Hey All

I am kicking around a Greeves griffon 380 Rolling chassis missing the running gear.
I am also kicking around a T100 and T120 engine.
I have a faint idea that the T100 engine would be a good shoe in to the Greeves. I remember the old Challenger swaps, but this frame is much different. All tube and very very light. I assume it is either chromoly or really thin tube steel

Does anyone have experience with this?
Are the Greeves frames prone to cracking? If so where?

Much appreciated!

Here is a link to a Classic Motocross article that has the same machine with the optional leading link fork. Mine has the Ceriani fork in place
