Wow! I think nowadays you'd put a modern turbocharged 6 with fuel injection and make massive power without the weight of a big V8 lump, but yeah, back in the 80's they were shoving V8's in all sorts of cars.
I picked up a zero turn "Troybilt" big ride on mower on Facebook with a blown up engine yesterday for the princely sum of 100 bucks. I was lucky to have been the first to see the ad on FB last week and by pure coincidence I've had a good engine sitting on my bench for the last year or so, so I contacted the seller and told him I'd take it.

today the "marriage" of mower and engine began. After sitting on my bum for the last 6 months it was great to get out into my filthy garage and make even more of a mess. I haven't finished it yet, but it will work.

It had a Husky engine in it, but I'm installing a 23 HP Briggs V Twin, so I've had to make a few mods to get everything to work. It has an electric clutch that is keyed onto the crankshaft, but the bolt that holds it all in is a long hardened metric bolt and of course the thread in the Briggs engine's crank is American Fine.

Luckily the metric bolt was about 1mm thicker than the bolt needed for the Briggs crank. I set the metric bolt up in my filthy lathe to turn it and used an angle grinder fitted with a flap disc to grind off the old thread.

Using a 7/16" NF button die, I cut a new thread on it, and it was good enough.

I fitted the pulley and the electric clutch, bolted it all up, and it was good.

OK, so I was almost ready to sit the engine on the mower, but I thought I better see if the engine mounting bolt holes were gonna line up, so I made a rough template of the engine's bolt holes on a piece of cardboard, and then transferred it to the mower, and was pleasantly surprised, that the holes were already there.

And so I lifted the engine off the bench, and carried it over to the mower.

Woohoo! OK, next was an exhaust system, All I had was the single cylinder husky header pipe, but I needed two, so I did some "cutting and shutting" to get me two pipes, which involved making another mounting flange. Once again, not pretty, but good enough.

That's as far as I got. It was cold and wet out today, I'd been out for 5 hours, and decided that was enough for the day. Hopefully it'll warm up a little during the week, and I'll do some more after work, there's not much grass to cut anyway, but by the time there is, I want to have it ready to do battle.
