JWF italia

JWF italia (Just Wanna Finnish)

original hot holden grey motor on singer 4a chassis

we were told it was a stock motor but when we pulled it down we found it had 3" 1/4 high compresion pistons worked cam, over sized valves and ported out head. all we had to do was new rings and this is what it sounds like......

These are photos of the work completed up close. Doors are re-hung, (made own hinges), Replaced all flooring, now is steel rather then before it was 5ply. It has taken quite a long time but i have made my own fiber glass bonnet, Made the molde myself, out of plaster. then filled with Fibreglass. Not Bad for Beginner. Now working on the engin bay.Still alot to go.... But starting to come together.

• These are some of the latest photos taken of the work and stages i have completed on the car...
  

it is fitted with a holden gray motor on a singer 9 chassi. it was bought in the early sixtys, and is belived to be last registered in S.A. purchesed from a lady who either lived in S.A and moved to V.I.C. Now the car has been in storage for about 43-44 years.

i think i have a jwf roadster but i am not sure, i need your help to confirm the actual make and model of the car.
