1973-76 Cowl induction vent mod on my 77 non vented hood.
This week I decided to do the hood on my Vette. I have always liked the Cowl induction vent that the 73-76s have but because of the changes to the inside structure of the hood after 76 , That meant that I would have to modify my own hood to get the look i am after.
I do not care about it being a working induction system so that makes the whole thing much much easier. I got ahold of a cowl hood from a guy that was damaged for a couple bucks with the vent grille and hood section undamaged.
Here is the procedure that I followed to graft the new piece on my hood.
This is the hood from my 77.
First I of course needed to strip the paint of my hood.
After stripping the hood I cut out my first opening from the bottom using the the hoods inner frame as a guide.
Ok.... So now here are the new pieces that I will use.
Grille.....
Opening...Trimmed and ready to go.
So I just simply layed the new piece on the hood and marked the hole with a sharpie....
I then started to cut out the marked section, Being careful not to cut through the hood bottom structure.
After prepping the two surfaces I used SMC panel adhesive to attach the panel to the hood.
I then lightly clamped the two together and let it all dry overnight.
Looks good so far...
I then turned the hood over so I can finish the underside of the transplant first. I have more to do under the hood in some other sections ,So I will leave this like this for now.
Blended right in and looks like it came that way..
I then turned my attention back to the top of the hood. I first finished stripping the last of the previous finish of the hood. Now whats left is to grind down the joints as if I were doing the fender joints. Then some VPA and the rest is just regular bodywork followed by three coats of Slicksand.
Next I will let this sit for a couple of days at that time I will finish the underside. Stay tuned.......
