GM -v- Dodge head technology
ViperRay:
Your observation about an unforgiving track handling contributing to slower track times is a reality. Years ago, I borrowed a friends 84 Z51 Corvette and I was having a ball kicking the back end out going around corners. I have NEVER driven another...
I like Viper over Corvette, however, these Corvette issues really bug me:
Lighter, around 3100+
More Hp/Cu.In. (they have quench, we have.... what?... is there a name for it??? @#(*$&#*)
Hp/lb. engine weight is off the scale. Engine is 200-300 lbs lighter. (HaHa, could put LS7 in Viper...
That's just it. Poor Wayne paid people to work on it and to make a long story short, the hood/fascia gap outside the RHS headlight was almost TWO INCHES!!!!!!!
Almost 1/2 of that distortion was due to aft hoodpins that put the hood in longitudinal compression and trapeze lift springs that were...
Dean!
HaHa!
I'm getting packed to go back to PA. Have a lot of pics along the way, however, I HAD to post a nice final pic (this is NOT 'shopped - haha).
(Hoosier Daddy: Yes, this is Wayne's hood w/o any structural modifications. Yes, it is amazing. I still can't believe it.)
NOTE...
Well, I started bolting things down and working thru the fog hole is not bad. The only difficult headlight stud is the inner, forward one that goes to the frame bracket. You have to hold the nut with your 2nd and 3rd fingers to get it started.
One other item: Doing this method is the easy...
Tony,
HaHaHaaaaaaa
I've that that #*$&& fascia in my hands for hours and I never saw those slots!
I guess its because I've spent all my time laying up glass on the inside - haven't turned my attention to the outside yet.

Hemi,
So that's a...
Assembly CATCH-22.
When to bolt down the headlights? Before or after fascia install?
Frankly, it is difficult to snap the fascia over the RCP's with the bracket and brace loose. With the headlights bolted down it will be extremely difficult to accomplish.
I'm considering bolting the...
Hemi,
Yep I'm making shims. Local ralley car builder gave me some scrap plastic that appears to be exactly what Dodge uses.
I had to insert 7/16" additional shims, so my isolators are out of the hold.
Since this plastic is thermoplastic, I can heat and bend it, so I bent up a "shim box"...
Dean,
Do you mean make new isolation bumpers?
I cut a whole bunch of shims from the identical material (got lucky finding some). This stuff can be bent with heat so I was going to take the top shim and bend sides down to trap the lower shims. That only leaves securing fore/aft.
There is a...
Yeah Dean, my head is about to explode too!
FINALLY, I figured out what you were saying regarding bumper vertical adjustment!
It turnes out the pair of upper frame, forward facing stud pairs that the bumper adapter bracket attaches to - the studs that have the shim pack to adjust the...
I'm going to revise my understanding of the action of the 90deg bracket and the cross brace:
I was just playing around with the effects each of these have and I really have to say that the primary adjustment is a fore/aft of the outboard, top of the RCS (call it Location X). This is achieved...
GTS Dean,
Thanks for the detailed instructions. I'm dealing with a warped H'man "rigid" fascia that I actually cracked taking off - it is that hard to get over the RCS wheel well edges.
My head is spinning with all the possibilities, but I'm inserting my comments/concerns in your previous...
Need to buy a body sander and was wondering what the differences are.
I know of 2 types of pad motion:
1) I'll call one "translational" where the pad translates in a circular motion about a fixed point. The resulting diameter is maybe 1/4 inch. This action is usually found on square pad...
Am starting to slot the RCS horizontal bolt holes.
Came up with clever idea to produce a perfectly vertical slot: hang a 13/64" points and ignition wrench on the bolt. Gravity makes it hang vertically. Scribe both sides and you get a 1/4" wide, vertically, aligned slot.
Hoosier,
Are you sure about Nashville? I think I owned it back then.
Hemi,
Those frame shims below the radiator: There must be some kind of pin or bolt or something under the radiator because I can't slide them out. If I tug on one with pliers, I can see I'm pulling the RCS along with the...
Thanks AviP, I realized what you were talking about as soon as I got the fascia off.
Next question:
The horizontal bolts that fasten the RCS to the frame: Are the holes fixed or on sliding nut plates?
If they are fixed, I can use the bolt head for an approximate reference. If not, I will...
I'm looking at the raising the radiator core support (RCS) and am really mad that the shop manual does not include R&Ring this part. I have found 3 attachment points per side:
There is a bracket in the wheelwell that connects the RCS to the frame. 4 bolts, 2 on each leg of the 90 angle...
I'm also thinking of setting the back of the hood a little high due to desirable cooling effect of the resulting increased gap along bottom of windshield.
Also, pretty much decided to do the Archer (I think) fascia tap w/hood Dzus "latch" to tie down the hood/fascia @ outboard headlight. (Am...
Part of the investigation is to determine where the crack initiated. That will give a clue to the load that caused it.
Remember, crack propagation is a function of steady and unsteady stress.
Steady stress contributors are: gravity, fastener loads, engine torque and impulse loads.
Unsteady...
Thanks AviP, I'll post a pic when I get the fascia off.
Today I started taking all the lifting featherfill off the hood. A lot is coming off with a pressure washer.
(... prettu Ghetto, I know!)
Hemibeep,
The more I think about it, raising the core support will solve a lot of the problems. Are there any issues with the wheel wells when you do this?
Avip,
Could you please explain further your terms "Bumper Core" and "Bumper side frame (cross brace?)"
