TP seems to keep the details under wrap (as well as the car).
Randy Schultz had to widen his TR3 considerably to make the V8 fit so TP did well to get the V8 in it and as I recall Randy Schultz changed the chassis also. Plus 4
There is a TR3 V8 that often shows up the the "British Invasion" car show at Stowe Vt. I've spoken with the owner/builder several times but my aging brain has forgotten the details.
Just for the sake of conversation, and based on very little, I'd venture to guess that TP's car holds an old small block Ford. Based on even less, I'd guess that he used the transmission that came with the engine. Not even a guess at the rear axle.
(I wonder if he's already sold the Webers from the original car?)

Randy has a 4 cylinder in his car - he widened the chassis so he could fit the body on a later TR chassis with IRS. See > Randy Schultz's Triumph TR3 "Plus 4" Project, Part 1 <

The issue with sticking a V8 into a TR was always lack of room and people that ignorantly tossed out the front brace that held the suspension uprights apart because it got in the way (big mistake!).

I think I saw one with chev small block and a power glide 2 speed auto, but it has been many years. Around here (Seattle area) there are a number of Austin Healeys with V8s. I did notice on those they change the steering and have a U joint knuckle deal on the steering shaft. There should be enough of those to find some helpful information.

Did I watch the wrong video? I'm seeing a Miata engine (or at least a DOHC 4-cylinder with an ECU labeled "TR3/Miata Engine Computer").

The criss-cross pattern on the side of the head looks Miata-ish to me. That would also explain why they have a single 4-plug holder.

Having said that...
I'd hope anyone doing that kind of conversion would at least consider the Buick/Rover V8, since that engine eventually made its way into a Triumph.

The old style 215 isn't a very efficient engine. It produces middling power, unlike the modern versions from various Rovers. The packaging chore is easier on a 60 deg. V6 and power is comparable. I looked at both when swapping into an MGA and opted for the 3.4 V6 rather than the V8 (all I wanted was around 200 net bhp).

Billspohn, You are correct of course and the Nissan 4 probably out powers those period V8s.

It is too bad that the Triumph administration felt that they didn't want to continue the old BMC engines, as the later Rover versions of the V8 with PI were very decent. Instead they invented one of the worst V8 designs in memory, the Stag.

The Story of the Triumph Stag, the Car With Probably the Worst V8 Engine Ever

The Triumph Stag was a beautiful car, but unfortunately ruined by a very bad developed V8 engine. Here is the story of a failed 1970s car

There are a lot of nice Japanese engines that will fit into our cars. I had a '58 Big Healy in the early '80s with a 302 Chev Z28 motor and a 4 speed, it just burned tires up.
Now I've got a TR4 with a Honda S2000 engine that puts out around 250hp. It is a fairly low torque, but high revving engine so it feels just right
