Just pulled the engine out of the TR4 tonight. Feels like it has about 10 psi worth of compression (can spin it by hand - easily) and I have a spare bmw m42/trans engine harness, ecu... In the end, I think it's probably more expensive to get 170 hp out of the bmw engine than the TR motor, but the bmw is 140hp to plug in... maybe a bmw powered locost instead.
Body is about finished - with about 65 patches welded in - ughh.
I admire your patience in body work 
nice work
Bodywork looks good.
Plus I'm sure you can fit a 13B in there 
There is no blasphemy on this forum. 
Stick it in there and be sure to have a build thread. 
Bodywork looks good. I hate making and welding patch panels. Tedious, time consuming and invariably I'm overly optimistic about the thickness of the original panel and end up blowing a hole in it with the welder.
excellent patching there. Did the factory use saltwater as a primer?
After this one, I no longer fear rust. I have lots of hammers, anvils and a welder 
It would be nice to just build something without all the repair stuff.
yes but
I say do it. Classic style, modern drivability, what's not to like?
Do it.
Good intake and exhaust, chip, lightweight flywheel, Convert to coil on plugs............has seen ~130whp out an M42.
Cams and standalone may get you the rest of the way there. Of course, if you're insane, you can look for the stroker crank and overbored pistons and I think get 2100cc.

I'll just leave this here:
Even if Triumphs did have Massey Ferguson engines in them something always just feels wrong to me about a German engine in an English car. That said, if it works for you, do it. There is a TR6 with a BMW engine in it, so you wouldn't be treading in completely uncharted territory.
I tend to enjoy the masocshism that is trying get old English engine to make respectable horsepower.
Ha, I will put any engine into any car, if the combo appeals to me, so IMHO go for it mate.

Good head work is key if you want to keep the Triumph and get power out of it. There was an article in Classic Motorsports awhile back regarding reworking an MGB head and creating a 0-60-in-under-10-secs-machine. The article also stresses how a cam and carbs on that motor only made the "wide end of the funnel" wider and didn't address the restriction.
The company doing the work is listed in the article so they might discuss with you how to relieve your head (okay, not your head. The engine head).
I say go for it. I may be biased, but I think the M42/44 is a great little engine that is way overlooked because of the bigger M50 six cylinder engines. It may lack the trick variable valve stuff, two cylinders, and that awesome exhaust note, but it is a good lump.
Twin cams, 16valves, dual plane intake (on the later 42 and 44s), and it is quite revvy.. if not for the stock injection that BMW used to hobble it.
I know many people in the BMW circles disagree with me.. but BMW did hamstring the 4 cylinders in order to get people into the "better" Straight Six cars. There is no other reason for the larger m44 (1.9 vs 1.8) to have the EXACT same horsepower numbers even though the M44 is larger and uses a better and less restrictive system for measuring the air that goes into the car.

I'm surprised nobody mentioned that BMW currently owns the rights to the Triumph name, which might make this engine swap a bit more apropos.
As a previous poster pointed out, there is a TR6 that appeared not too long ago on BaT with a BMW 6 cylinder engine....so why not?
There's only about a dozen mg parts left in my mg
