I noticed a guy in my home town must have got a real nice Roadrunner recently with gorgeous mopar green and black paint job. Looks mint! I never seen it before in my 19 years living there. LOL I seen him on the street occassionally and its a matter of time before i run into him at a light. Hell, if i meet him somewhere i may ask him to race me LOL

My 89 Irocz running high high 13's now. The car is stored now for the winter so this is just for future reference for next spring/summer. But yeah, i got maybe some 13.9's in the car or possibly faster especially once i get my 3.27's in.

This Roadrunner sounds and looks pretty stock. Pretty sure its a 440 but could be 383 and i doubt its a hemi. maybe minor work done to it like a rebuild and usual Edelbrock stuff. Hes got stock rims i think, 15" with BFG radial T/A's. Looks like a stock restored car. I seen him get on it once and it moves good.

I know its hard to tell with out knowing exactly what he's got under that thing but what do you guys thing about this? Could he be somewhere in the 13's as mostly stock car? I not to sure on this as i dont trust most muscar stats i seen, cuz they vary too much. some say 14's some say lower 13's.

 

Go for it. See if you can put that mopar down. If its truly stock, you may just stand a good chance, even with crappy gears. Besides, you know what mopar stands for, right?
Move Over People Are Racing

 

ok after looking at some pictures it may not be a roadrunner after all. Could be a Dodge Super Bee or indeed a 69 Roadrunner, or even a GTX. dont remember exactly what it looked like now. So many mopars! LOL

 

If its a 69 Road runner watch out and try to find out if it has a six pack, three 2barrel carbs. Its one of the fastest stock muscle cars ever. Mopars where known back in the day to hook well on the street and gave my dad in his 442 some bad beatings back in the day. Mid-12s stock if its a 69 1/2 road runner, but it all depends on what he has.

 

Yes, do use "one of the fastest muscle cars eveR", as a plural term, as there is a car much faster......70 Chevelle SS LS6 ring a bell? :hail:

 

me thinks that no matter what engine he has if its a super bee or a roadrunner you will lose. but id trade one of my bowties not the elco but any of the other ones for a nice mopar chrysler any day 71 cuda 68-71 roadrunner superbee daytona gtx o and a hemicuda will beat a zl1 maro and a hemirunner would run just along side with a ls5 6 but not an l88

Never liked the dodges. The older ones are much better than what you see nowadays though. The local dodge dealership was giving away a new truck a while back, and I entered the raffle. My dad asked me why, because we are all anti-dodge. I told him its simple, I can take it to the chevy or ford dealership and trade it in!

 

Hemi Road Runners (425hp, so they said) ran low 13s back in the '60s. The 440 (4bbl-375hp and 6bbl-390hp) ran low 14s, and the 383s ran mid-high 14s. The 4-speeds were somewhat faster than autos.

A healthy L98 does stand a pretty good chance against a stock-ish Road Runner if its got a 383 or 440. If its got a Hemi, move over

 

yea but i bet that rr has radials now and not bias ply gumballs for tires

 

It has Radial T/A's like most all muscle cars have. I seen the tires as i went passed the car and noticed that it has those kind of tires. Still, it should be a fun race if it ever goes down!

 

well radials would give him an .5 at least over stock bias at least prob more to a sec it would be fun just to see him run but dont plan on keeping up with him

 

so what about an 383 then? high 13's?

 

id say mid or deep13s more like mid but i bet he has an exhaust prob intake and cam so id say deep 13s but if its a stocker mids

 

Stock all the 440 Roadrunners, GTX's, Chargers, Corenets,and what not ran mid to hi 13's. With the torque of a 440 I think it would take slicks not radials to make a big difference in traction and ET's.Oh ya jocww. It was the S/S Barracuda that could beat a ZL1 camaro not the plain hemi cuda

 

Here is a site on the hemi Cuda's. Looks like they might not been as fast as we may have thought.

I always loved the Road Runners. When I was a kid one of my neighbors had one and he would always hit the road runner horn when he drove by. Made my day when I was 5 haha. I think it would be a really good race if you could find him again. Hopefully you can kill him out of the hole with a good launch and he'll sit there and spin. Good luck and definitely let us know if you guys race. If you don't, ask him what he has done to it and if he has any times from the track.

I am going home this weekend and my car still has insurance on it. Couldnt drop it till start of December so I still can drive. I will look for the guy and see if i can find out about his car. LOL maybe set something up.

 

Keep in mind guys that most of the "as tested" muscle car ET's were on tiny fiberglass belted tires with crap mufflers, paper air filters, etc.

I watched a stock looking 440 single quad road runner with a solid cam, open headers and free flowing intake on drag radials run a high 11 sec quarter. I have also seen a "cloned" Road Runner that popped his hood to find a 318 2 bbl, because it was really a Satellite (sp?) in Road Runner clothing. Unless you know what he's really got, you have no idea if he will spank you or not. Chances are, unless he has some MAJOR meat on the back, he will never hook up anything serious enough to move a tank like that anyway. Go for it.

Here is a neat link I found regarding the 68 S/S Barracuda

 

havent looked at the sites but i thought in 67 the ugly style fish had a few hemis stuff underneath them.

 

It's funny when people just say mid-12's or something like that for musclecars back then, especially when almost nothing aside from a ZL1 Camaro, certain HEMI's and the like ever touched that area, not even LS6 Chevelles. Most musclecars were 14 second cars, a few 15's, some 13's, and barely any 12's. All of which was incredible for the time. Sure better tires would have helped, but then we could also say that Third Gens could have tested faster and handled even better if they were tested with todays performance tire technology. A car tests the way it does for the time it's in and improvements like that do help, but the 60's/70's are also thought of as a time where companys or even magazines purposely tested ringers. It's pretty unheard of today but crazy times and such still happen.

And for the record, no factory musclecar (not sportscar like the Corvette and such) in street trim ever touched a ZL1 COPO Camaro. S/S Mopars were full-out real race cars from front to back, a ZL1 was a race engine in a regular production Camaro, like regular 426 HEMI cars. Not the same thing as you just can't compare the two. Also, ratings in the 60's were not accurate like they are these days. They were said to have more power than they actually had because of how they went about dynoing them, although there were exceptions like the Z28's, ZL1's, etc., which were actually rated at less than what they really had.

 

Yes, good points man. Back then, tires sucked real badly compared to now....that is why if you took a stock car from then and slapped a set of good sticky tires from now, theyd hook great and pull serious numbers. BTW, on the HP/TQ numbers being accurate I do have to say that there is one car that comes to mind with unaccurate numbers...LS6 70 SS Chevelle. GM printed this car made 450 HP and 500 lbs/Torque.......Car Craft or Hot Rod or some magazine bought one and took it from dealer to Dyno and it pulled a VERY impressive 518HP and 538 lbs/TQ.....If that doesnt impress you, then I dont know what will because if a car rolls from the factory like that, thats some mean stuff. Now i know their ways of testing then were a bit off compared to now but still, anything STOCK dynoing that, isnt a joke at all.....sad they couldnt make tires that could actually plant it.

 

Yup, Chevy usually underrated. They have even done it in these times.

 

well what did the l88 vette do i wouldnt mind one of those. and besides im sure some of the gt500s or boss 429s where pretty damn quick. i think the nicky maro with slicks was in the deep 12s and what about the motion vegas stage 3 mid 11s our vega will def do mid 11s when im done with it

 

Mid 13's for the first 3 cars you mentioned. The others were aftermarket conversions and not factory.

Don't know if this helps....

I've got a few buddys into Mopars...

One has a '69 Roadrunner, 440, mild cam, intake, worked carb, headers, and that's about it. With the 4 speed and the 3.3xx gears and drag radials he runs pretty consistent LOW 13's. And I can't stress how mild the build is...it runs on pump gas...and idles pretty smooth...

Another guy in his group runs a '70 GTX clone... It's a 440 car, but it's got a pretty nasty cam, intake, carb, headers, and an auto with a higher than stock stall converter. And I'm pretty sure it's got a bit more gear as well. It has run low 12's with drag radials....


I love alot of the Mopars...but it's not fair to race 'em...they get FASTER as they get older....all that metal eaten away by rust makes 'em lighter

 

uuuuuuuuuunnnnnnnnnuuuhhhhhhhhh nickey wasnt a aftermarket conversion it came off the show room floor like that so therefore it is factory

 

No... it was converted by the Nickey dealership. Not Factory.

 

Thanks. Same for Yenko and all the other various musclecars with performance company names or dealer owner names attatched to them. Sure Mopars get faster as the years go on, all musclecars do! That is simply because almost no one keeps them stock. It's especially difficult for Mopars as stock parts are incredibly difficult to find for them, and when they do, they are really expensive!

 

Actually, the Boss 429 mustangs weren't built by Ford, they were built by Kar Kraft, because Ford couldn't make the "semi hemi" 429 fit into the Mustang chassis, lol.

The GT500 was quite fast if it had a 427, but the 428 cars were more 'torque' engines than 'horsepower engines', sorta like the 455 Poncho Firebirds were... they topped out really easy. The 427 cars were crazy fast though.

The L88 Corvette WAS a race car. It was never a street car. That engine could run on no less than 103 octane leaded fuel because it had a 13:1 CR. The cam in that thing was a beast too. It wasn't streetable at all. I don't know the specs on that cam, but I do know that it couldn't idle below 1200rpm and stay running, and thats when it was up at running temperature! The L88 was a VERY hot running engine too... impossible to drive at legal speeds because of that. It just couldn't 'keep its cool' on the street.

BUT... If you could uncork an L88 and keep traction, it would just run away from litterally everything else made back then except maybe Chrysler's 13:1 CR race Hemi in the Dodge Dart. That would be close, but the L88 would still probably be faster. They ran mid 14s stock, but if you put a set of slicks on your 'Vette, it turned into a low 11 second car. That option doubled the price of a regular 427 Corvette though. The L88 option was around $3000 or so.

 

what about the v8 monza

 

Just curious where you got the info on the L88 Vette? Sure it needed high octane gas...but remember what period of time we're talking about...almost every gas station carried LEADED gas with that kind of Octane...not to mention gas was cheap...


Only reason I ask...the "old fart" who taught me alot of what I know about cars when I was young...well he happened to have a complete L88 Vette engine installed in his Chevelle. He even had the original sticker / emblem that came inside the L88 Vettes..mounted on the glovebox...

WARNING: Vehicle must operate on fuel having a minimum of 103 research octane and 95 motor octane or engine damage may result."

Also the compression ratio was 12.5:1 in 67,68 and early '69 and and it dropped to 12:1 in the mid to late 69 and later engines...

Not trying to be nitpicky just giving the specs...

And he drove that Chevelle ALOT....

The alum heads along with the long duration cam handled the higher compression ratio pretty well in my opinion...

As far as the cam...it was a solid cam...and the duration was low 300's....330-ish if I remember correctly...and it idled....

Granted it had a pretty nasty lope....and the idle was more of a swing from about 750rpm to about 1100 rpm.....but it would idle like that without stalling...

But to be honest back when I was a kid there were alot of cars with nasty cams that idled like that....


It is really comparing apples to oranges.... because in my opinion, unless more than say 1500-2000 of the cars were produced and sold in a model year run, than I, personally, don't consider it a "true" production car.



Just my 2 cents

 

my dad's coworker has a rebuilt chevelle built to '70 specs. He adds a lead treatment to the gas so he can run it.

thats all i know on the subject. LOL

 

LOL

 

never heard of that z28. but i do know they made more than 1500 v8 monzas

 

There is a good website about corvettes that has a lot of articles on different years: www.corvettearchive.com . Go to the section marked 1968-1982 and you can find some articles on the L88.

 

With a 262, they are pieces.

 

Or as I like to say, a turd.

 

i ont know some v8 monzas where quick you could do a copo order for any of the sb maybe bb
