Sheet Metal Quality
So, Project BABA YAGA! is waiting on several orders to arrive. In the interim, I am starting my due diligence for round two, when Body and Paint come into view.
I have a pristine replacement OEM hood that I got for $50 when I discovered the inner skin on my hood nose was cancerous. However, I am really being pulled toward the cowl induction hood. I guess my '69 Z/28 days still have a strong subliminal presence! Now, almost every vendor sells a functional cowl induction hood. This brings into play, the age old question as to which one(s) carry the good stuff and who carries crap. For instance, I looked at GMC Pauls and he carries the hood made by the same mfg. who makes Goodmark. He gets high praise and it sounds like a quality product. Top Banana, who seems to appear at the top of the list of a lot of quality questions, carries the hood and I have yet to hear back from them as to who manufactures it. The price differential between the two vendors is $124 delivered. That's substantial enough to question quality differences before purchasing. While I am waiting to hear back from Top Banana, can anyone shed any additional light on these vendors and or the product? I have had no dealings with either one and any comment is welcome. ------------------------------------ EDIT: Top Banana gets their parts from Key Parts in Virginia. They seem to have a great story. Anyone have any comparisons between them and the company that produces for Goodmark and GMC Pauls? Could it be Key Parts ships to both? Since you can't buy direct from Key Parts, it would be beneficial for the vendors to let people know who supplies their parts. What have they got to lose?

Re: Sheet Metal Quality
Got the Goodmark hood for both my 74 & 86. 86 fit better than the 74 but both were above average material thickness but nowhere close to OEM. Did you call and make sure it is a functional cowl hood? Both of mine did not have the round air cleaner hole in them.

Re: Sheet Metal Quality
Both GMC Pauls and Top Banana state they are fully functioning cowl induction hoods. What was off on your '74?

Re: Sheet Metal Quality
The 86 had better body gaps than the 74.

Re: Sheet Metal Quality
Wow... the gaps on these trucks are bad to start with, so that isn't saying much!
The '86 does look a sight better. Guess I will just have to weld the whole front end together and tilt it ala gasser style... Thanks!

Re: Sheet Metal Quality
Wow, Key Parts. Used to use them for cheap fixes when I had a body shop. Some times things were spot on, sometimes they were pretty bad. Luck of the draw it seemed.

![]() ![]() I could always get the steel '69 Z/28 induction part and weld it to my OEM hood and not mess with the whole gap and gauge issues associated with a repro aftermarket CI Hood. Given the cost to purchase, ship, repair and install the repro, I might even be money ahead. Besides, most of the repro CI Hoods do not have the correct '69 Z/28 lip on them anyway and that's 90% of the looks! Or leave it OEM... but that's not fun.

Re: Sheet Metal Quality
Scratch that, it was Keystone. If you do a search on their site it takes you to another site with a BUNCH of different hoods just to confuse you more.

Re: Sheet Metal Quality
If I were to do a custom hood look, I would do a shaker setup. I modified a 79 Monte Carlo hood on a build many years back using a mid 70's Pontiac hood and shaker assembly....it was definitely a killer look! I have another setup in storage and I've got my eye on a clean 81 2WD Shortbox that I'm debating pulling the trigger on only because I think a 454/TH400 equipped Shortbox with a shaker setup will flip people out!

Re: Sheet Metal Quality
I bought a CI Hood from GMG Paul about 5 yr's ago at auto fest in Charlotte NC. to replace my POS Harwood CI Hood. I still haven't installed it so I can't really comment on fitment. But I can tell you this, Other that it letting in or out a lot of air they defiantly are not functional unless it has the vacuum flap door and plenum that seals around the air cleaner.
That's not saying that they haven't changed 'em. But I myself have not seen a true functional cowl induction hood made for our truck's. |

Re: Sheet Metal Quality
I think I am partial to the Challenger Shaker Hood... I need to look into the design and see if I can laser cut the parts and weld up the basic shape. Then cut parts for the base using an air cleaner base as a pattern... With aftermarket and OEM's going for $1,800-$3,500... a knockoff is in order. I have a friend who has several containers full of vintage Chrysler parts... might be a good source for dimensions.

They dont need to be sealed to the air cleaner. The high pressure air is still getting forced into the engine bay, and putting a supply of fresh, clean air around the general area of the intake. As good as sealed? Nope. Still functional? Yup.

In the end, some functionality is good but the overall look is also important for my non-stock project. The '69 Z/28 or Challenger style Shaker are both strong candidates.

Re: Sheet Metal Quality
^^^^^ Right, a shaker that extended close to the windshield would be most ideal. But then it would just look like a cowl.
And of course looks are important.

Re: Sheet Metal Quality
The trucks can prolly get away with using the longer style shaker base cleaner from the later 70's-say 1977-later TA's. The 78-88 Gbodies can't use the later style because it would cut into the firewall area-by sight I think the trucks can get away with it tho.

I like the Challenger/'Cuda look with the front air intake and sealed over the carburetor.

I have the software, equipment and some expert welding help to design and fab one. I envision a three piece setup. The base unit on the carburetor, the lower half of the Shaker and the top half of the Shaker. I see the top half bolted to the lower half with SS Cap Screws. The base piece will use the same rubber weather seals that go on the doors. I really think a hybrid is very doable. The second option is me making a two piece mould and creating a fiberglass/carbon fiber Shaker. I can make the mould but have never used fiberglass cloth. Wouldn't be my first choice.

Re: Sheet Metal Quality
I got some keystone fenders on my 73, perfect no, thin yes but fit nice only one hole needed any reaming.
And I have a Harwood glass hood. Fit and finish is really decent.

Re: Sheet Metal Quality

Here's why..... The purpose of sealing the hood to the air cleaner is to keep the cooler dense high pressure air charge from mixing with that of the hot air within the confines of the engine compartment thus making more power. Furthermore the flap door isn't there to keep out water dirt and other debris it's actual function is to open at high demands of the engine or WOT typically when the vehicle is operating at higher rates of speed when the air pressure is high as well so when the flap opens the high pressure air takes the path of least resistance and the engine is also sucking the air in as well because it's at WOT. I hope that helps. |

Re: Sheet Metal Quality
All GM style cowl hoods have a solenoid which opens the flper door when manifold vacuum drops to a certain level (aka WOT for example) and let's a rush of cool air in creating a little more dense intake charge.
Anyway, a shaker is a more creative approach simply because it involves more work to get it right and you need good (actually-excellent!) fab skills to pull it off correctly. |

Re: Sheet Metal Quality
I need to find dimensions of the Challenger Shaker online or in my buddies stash... this experiment is too long. I need to knock off a few inches from the back but that's an easy fix.
I know we can model it up into components and make a prototype. It's late and I need to get away from the box for a few hours.
