I would be happy to contribute to the list suggested as i am an owner of two Pre War AC Cars which have the Weller engine.
Due to lack of good quality parts i have invested in tooling for the major engine components of this engine which have upgraded to offer longer life & potential performance, if you would be good enough to look at my web site '
www.ac-engine.com ' it gives an understanding of what i am doing & offering.
All the modifications & components are approved by the VSCC in UK & i am the only person with permission to use the AC logo on the blocks.
I expect to have all major engine castings by end this year, tooling made to AC Drawings plus upgrade.
Am not trying to use this site to advertise but just to explain what i am about. I fundimentally started due to my personal car needs.
Regards
Robin A Woolmer
