THINKING OF CONVERTING MY REGULAR 70RT HOOD TO A SHAKER I HAVE QUESTIONS

[kevs70charger]

I am thinking of changing my 70 R/T 440 car with Regular two bulge hood to a shaker it has a 4 barrel on it now, would like to have a Shaker.  Not too sure what all is needed, is there a conversation kit with all the parts, since my block is a 440 Six pack block already thinking of getting a six pack as well, or is there a shaker for a 4 barrel .  Thanks

Here's one place to look:

The shaker conversion is very expensive!

If you want a flat hood to do the conversion I can sell you one cheap!

How much does a conversation cost give or take ?

Yes there is 4bbl version.  Here is a sample of most parts

I hear the repro shaker hoods are not bad based on other owner reviews.  Could cost $4-5K for everything

We've discussed it here on converting a flat hood to a shaker a few times.
It's alot of hours to convert one into a shaker Hood. Ask me...I know. I did it.
I probably put close to 40 hours into it.

The main benefit is a stronger thicker metal gauge hood than what the repro's are pre made.

Your starting point to begin the cut is the very last rear edge closest to the hood cowl. It takes numerous measurements to make sure it's done right. The Challenger & Cuda distance may be different from each other.

Here it is painted.

That looks like the ultimate measure twice, cut once scenario    If I hadn't been able to find the metal TA scoop I was going to go with a shaker.

Firstly do not cut your Hood being 70 it may still have the original hood , 1 year only .
 I have a friend with a flat hood in Airdrie we saved as a possible shaker hood if needed it may be available .
budget 5k to do a shaker conversion , this includes a new hood & all the parts to make it work , I doubt you would save any $$ converting a flat hood .
 The Shaker hood on a Chall was a very rare option in 70 I do not have the numbers handy but 200 for the whole year or so . Second the Shaker was available as an option on Challengers , I know of a factory 383 4 bbl , so yes you could get 383, 440, 440+6 or Hemi & possibly 340 with a shaker hood .
 The Shaker is restrictive , the openings are small & tend to starve out 6 pack & Hemi engines , We did a whole dyno tune on a SS Hemi Cuda & tuned in a bunch of power then installed the shaker & had to retune way back down again , in SS you have to run the grilles in the scoop so we couldn't even leave those out .
 The suppliers I am aware of are Roseville , talk to Dave or Paul , they are awesome to deal with & offer discounts to members here .
 Also Gene Gregory in Alhambra ?

You have a rare U-code car.  I wouldn't put a more common Six-Pack on that car.

Yes, you can get a four-barrel base plate.  Be sure to get the right one.  440 is slightly diff. than a 383 and a bit more diff. than a 340 baseplate.

All the repop Shaker hoods are the '71-style crush zone style.

So if you want it correct looking, you can get a RestoRick.com Challenger shaker conversion like what Topcat has done, on a 1970 flat hood.  If you really want it done right, best to have a real shaker to work off of.  The spot welds are unique for sure.

I personally like the car the way it is.

I agree, IMO, to many shakers out there now. I like the double bump. But its your car.

The factory 70 Challenger shaker was very rare ....  maybe 100 originally .
 It is your car do what you like , just do not cut the hood you have up so you can return to stock .

Is the $900 Repro Shaker Hood pretty much plug and play or maybe not?

Are there any critical dimensions or tolerances of say back of engine to firewall distance, hood to engine clearance, etc, that you would have to check before diving into this project to see if it would even work?

I guess, how much tolerance (+ or -) is there in the x,y,z coordinates in 3 dimensions?
