ClassicCar

Recently I got from the USA a 1937 engine and gearbox( E- Bay )for my Brough Car.
The engine was rather cheap but transport to Holland and customs came on € 700.-
I was so lucky, the engine still have the original pistons.
This pistons I have removed with a lump of hardwood and a big hammer.
Finding +10 pistons is not so easy. The well known dealers from the HET-site started with +20.
A couple of months ago there was a discussion on the HET-site about oversizes and making pistons from bigger oversizes to fit.In general everybody agrees : try to use the smallest oversizes you can.
On E-Bay you can find someone who sells Hudson pistons.
But are these pistons the proper ones. I heard that the best are the ones with 4 rings. Two compression and two oilscapers.
Can someone help me to find the suitable +10 pistons for my engine?
The correct type and where I can get them.
Thank you in advance.
