Guess the piston.....

Post by 8541Hawk »

I did find something I thought was interesting once I had a VTR engine in bits. The pistons did remind me of some I had used in the past.
So here you go VTR pistons on the left but what did the one on the right come out of?

Lawn mower?
It's not falling off, it's an upgrade opportunity.

4000cc divide by 8 equals 500cc

well, it had 4 valves per cylinder and the valve cut-outs seem to indicate valves that are splayed apart quite a bit, like an old Honda Pentroof design (with a 60-degree spread angle), so I will go with an older big-bore Honda single, like an XL or XR 500.

You sir are correct.....Here is the states it is a common sight as it is a piston from a small block Chevrolet. In fact the one pictured is my door stop...lol
The 4 valve cut outs are so it can be run in either bank.
It is a 100mm piston and was used in 4 different displacements depending on the rod and crank combo. They were the 4 "performance" based engines which were the 302 ci or 5 liter, 327ci or 5.4 liter, 350ci or 5.7 liter and finally the 383ci or 6.3 liter
