This is a great thread!
When I think DPO it reminds me that my car was supposedly "set up" for autocross when I bought it. Hey, I was young and knew little more than squat about cars, and so just thought, "Cool!" (making me the DCO right off the bat).
Might say the DPO was a "budget racer"! Don't know how he got the car past any tech inspection anywhere.
There were "lowering blocks" under the TR4's rear axle, a pair of short pieces of 2x4. (Only the best, clear pine will do!) Thankfully, there are no termites at high altitude in Colorado. Had it been me, I would have at least spray painted the blocks black to sorta resemble metal. But these still had all their glorious wood grain showing through greasy fingerprints.
The front springs had each been "stiffened" with a few of those twist-in "spring savers" that used to be sold, instead of installing a actual sway bar or anything normal like that. The alu spring spacers had been removed to lower the front, but left the springs in danger of jumping off their perches when going over any sort of bump. Thankfully the Konis were there to keep the coils from completely escaping! At least I found the spacers rattling around in the trunk, when it came time to reinstall them.
The car came fitted with 14x7" wheels that tended to rub the tires inside the fenders on moderately hard corners, but certainly lowered it a bit more.
Highway cruisin' was miserable higher-rpm stuff even at 60-70 mph, thanks to those smaller wheels and low profile tires. But the car got up to speed very quickly! Turns out that was an old, cheap-racer trick... Get more acceleration with smaller wheels and low tires, instead of actually changing the axle ratio.
Actually the car cornered suprisingly well and would really accelerate, too.... If you could just overlook the cracking wood, rattling springs and rubbing tire noises.
I almost forgot, the DPO had painted the car a lovely "Porsche Orange", too. Predictibly, he bought a 914 shortly after selling the TR4 to me.
My opportunity to repaint came around fairly quickly, when I got rear-ended by an unlicensed, drunk driver in a full size pickup truck (I was stopped in a left turn lane waiting for traffic to clear. There were a total of 11 people, including 4-5 kids, in the P/U.)
That was also the moment when I found out the hard way that the PO's anchor point for the shoulder belt wasn't a very good idea. The bolt through the roll bar close behind the driver's head was more of an Aztec brain surgery tool, than part of any "safety" system.
His buddy also had a TR4 and autocrossed it. The buddy's Triumph had gnarly fiberglass fender flares all the way around, super wide tires and a serious flame paint job on the hood and front fenders. I expected to see a V8 stuffed into it, but it was still a good old TRactor motor.
If only he'd cut a hole in the hood with a saber saw and strapped a blower on top of the motor, it would have looked just like an Ed "Big Daddy" Roth drawing come to life! In fact, if I recall the buddy sorta resembled Rat Fink... But that was a lot of years ago and I met him only briefly, so maybe I'm thinking of someone else.
After waiting a full year for a local shop to find a manifold, I converted the car to use a pair of Weber DCOEs I'd picked up. Packed up the old carbs, put them in storage and forgot about them. It ended up being 20-25 years before I looked closely at the "original" carbs, and realized something was out of whack. Eventually, with some help of other folks, we identified them as Hitachi SUs off a Datsun 240Z. I'm sure there is an interesting story behind that, too.
Not that I'm any less a DCO! My "tuning" of the newly Webers was all trial and error stuff. Lucky I didn't blow up the engine.
I installed an exhaust header eventually, and worked out my own rather crude "free flow" exhaust system which included a Ford muffler and some mystery piping. Didn't have a bender so I simply cut and welded up a strangely angular fixture that found it's way to the back of the car. Way heavier than necessary, but was actually still quite solid when I took a cutting torch to it a few years ago.
The Ford muffler made for a somewhat weird exhaust note, which wasn't as bad as the loud "clank" the pipe always made inside the frame going over the slightest bump. Thought about tapping a few pine wood shims in around the pipe to stop that, but thankfully never got around to it.
Let's not talk about Bondo and my "rolling restoration", okay?
Managed to drive the car for ten years, adding a few more of my own special DCO touches here and there, before carefully storing the car away so my nephew's Rotweiller could curl up and sleep on the hood during cold Colorado winters.
