tare downs. Not off the show room floor though.

Ford 427 was the engine Id take.

I'd love to have a 427 SOHC (but that just ain’t gonna happen) in reality the 385's were the successor to the FE's and pretty much better in everyway.

To the OP's that seems to be pretty much even to me both run mid 13's in the 106-108 range. I love the good old muscle days but people love to exaggerate the performance of those cars. The biggest and the baddest street cars back then ran in the 13's and the two mentioned I would considerer a driver’s race. People like to blame the tires but the trap speeds really tell the story the 454 and 429 have no more hp the a stock LS1.

Now the most over rated engines (not by the factory but by fans) of the muscle era I would put a tie between the 426 Hemi and Chevy’s own 302. Especially that 302 they were underrated a little maybe 10-20 hp but I love to listen to people talk about how they but out 450hp (and in reality they did but that was the full race prepped Trans Am engine not the street version)

A built NA Boss 9 would eat anything built NA Chevy ever brought to the table

Some on the list have slicks and were race cars sold to the public.

Please explain.

[Uloset]

While the Hemi's were some of the most powerful engines of their times people have gone over board with the whole hemi myth. People act is if they put out 600hp stock while in reality they didn't run any faster than the other comparable Big Block offerings of the day. Again like I mentioned before a LS1 puts out about the same as the best of the best of the glory years. A good examble is the 04 GTO it weighs and traps nearly the same as a 426 Cuda.

I was in High School when these cars were ruling the streets. The L88 427 Corvette would take the 429 Boss Mustang ANY day of the week. I saw it happen every weekend. My L78 1970 SS Camaro would take the Boss 429, that's a fact. These were 4speed cars vs 4speed cars.

NO WAY! Those two mopars are 10.5 out the box??????????? If those are true, were they street cars? Because Ive seen a modded 68 Dart Do 8s in the eighth mile! Thats no where near a ten sec 1/4! Im not sure what motor he had!!! but the motor in those two were only supposed to put out 525 hp! That isnt enough hp to get a car with that bad of aerodynamics and all steel with complete interior down the 1/4! 10.5 no way! It would have to be fully stripped with nothing but a seat and a serious drag suspension!
And the 2006 zo6 in the high tens! WOW! the best time I ever saw for one straight out the box was like 11.3 or something! That car is way more capable of being a 10 sec monster than tose two mopars though! I would believe in the z06 before I believed in the other two!

[Machme1]

I could be way wrong! but those numbers are incredible, and unbelievable!

The link i posted was from a race the when Dickk was near 65. I'm telling you that his boss 429 ran in the 9's in the 70's with his tune, headers, and drags. Call him up. He still has the car last I knew, plus two other 9's. He shut many people up with that car. then there's Ohio George Montgomery, When he showed up with his 9, that was the end of story.

I don't know if anyone has seen this but I remeber when it was on speed "Muscle Car Shootout from Dream Car Garage" It compares some of the hardest hitters from 1969 including the Boss 429.

Back in the mid and late sixties I worked bending wrench putting myself through college at both a Ford and a Dodge dealership.

For the most part the Big Block Chevy's ruled the street and the strip. The 428 cobra jet could not stay with the 427 chevy. The 440 sixpac Dodge was about as fast on the street as the street Hemi and it too would take the big block 428 Fords most of the time. What I am talking about is off the show room floor. In early 1968 Ford did install the 427 in the Mustang but change to the 428 which was a 2 bolt main motor. Now the 427 could give all of them trouble for sure.

The cars today are a good deal faster out of the show room. Most of the muscle cars of th late 60's and early 70's where running in the low 14s and high 13s. In 1968 the Mustang Cobra Jet took top honors at the the Winter Pro National with a 12.5 at 97.93 (Al Joniec was the driver- I was there). It was a Ford sponsored car. - That's "Pro Nationals" - not stock Nationals....

The Boss 429 was a 14 second flat car.

These are not off the show room cars which is what I was talking about. There are Vets that run the 8s all day long - but again they are not off the show room floor cars...

I think a little history lesson needs to take place. You can't rewrite it. The Boss 429 was produced to meet NASCAR's homologation rules in 69 & 70. You are comparing an engine, the Boss 429, with another manufacturers street motor, which is just silly. When the Boss 429 was debuted in 69, it blew out the competition in NASCAR. Chevy did not win one race that year. Look up 1969 NASCAR results. The rules changed in 70's to outlaw the Boss 429 because of it's domination. Ford pulled threw in the towel in 70's because of that and other reasons. The engine that showed up in the Boss 429 showroom car was under jetted, de-tuned, and choked out. Ford could not just offer this engine to the general public. The Boss 429s did not fly off the dealer lot and some carried over to the next model year because the younger enthusiasts could not afford the insurance. Anyone that compares the Boss 429 to a 427 is just misinformed and does not know the hidden potential behind the Boss 429 engine.

Boss 351 FTW!

Maybe so but the baddest of Fords line-up were all detuned versions...the only one that wasn't was the 427 SOHC and that had to be bought over the counter....had those versions found life in factory cars there wouldn't be any discussion

What most people here seem to be missing is that few of the great musclecars ran their best time off the showroom floor. Magazine drag tests almost always used "ringers" (cars that had been brought as close as possible to maximum performance in "stock" condition) to get the best times. As far as the question of the Boss '9 goes, it is like the Mopar Street Hemi in many ways. Both were "detuned" race engines, and both were capable of strong performance when tuned to the maximum. I refer to tuning far beyond new points, condenser, wires, plugs, etc. I mean recurving the distributor, jetting and tweaking the carb(s), so forth. The same was true of the Chevy engines, with the right tweaks, they could be contenders. My preference back in the day was for Mopars, but I did respect 428 CJ Fords, they were one of the rare few cars that could give my '69 Dodge (440 Six Pack) a good run or even sometimes beat it. I never got to try out a Boss '9, but in typical street trim, I doubt that it would have been any faster than the 428 CJ.

It's been pretty well known in Musang circles that a Boss '9 off the showroom floor was a dog. A Cobra Jet would eat its lunch, and I'm quite sure a BB Chevy woudln't be any kinder. A Car Life Road Test that I've got in my hands righ tnow has a 1/4 mile time of 14.09@102.85. This has been discussed here a number of times, and the same magazine went 13.9@103 in a '69 428CJ Mach 1. These aren't the end all-be all, but are very representative of the STOCK times of those cars. The Boss was so detuned for the street that Ford left almost a while 'nother motor on the table. Built and tuned it was a solid 12 second car, but off the showroom the NASCAR based motor was not what you wanted to be caught at the stoplight with.

I agree. I had a 428 SCJ Torino and a Dodge Superbee 440 sixpac. The Dodge was the faster car in the quarter and more fun to drive. Also after market parts for the 429 did not exist to speak of. I dropped a racer brown cam, a set of long tube hooker headers, stage three 426 wedge heads, and ladder bars on the superbee and ran in the high 12s at the track. On the street I never got whipped - not even once....
