1970 VS 71 Ralley Hood Question - 04/16/14 09:29 PM

When did the switch over occur for the 70 Cuda to 71 Cuda rally hood crush zones occur. It seems not many people selling hoods realize there is a difference between the years.

71 and up are all "crush' type design. '70 was solid up until January of '70 (I believe) and then switched over due to the feds changing the requirements for safety purposes.

So was the switch over the same for the Challenger? Jan 1970? The same for both plants Hamtramack/ LA?

I would like to hear from some owners of Rallye hooded Cudas, 1971 built pre Oct 1st.1970 on this subject. The 1970 Cudas style Shaker Hood with no crush zones was put on a lot of 1971 Cudas.

I have a Nov 69 built Cuda with a no crush hood, but I'm also restoring a 70 February build Cuda and want to verify it gets the crush zone hood

I think February '70 'Cuda "rallye hood" should NOT have CRUSH-ZONES. Anyone have one from February or March '70.

I have a 1971 383 Cuda rallye hood Nov.5,1970 build date and it has crush zones.I also have a 1971 Shaker Cuda that has the same Sched. build date and it has crush zones. I have never seen a Shaker hood with crush zones that was built in Nov or Dec. of 1970, the 1971 production year. That does not mean they are not out there.

I saw a June '70 built Challenger last weekend with a no crush zone hood. He said it was the original hood, but who knows for sure since he's not the original owner.

My 71 barracuda with a flat hood didn't have the crush zones. It was the original hood I am 100% positive. I don't know when my build date is though.

Your scheduled build date should be on the fender tag.

If things were running for Plymouth the same way they were running for Dodge, the date your car was built would likely be in June. Your Fender tag might say the end of May or the first week of June.

Re: 1970 VS 71 Ralley Hood Question - 04/19/14 05:49 PM

Maybe start a list on what hood is on your 70 or 71 Ebody and the build date for the car and crush zones or not.

1971 Challenger Convert. November 1970 door sticker A-20 on BC sheet, flat hood with crush zones.
1971 Challenger June 1971 door sticker May 24,71 on the fender tag, Shaker Hood with Crush Zones.
1971 Cuda Nov. 5th 1970 build date on the fender tag Shaker Hood with Crush zones.
1971 Cuda Nov. 5th 1970 build date on the fender tag Rallye Hood with Crush Zones.

Also have a Shaker hood off a May 1971 built car and it has crush zones and a Rallye hood that is a 1970 Model with NO crush zones and that I believe came off a Sept.1969 built Challenger.

my 05/26/71 built, vin#405093, 05/71 door sticker - shaker has the crush zones...

Re: 1970 VS 71 Ralley Hood Question - 04/20/14 01:52 PM

So is there any kind of a bulletin that was sent out making the change effective after Jan 1st of 70?

Posted By: hemicar1971

Re: 1970 VS 71 Ralley Hood Question - 04/20/14 04:19 PM

I have not seen any paper work on this Jan.1st.1970 date for any changes. There is paper work on when the Shaker Hood was to come back into production but I do not have that either.

Owners of 1970 E Bodies that were built between Oct.31, 1969 and the end of production in July 1970 would post the build date and the type of hood and if it has crush zones or not, then all might see a pattern. I say all E Bodies because I wonder if the same thing was going on with the Cuda as with the Challenger with ALL types of hoods and if any 1970 Cudas got the Crush Zone Hoods. There are early 1971 Shaker Hooded Cudas that have the None Crush Zone Shaker Hoods. This could be because of left over product from the 1970 build. Did all the Plymouths get the none crush zone hoods in early production, lets say before Oct.31 1970.

You would think that if this was a safety issue and the Gov. didn't want these no crush zone hoods installed there would be some sort of a paper trail to verify that they were no longer being installed.

Re: 1970 VS 71 Ralley Hood Question - 04/21/14 05:21 AM

I have a theory on why the Shaker Hood went out of production, but I have no proof, just a theory. Why did only the Shaker Hood go out of production and not the Rallye Hood and the Flat Hood, this backs up part of my theory on why the Shaker Hood went out of production for a while. Also I have serial numbers of five Challengers that received a Shaker Hood in the times that the Shaker Hoods were not put on Challengers. This was in Dec. and in Feb. When I wrote this information down I never even knew that the Shaker Hoods went out of production.

My SPD is also 203 so it looks like I'd be safe in finding a crush zone hood for mine.

As usual nothing ever makes sense with this E Body build over the first two years. Ola you have a Rallye Crush Zone Hood on your car, but when it comes to Cuda Shaker Hoods Chrysler used the NON Crush Zone Hoods well into the 1971 Production. I believe the Challenger Hoods were not changes to latter in the Year. It could also mean some got the crush zone hood in 1970 and Chrysler was using up the non crush zone stock for the Challenger. We would need many examples of Hood over each money the first two years of build to come up with some kind of pattern. I have also seen a April 1971 production date Hemi Cuda with a Shaker Hood and that car was said to be original paint and it had the NON crush zone Shaker Hood. Need lots and lots of people posting what their cars have for hoods.

That is one awesome looking Cuda Ola RED ON RED, wow.

ola`s the red/red/red man-awesome!!!

can anyone post a pic of a challenger shaker hood without crush zones-they would be early production and because the shaker wasn`t available at start of production-when were they introduced to the challenger?

my list of e bodies that i know
two nov 15th 69 cuda shakers-both no crush zones
march 70 challenger sports hood-crush zones
may 71 cuda shaker-crush zones.

Dont forget the "ba$tard" Challenger shaker hoods that were manufactured with a 70 top skin and the underside 71 style crush zones.
They may have been manufactured during the transition period over to the crush zones.
Most of them wound up at the Chrysler depots.
Hemicar1971 you should recall in 91 or 92 at Englishtown, Downer had 6 or 7 of these NOS hoods, and 2 of them went home with us.

Many years ago one 'theory' I heard on halting the 70 Challenger shaker hood production, and this is only speculation,... is that the underhood bracing broke loose, be it in accidents, or perhaps during crash tests.
That coupled with Ralph Nadar at the time crusading for saftey in the automobile industry, could have resulted in Chrysler rethinking their hood structure.

Agreed... Ola's red/red
