Pinto double spark plug head

Hello!

After a lot of thinking and preparation I have decided to modify Pinto EFi head to accept two spark plugs per cylinder.

This modificatio will allow me to use much higher cr and lose some pumping losses because combustion chambers after modification need some 23Deg BTDC of total ignition timing!

It is the fastest burn combustion chamber I have ever seen.

I could write a book about the modifications and how and why but for this introduction I'll be short.

I'll try to answer Your questions as detailed as possible if somebody wants to know something more about the mods...

Here are the pictures of the head:

Wow! You have some really interesting projects and they are alot more advanced than any other here on skogenracing.
