Richard Holdener tested a replica Boss 302 on the pump and it's about 374 hp.

[@gt-37guy6]

Then the quarter time for this Boss 302 would have to be in the high 13s wouldn't it? Does not add up whatsoever.

[@boneseyyl1060]

A replica?

[@1967davethewave]

@@gt-37guy6 Holdener tests the engines on the dyno with open long tube headers, electric drive on the water pump and usually a modern Holley carb that is jetted spot on. I believe that 374hp might be the ultimate potential of the Boss 302 if tested like that but as installed in the car probably 75-85 less gross and 130-140 less net maybe? That would make it about 240 at the wheels which would explain the 94mph trap speeds. I was actually surprised it wasn't at least in the mid 14 second range with those 4.89 gears.

Wasn't that the 351?

G’day C& Z, Great to have you back mind, body & soul & that video is just CLASSIC CLASSIC C & Z, all the way. Back to your all time best with your comments, surprised being a Boss Mustang you didn’t play any Bruce Springsteen “ The Boss “ music in the video, I was expecting it. Now being an Aussie, if I was a muscle car I would have to be an Aussie Muscle Car. Now being born in 1970 it would have to be a 1970 Aussie Muscle Car, & I would be what I have. 1970 Valiant ( Mopar ) VG 770 Hardtop, mine has a 6 cylinder HP Hemi, but I would order the factory V8 with the 318 Fireball. Then in 1971 I would get a heart transplant & get the 340 @ 275 hp shoe horned & out with the 318 2BBL. The 770 model was the gentleman’s muscle car similar to a GTX or Coronet R/T. If I was an American Muscle Car, for me one choice & a 1 of 1 build but you could order it. 1970 Plymouth Sport Fury GT with a 426 Hemi, centre console, dual mirrors, vinyl roof with 3:23.1 Limited Slip Diff with the biggest tyre & wheel combo, effortless driving at 120 mph. That’s me love my big cars with lots of power. So being an Aussie get the best of both world both Aussie & American Muscle Cars. Great to have you back. Cheers Louis Kats your number 1 Fan in Melbourne, Australia 🇦🇺 🇺🇸 👍 🍺

[@lobotomyboy666]

I used to write for Motorcyclist Magazine and when I went down to the garage to pick up test bikes in the Petersen Tower on Wilshire Blvd, that 1970 Hot Rod Boss 302 test car was still sitting there, collecting dust. Man, did I want to take that out for a drive! But since I usually had a new Harley or Ducati or something very cool waiting for me, I never checked it out closely.

[@AtZero138]

How Cool.. also.. dang huh.. just sitting there.. Cheers from Orange County California 🇺🇸

[@W1se0ldg33zer]

These times showed the difficulties of trying to get traction on those bias-ply skinny tires and why lots of cars back then all were running 14-15 second times.

[@johndillinger8482]

actually the bias plys work better than radials.

[@ShiddyFinkelstein]

Regarding automatic transmissions, at the time these cars were produced, nobody I knew of including myself would ever have ordered any of these muscle cars with anything less than a 4-speed. Obviously automatics have improved greatly and are much more efficient now. Loved the Boss 302s in 1970.

[@AtZero138]

[@nicholasselvaggi54]

My 2005 Grand Prix GXP had a 2.92 final drive, could hit 90 in 2nd, and caused me to not hit 100 mph in the 1/4 mile. However, with 270 hp and over 300 lb ft at the wheels, it pulled a 13.9 with a 1.8 60 ft. Not bad for a supercharged V6 transmission. Superchips tuner, K&N intake, shift kit.

[@culcune]

I am in the same boat having owned a '68 Cougar and 3 Fox body Mustang 5.0s; but for cruising, and comparing these two particular cars, an automatic with a what I would hope has optional air conditioning would be more desirable. Heck, commuting to work and back using a vintage car today would find me preferring this Challenger over this Mustang.

[@boneseyyl1060]

In the late 70's I had a 1970 Cutlass and my friend was driving a 71 Challenger. Given to him by his Dad, it was a 318 dad car but still nice. One night at my girlfriends apartment I got stupid and decided to race up the top of the 2 story parking ramp. I didn't get very high at the top but came down hard. Ended up the frame was cracked. Not to be outdone my buddy decided to do the same thing (he was much crazier than me) only he decided to do it going DOWN! Needless to say he flew off the end of that ramp and landed somewhere at the bottom, probably a 10 to 12 foot drop. Woke up everybody in the apartment and he manage to just drive it away somehow, before any cops showed up. That was the last I saw of that Challenger, since he never had the money to fix it and in those days, they were just cars, not the collectors they are today. Crazy times.

[@jeffschwartz5199]

I'm a Ford guy too and would like to have a few Mopars 👍

[@wymple09]

The 383 was the best engine Chrysler made. These 15 second times for both cars is far more realistic than all the modded stuff that gets bragged about. This was my heyday and the biggest myth I see is the "giant killer" 340 Mopar crap. They ran decent, which was only in good tune, which was almost never.

[@1967davethewave]

The best thing about the 383 was that it seemed to respond extremely well to the usual modifications in my opinion. I have owned several and they would go from 15 seconds bone stock to mid 13's with just a cam, intake, carb, headers and a little tuning. No head modifications or increased compression. And they had to have been the most durable Big Block ever made.

[@wymple09]

@@1967davethewave Everybody had durable big blocks in that displacement category.

Agree a bone stock 340 wasnt impressive. Not many of these were Didnt take much to make a factory new one run better though . Tweak the dist, timing get rid of the lean as a popcorn fart tune headers they all ran strong

[@danmyers9372]

@@CarsAndZebras - I don’t buy the 14.9. Betting that time was by a magazine writer who wasn’t that good of a stick shift driver (that was VERY common back then). I owned a 1970 Mach 1 with a 351 W auto back in 1973 that was lightly modded and ran consistent 14.7-14.9’s. I raced a couple Boss 302’s on the street and while I could get them off the line with my 3.91’s and more torque but after about the 660’ they would just pull away from me.

I was humbled by my buddies stage 1 in my 70 Chevelle SS 396 4 speed car. I had 90k miles on the motor and added 2 quarts of oil weekly. I spun a main bearing while sitting at a light after work one day. It was fine until I let the clutch out then Bam Bam Bam! Another buddy had a garage and raced an Altard and had collected several BB 427's. I bought one that had big 66 heads and took it to a local machine shop to go through the motor. It was nasty. I also swapped out the 4 speed and for a built turbo 350 with a 3500 stall converter and added 373 gears in the rear end. I went from 16's to 12's on Firestone Polly glass tires. I then got revenge on my buddy. RIP Willard Cogdale. You were an amazing friend. 🙏

Power/weight ratio makes all of the difference. By the 1970’s, most muscle cars were too heavy even with hi-po small block V8’s. Those with bigger engines were more powerful but way too nose heavy for any serious road racing.

[@mrkemblegilstrap]

A surprisingly good match up. I gotta say, that even though I`m Mopar till death, I got goosebumps when you said 4.86 gears in the Stang. Which in themselves should have taken at least a full second off of its ET. With 10.5 CR, 4.86 rear, 7k red line. I wonder why the Max HP was rated by Ford at only 290@5,800 RPM? This was before the insurance companies got in and everybody started fibbing about their HP ratings. I`m guessing that a 350 rating would not have been too far out of a possibility. This all should have made this Stang a beast. Not a dog? I`m guessing that traction was his problem? Yeah, the Stang won. In reality it should have dominated. The Challenger could have made a better showing. Was this the basic 383 four barrel and not the Magnum? Despite the only 5 HP difference on paper, the 383 Magnum is a ton faster than the 4-barrel version. Despite the disappointing times, these times were very reflective of actual times turned in by these cars from back in their days. Beautiful cars, great races. Thank you.

[@gordocarbo]

DIdnt know there were differences on the basic 383 or magnum? They were like a much bigger 327. Short stroke big bore. Great for a fun driver but not much torque for a heavy car. Back in the day the st race crowd didnt have a good opinion of them...same with 428 stangs

[@happycat0411]

Those are REAL quarter miles numbers for like a stock BOSS 302 Mustang and stock 1971 Dodge Challenger R/T with a 383 CID! I remember seeing a 1/4 times in an old Hot Rod magazine for an experimental 1969 & 1/2 T/A with a RA V 303 and the best it could do was a low 15 second quarter so these times are very close to what performance small blocks (Z28s, BOSS 302s, and 340s) could actually runl

You're thinking of a 1972 Challenger, the 71 had 335 HP.

[@JrGoonior]

Nope, 1970 was the last high compression 383 with 335 HP, the 71 383 was detuned to run on regular gas with 8.5:1 comp ratio, that's why it's only rated at 300 HP and was the last year for the 383, it was replaced by the 400. There was no big block E-Body in 72-74.

[@shawnturbeville994]

This 383 needed a good tune up. A good running 383 would easily turn mid 14teens. I have never seen a stock Boss 302 that ran good. They wouldn't fall out of a tree. They had no low end and were nothing to shout about when they did wind up. They were like the Boss 429. They had potential but stock they wouldn't do anything. Both the Boss 302 and 429 were lucky if they had the advertises horsepower stock.

Best 1/4mi of 14.22@ 98mph (DA 4200, 104 degrees outside) on 225/65/17's (798 treadwear so traction was an issue). Trying to get it to 14.0, but fighting with the stability control/ torque management to let me have full throttle in 1st gear (best 60' has been in the 2.26 range, but it'll only do that once or twice before the ecu kills the throttle response and starts yanking timing).

The reason the Challengers didn't sell is because there were 2 trains of thought on it: 1. It looks like a bargain basement version of the Hemi Cuda and 2. It also looks like a Charger that needs to go on a diet.

[@scottrittenhouse3131]

It was about 300 hp , the mustang

[@billygarner8318]

Come on man, 15s, we need speed!!!

[@gunguru7020]

Daily driver with 30k original miles.....he work next door and only use doordash?

[@flycatchful]

It is all about power to weight ratio and who gets off the line first.

[@SolamenteVees]

You could also get a 340 (extra cost option over the 383) 3:55

[@doolallyproductions7234]

I really feel like ford inflated alot of their cars HP numbers

[@TheGman54321]

big block vs small block..

[@nicholasselvaggi54]

Yes. 😁

[@jdecker9834]

Ok, I'll be the **** that's hard on Z here. First, we're all glad you're back but 1 vid every 11 days won't feed daddy's shameful needs. And then you give us these beautiful cars running 15s? I had to check my settings to make sure the playback speed was set to normal. Now I too know what my wife feels like while I'm eating that aforementioned sandwich.

[@gordocarbo]

Its a free vid, sure he has a life and cant put them out all the time for us.

[@johnfitcheard7112]

You could get a 340 also in the r/t

[@danielmenefee1943]

I am adding this comment before I see the race and I feel very confident that’s a 71 challenger will win relatively easily because well it just should. I mean at the Mustang was a boss 351 it probably be a different story, but we’ll see.?

[@holyroncg]

Ford guy here.

[@absoluteclownworld]

My 1992 civic si with a ebay turbo kit blows the doors off these 2 muscle cars.. geez

[@gordocarbo]

Was there a turbo civic in 1970 no so whats your point? Got any timeslips to post

[@davebarnes6672]

Funny and entertaining.

[@cykill9897]

Like to see a 71-72 dart valiant race somebody

[@markg7030]

The Challenger should win but the Mustang is way ahead. Lets see.....................

[@manher4335]

Bleh... That's all the legendary Boss can do!? Couldn't ctack 15s? Wow. Z28s broke into mid/low 14s habitually. Meh. I always felt the Boss 351 was a much better contender

[@marioncobaretti2280]

Last year for 383 and the only year for cast crank

[@peep39]

I could take that challenger with my 05 Ram

[@davidlefranc6240]

Funny fact a freaking 2002 ford focus run 16 seconds on the quarter mile not really impressive, still nice video !

[@JrGoonior]

My 2005 PTCruiser GT turbo runs times similar to these, mid 15's @ 85+ mph.

[@1967davethewave]

Many people state this, which is fact. But a 383 in Challenger with a few performance parts will go mid 13's at 103-4. And get a little spendier and add some really good heads, a bigger cam and intake and low 12's are right there. And there are 2 bigger engines you can choose and get similar but larger increases from. In 2024 you would be hard pressed to find a completely stock 71 Challenger out running around to race in your Focus or PT Cruiser. But it would cost very much more to match the old muscle car in modified form with any modern front drive car. Oh sure, it can be done, there are Civics running 10's, but it was so easy to do on the old cars.

[@LtJackboot]

Most of us real men swapped out the th350 automatic for a Muncie 4 spd.

[@johndillinger8482]

embarrassing Et's,but the boss 302 ran what it actually did when new.
