Technical Flat head cam ?

What sort of cam can I put on my french flat head ?
It's put on my 46 coupe with original transmission and 3.78 for the rear axle On my engine I have intake three power with three 94's
Thank you for your help

 

hi bobo....i have a 255 french marmon flatehad,you have the 239? engine is ported?

 

It's a 255 and it's ported

 

Wow that's an open ended question.
With triples and ported a good sounding idle for a moderately heavy car an Isky 107b is a starting point. Though such an open ended question you will have a stream of suggestions.

 

Literio L100 or Isky 1007b or Schneider 254f

My opinion

 

Thank you for your answers which are the characteristics of the 1007 b I don't know it ,I like very much the 400jr and the Max1 but I had only 2 carbs

On my tree power the linkage is progressive !
