    Flat hood-Shaker Conv Question
    « on: November 22, 2006 - 02:33:24 PM »
    OK, here is my final T.G. question.
    If i take a flat hood, buy a conversion kit.  Have it put together and put it on my Challenger....

    1 I will assume it will line up
    2 if I put a 383/440 in it should line up...?
    3 If I drop a 426 or Crate HEMI in ...It will line up?

    I would assume if you follow the instuction correctly it should line up, I can't see why not. :dunno:

    Yes, all 3 assumptions are correct (*see base plates below) regarding the conversion kits we sell anyway

    The bare hood & trim ring, bubble, adapter ring, air filter, air filter lid, bubble grills, hot& cold air doors, cables, etc. are all the same parts regardless of the engine.

     The ONLY items unique to each engine application are the base plates that sit on the carbs, there were unique bases for the Hemi, the 6 pack, and the 4 barrel engines (there were two styles for the 4 barrels from the factory, on fit the 383's and another fit both 340's and 440's). The Shaker "feet" are unique to each application but these are optional small parts. *On Base plates... New Crate Hemi's come with a single 4 barrel intake, there is no off the shelf base plate that I know of that fits it for a factory look when using the supplied 4 barrel intake, you'll need something custome there. But the hood hole location itself is correct for the Hemi application regardless of the intake chosen.

    Are there any aftermarket intakes that will line up the same? I know it is asking a lot but how about say a Performer RPM or Victor intake that can be used with a 383 or 440?

    No problem bringing Gene's name into the ring, I respect him as a competitor, he has nice product.

    I don't know if Gene Gregories (or Ben Snobars) single 4 base plates will fit a single 4 barrel Hemi Crate motor intake & carb setup, as far as I know they are made as stock replacments for the original 4 barrel setups. My guess is that their single 4 bases might work on the single 4 Crate Hemi's, or possibly will work after some minor tweaking. It's probably best to call them and ask them directly anyway.

     What you may be thinking of are the aftermarket DUAL 4 barrel bare plate setups that they sell, they are made to fit the Mopar Performance dual 4 barrel with two Holleys aftermarket but these intakes do not come on Crate Hemi's, they are sold sepperately. If you go that way FHO (For Hemi's Only) also sells a good Dual 4 base plate for the same application, you should shop all 3 vendors for the best price.

    My main point was that regardless of what intake and carb package you choose, the Shaker Hood scoop opening is the same for any of them so our Hood kits will give you the results you need no matter what combo you go with.

    It's not that the aftermarket intakes don't line up - they are usually too tall.  Had this problem with my 440 shaker conversion when I went to run a Performer RPM.  The regular Performer worked fine but the RPM was too tall.

    Exactly,

    Typically a base plate modification is required to drop the base plate down over the carbs to reduce the overall hight of the bubble so it will fit under the hood. The actual location of the hood hole opening is not an issue.

    This was my next question....making sure you get the proper height...whith all of those choices in intakes... sounds like you would need to pretty much by intake to hood for the application. :working:

    The shaker kits from Harms,Ben Snobar or George will all work with any engine as harms says its the base plate that needs attention.With the highrise aftermarket intakes you can modify a repop and drop it down over the carb.The factory aircleaner for a ralley hood hemi car was done this way,i sold one on e-bay last year,compard to the repops that do work it was a two peice stamping and then mated together in order to lower the height of the top plate,you can modify a repop and get the same results,you have to drop it about 3/4 to 1 inch to get the right clearence,also shakers look better when they are sitting up into the trim ring instead on an inch or so lower.

    I was sure I had seen diffeneces in the height of the shaker bubble, but not seeing them side by side makes pretty hard for a comparison.

    I thought it would look better sitting a bit higher...factory was lower?

    I would get a Weiand stealth before I get a Performer.  That choke well and EGR boss sure looks fugly!

    If you want to go to Performer RPM, only way is if you went EFI w/a super short throttle body.

    are there any advantages disaadvantages to these versions?

    Nothing ill towards HARM's  I am impressed with the look by all means but just curious as to the real differences, and any experiance with the styles.

    original looking, ease of instalation, cost, quality, etc.

    Here is a base plate I bought at a swap meet recently. It's an original Hemi Shaker Base plate that was butchered up for a custom intake of some kind or another. The cut and welded wall is about 1.25" in the front and tapers back to zero at the rear to accomodate the front to rear slope of the setup he used.

    A similar modification would be required  (to any factory base plate, 4BBL, Six Pack, Or Hemi) to allow for various aftermarket intake manifold styles.

    Due to the huge number of possible aftermarket combos there is no way to make one base plate that would accomodate all applications to put the Shaker bubble at the factory hieght through the hood opening.

    A couple popular Hemi intake/carb styles have been accomodated by a couple different vendors (mentioned above) who make special base plates for them, but otherwise one would be on his own to build something custom, especially with single 4 BBL applications.

    I won't "toot my own horn", these are just the facts. If you purchase one of our kits I will guarantee everything I'm claiming with a full money back refund if you are not happy, this includes shipping costs.

    1. We are the ONLY company reproducing an accurate Challenger under brace, Cuda's are different and all others on the market sell you the same Cuda piece when you buy their Challenger kit. Our stampings are unmatched in correct factory details; Ours have the correct overall die cut size and shape, correct crush wrinkles, correct slopes & radiuses on elevation changes, correctly sized stamped in overall contour shapes, and correctly sized and located drain and fixturing holes. All of these items are noticeably different as compared to any of our competitors.

    2. Our Trim rings are the most accurate offered by any kit manufacturer, they are clean, straight, don't vary in thickness, and are made of the correct zinc alloy material as originals were (all others are cast aluminum).

    3. Installation method is 100% your choice. I bought and converted one of my competitor’s kits using the supplied Vice Grip style flanging pliers (an item any Harbor Freight sells for about $20.00). While some think they work fine, IMO I found them to be inadequate for a professional job. So, we digitized an original Shaker Hood Trim Ring hood recess and made tooling which produces a stamped ring which you can weld or bond into your flat hood. This eliminates the need to hand form a flange, it's already pre-made for you. Should you decide that you'd rather use flanging pliers or another flange adding tool that's fine as well. Simply toss our supplied lip ring stamping and build a flange any way you like, our other parts work perfectly with EITHER method. The choice is entirely yours.

    4. We offer an instructional CD with our kits, lot's of helpful photos and details about getting it done right. If that fails to get you there you will also have my phone number, I'll gladly help you personally any time you like.

     :cheers:

    Scott
