A big block chevy not including accessories is what, around 30-31” long and about 700 lbs. They sit about as far back as they can in these trucks. The Isuzu 6HK1 is 53” long and 1300 lbs. I’m not sure where you’ll find the extra 2 feet without getting really creative but by all means...

Maybe add another set of tires in the front to help with the extra weight!?

You must be registered for see images attach

That needs an 8ft mower under it. It'd be like a king sized Gravely.

What’s the Isuzu four cylinder ?
That’s in all the box trucks

Someone used to make a flywheel and motor mounts to put it in a Chevy

The 6 cylinder in question is gutless enough, I'd hate to drive one with 2 less cylinders.

I own one and although it would actual fit in the truck in question, it is indeed gutless. There seems to be no aftermarket tuners that offer box truck performance packages but maybe I just didn't google deeply enough? I learned a long time ago that the wheel doesn't need to be reinvented but not all of us got the memo.
