Working on the wagon..

[EdontheBeach]

Jack - is it a stock type set up for the exhaust or true dual from the manifolds back? I have duals in the elky, i can't see ehere i have space to mount two mufflers with the floor depression my wagon has. and i don't like the stock arrangement, it's in the way too much.

Ed,
Mine are true duals from the headers back. 2.25" pipe with a pair of Walker universal replacement mufflers. I had Turbo muffs on it before, but had them removed because I didn't like the drone they produced.
Before that with my stock 305, I had the stock single pipe with a diesel dual outlet transverse muffler out back.

The mufflers are mounted further back under the rear floor with the pipes almost hugging the driveshaft. They're roughly 18" in length.
I guess the floor pan would be different between a wagon and an Elky. I also cut and welded a notch in the right side cross member. This was long before dual exhaust cross members were available for our cars. I have an Iceman double hump unit for when I put a 200-4R trans in the car.

I think the floor plans are the same. The floor pan is the same and where the raised section is for the rear seat in a sedan and wagon that's where the box starts on the El Camino......

off topic, Jack, I read about a young 11 yo boy getting bit by a diamondback rattlesnake in Gainsville, I didn't know you'd find that breed of snake in your area of Florida...

diamondbacks are all over the place down here in FL

Steve,
I saw the article in the Sunday paper. That poor kid received something like 40 vials of anti-venom and has been in the hospital for like a week so far.

BTW, you're absolutely right about the El Camino floorpan . It's kinda deceptive with the bed starting right behind the cab. It presents the illusion of a shorter floor pan.

but without the dip for the rear seats you have a good place to put 2 muflers, like i have in my elky - i don't have that in my wagon

Jack,

Is your exhaust something like this? This is what I've been trying to figure out on my heap. I want the exhaust as close to the floor as it can be without banging on the floor. Other than the tips, I'm of the opinion exhaust should be heard and not seen. Been trying to decide how I'm going to accommodate that. That's why I'm not installing the insulation on the floor until I figure out the brackets.

Did you purchase or have made your current system? You've got the slant cuts right on your tailpipes. I swear this is becoming a lost art. Gonna go out on a limb and say ninety percent of the people in Arizona have the pipes coming out under the rear bumper. Another thing we agree on is tailpipe exit behind the rear wheel just like the General would do it. ...

Every time I see your car I see my car with it's last paint job with one exception, yours is much nicer!

Scott,
Your exhaust system is laid out pretty much like mine, only yours appears to have been done nicer. Were you thinking of adding additional brackets to hold the pipes up? I'd have to look at mine again. I haven't been under the car in some time, aside from bolting and unbolting my bumpers.
I also like the pipes exiting behind the rear wheels. Although it does look good exiting out below the bumper. But I hear wagons are more susceptible to exhaust fumes entering thru the rear hatch of the car.
My exhaust system was done more than 20 yrs ago, believe it or not. When I lived in NY, most shops at the time did not want to do duals. I think it had something to do with compliance at the time. No catalytic convertors, plus not being able to pass inspection.
They did the bologna cut at the ends, but I added tips to exit out further past the body.

Wow!! Your car looked very much like mine, especially with the SS airdam...and being all white. My last paint job was a Maaco special. It looked pretty good for a number of years until the paint started flaking and going dead. I also had a few rust areas that needed attention...including my doors, fenders, rad support.

That's not my exhaust Jack, it's just a template I'm thinking I will build to. My only real modification would be an additional hanger utilizing the reinforced space where the seat belt fasteners come through the body floor. Man, you did real good if you've got a twenty year old exhaust system! Is that what the angle cut is called, a bologna cut? Learn something new every day.

If you look close on my old car you'll see a cowl induction hood. That's not a hood you could buy when I did the car up the first time. I had my body guy at the time cut up an old cowl induction hood from a 70 SS Chevelle and graphed it to the Malibu hood. It's a little heavy and probably won't make the show this time around but when it was first finished, there wasn't another one anywhere. Thought I had the "Bee's Knees" back then. ... :arrow: :arrow: :arrow: :shock:

Scott,
For the exhaust system lasting that many years, the car had been a daily driver for about that long. So the system never really built up condensation, or moisture. Even my headers are that old. They do need to be blasted and recoated (painted).
The term "bologna cut" was a term that I heard many years ago referring to an angle cut, as you referred to it as.

I didn't notice the cowl induction hood on your wagon in the older pic. Is it a completely functional cowl induction hood with air induction plenum?
You're right, the Goodmark or other brand cowl hoods were made later and weren't available for quite a while. Back before they were produced, I always thought how cool the car would look with a cowl induction hood like the Chevelle SS's and 1st generation Camaros.
I'm sure you received many complements and inquiries regarding your cowl induction hood at the time.
