There's nothing hard about making a flat crank V8.
TVR did it with the Cerbera, pretty much all race engines have them, Ferrari make them as standard in their V8...you just pop over to Farndon and them a pile of cash and they make one for you.

The only problem they don't sound even remotely like a normal V8, they pick up revs like crazy and they're not known for being particularly smooth!
Being as a Stag is already produced as a slant4, then the basic building blocks are all there.

I'm not sure if the LH cam from the TR7 drops directly into the RH stag head, so I would have to check on that....
Then of course you would have to reroute the entire inlet manifold because the firing/intake order would be evenly spaced rather than warble warble you get on a classic V8 cos of the 2 pistons firing consecutively on the same banks you normally get...
Then of course the main bearing loads would be totally different also....

So, now the only thing I need to figure out is what the correct euro millions lotto numbers are this weekend and then things will no doubt fall into place... Nevertheless it sure would be a fascinating project if we'd have a big enough budget.

Well I have no doubt some day, someone will make a steel crank for one of these engines, because the limited supply of old knackered severely underground ones is getting that way.
Also btw, bear in mind although the Stag crank is remarkably thin and spindly a single plane crank is even more so......like 1/3 off the weight.
If you bear in mind chinese steel rods now cost peanuts (tho not my cup of tea) and the need for decent pistons is an elephant in the room...sooner or later the value of a Stag topping 35-40k is going to make a steel engine frankly just a drop in the ocean.
Like do you know how much it is for a maserati-Cit SM, and they are horrible over-rated junk.

Have you seen the price of a TR5 recently, a Jaguar Mk2 or an E type?
Price of an engine rebuild???

They are all quite inferior vehicles compared with that beautiful cabrio from Coventry.

Give me a choice, which would I want to own?
NO WAY could you pay me to own one of those 60s or 70s Jags.

Sound suprised?
Well I get to drive them after they have had an engine change,- usually delivery back to the owner.
I remember the experience to this day, - blasting through the french mountains, while my mate in his Golf GTi 16V struggled to keep up.

The V12 E with all the ghastly rubbish that went wrong I would rather forget.
I have never understood the fascination for any of that dreadful unreliable Coventry 6 cylinder rubbish knocked out between 1967-1977 from Brown's lane.

Why i need a rolling road ( to set this thing up ) https://www.youtube.com/watch?v=GMrR9cwp49c

Dont worry down_the_plug_hole there will be no exaggerated or fantasize power readings max power is a standard 145 bhp, no more, no less, honest.

You need a Schenk or Heenan Froude, not a rolling road.
Doing things properly can't be achieved on a rolling road with a turbo car.

Anyone that does modified turbo cars would immediately tell you that.
Eg. Go see Ric Wood.

Look at the lovely Cosworth GAA he did.

is that Ric Woods "ROLLING ROAD TUNING" (http://www.ricwood.com/rollingroad.html)

I do have a background in electronics, so I know how they work and the problems inherent in eddy current effects v temp.
When was the last time you saw the fancy speel & marketing crap on a web site as ever reflecting reality?

Following disclaimers apply.
" A tuning session can take anything up to several days of effort".....

Btw have you ever owned a rolling road?
I have.
The brake is a truck TELMA (A French company) no matter what the fancy computerised claims may make of it.
Nothing has changed in 40 years.

Smartphone generation/you tuber generation and all that.
