Is a stock 1969 l71, 427ci, 435hp corvette faster then a stock 1971 429 scj mustang which I think has 375hp? On the video, move the curser over to 5:27, when he takes off!

There was a vette mag. that did a test on a stock BB vette and a stock GT 500 Shelby, they were very close.. that 375 hp. # might be a little low.. By the way , the Vette did win out.. ( i think that they were both 69's)

 

I think the vette would win.I have Mustangs,and they are respectable cars,but the 71 Boss 351 I had wouldn't hook up,and the 429 SCJ was a torque monster.
The 69 GT 500 would be a a 428 CJ engine in the Shelby.No 429 in 69/70 except the Boss 429.
\And yes,they were under rated.

 

20 years ago I had a '71 Mustang for some 8 years or so. This had 375 hp 429 SCJ C6 4.11 detroit locker. Was all 100% stock except for headers. Yes a torque monster indeed and very, very difficult to get traction. I had 295/50 Goodrich on rear end of mine and these would 'light up' without any provocation in 1st and 2nd ratios and even squeek the rubber going into top on a tarmac road. Can't say that the 4.11 rear helped inthis respect! Was it quicker than a 435 hp Vette? I can't say. Would it be quicker than my 4 speed 390 hp L36 Vette ? YES. The Vettes have vastly improved suspension and traction whereas the Mustang in stock form was total rubbish in this respect. I guess that any Vette driven by someone with adverage skills would be a good match against a 429 SCJ - with a skilled driver and a modified chassis etc hmmmmmm

 

I've got that mag around here somewhere but can't put my hands on it right now. If I recall, they were both 68's and the Vette ran the 1/4 mile in the mid 13's and was 3 or 4/10ths quicker than the Ford. The HP was probably about the same since most of Chevy's figures were overrated but the Vette's suspension, traction and lower weight made the difference.

 

In the early 1980's, there was a list generated (don't remember by whom) of the top 10 fastest American production cars ever built. Three of those were Corvettes....there wasn't a Mustang in the list.

 

Fords 375 hp for the 429 SCJ (like the 428 CJ before it) was either a very accurate 'real world' nett figure or at the worst a conservative rating at a time when most other US manufacturers were quoting gross or exaggerated figures.

 

I saw a list too,and it was in Hot Rod,or Car Craft,and the 70 LS6 Chevelle was first,then the 70 Hemi Cuda,and the 3rd was the 69 428CJ Mustang.There was vettes on there,but not the top 3.This was bone stock w/factory exhaust,and tires.

 

I don't know about the LS6 and all that, but Car and Driver or Road and Track (can't remember who) tested a new 66 427/425 L72 Corvette and with an M21, the stock skinny bias tires and an non-1/4 mile friendly 3.36 axle ratio, and it ran 12.8 at 112 mph bone stock and I think this is the quickest pure stock time for any normal production US car in the muscle car era. I've looked at a lot of road tests and most of the big boys were in the 13's, never seen anything run 12's stock. Not talking about the Hemi Dart, 427 Cobra or anything, just your normal production musclecar and don't think anything could touch a 66 L72. Do they have the times listed for the Chevelle and Cuda? I bet they are leaving the Vette out because it wasn't tested by them or they couldn't get their hands on one.

 

They did have the times listed,but not as low as the L72,if this was in showroom stock trim.I believe they were all in the ow 13s.I'm just sharing what I read,but no the LS6 Chevelle didn't pull a 12 off.

I dont know how many Ford lovers are out there but the 429`s in any configuration were dogs. It was for those heavy Lincolns and trucks. Bearing speed was there problem as the mains were gigantic. Nickelson and Shartman tried to make them work in there Funnies because they were on a Ford program and finally just gave up, the Chryslers were just too strong. Lesser HP 427 Vettes may have become victim's of a 429, but never as a solid lifter Vette engine. The Fords had to be extremely modified to come anywhere near the Vette in a drag race. Plus the 429`s were all hydraulic that was another bad comparison. No RPM`s. And the 428`s were not much better.........

 

Yeah, I hear you. I really think the guys at Car Craft, Hot Rod, etc didn't consider the Car and Driver and Road and Track guys to be that credible at the time and thought the test was bogus. That L72 was brutal and with the traction of the Vette off the line I would put it up against any of the others in pure stock trim. Where's Ironcross? I know he'll vouch for the L72!

EDIT: I knew he'd chime in!

 

I agree that you would have to do a lot of work on one to get the performance and reliability of a BBC, bu remember Chevys BB's had been around for some years and the 385 series engine was relatively new and as such never really developed properly. BTW 429 SCJ's in Mustangs were solid lifter. Interesting though that so much of the CJ 429's design was similar to the BBC's but just more of it - now if 500 + cu in stroker kits were so readilly and cheaply available 38 years ago !!!
