My 70 Mod project
« on: April 14, 2009, 04:39:31 PM »
This has turned out to be a long and arduous process.
The idea is to build a 70 jackshaft Panther into a tripple Hirth Mod

This is/was a 793 Hirth, it now sports 3- 650 fan cooled cylinders and heads,
current displacement is 975 cc
Three large miks to feed the beast.

Great project. What Mikunis did you decide on?

It looks like you did not have to spend to much on the donor chassis? hea...d hurts

I have lots of parts for the 70 panthers and the hirth. If you need something, let me know and I will try to help you out.
