Combustion chamber CC's

[Dominic]

My father just bought a festival TTA and it has some engine issues, i'm in the process of rebuilding it for him and was wondering if anyone know what the factory combustion chamber volume on the head was? I am planning on cc'ing his heads because i think they have been surfaced a lot in the past, but would like to know the original volume to compare so i can get the compression right. Also.....Is there an off the shelf part # for a TTA forged piston? Ross? JE? Speed Pro?

thank's.

41 cc is what mine measured when they were stock.

Hi,
We need some feedback from the knowledgeable ones out there. Julio,what do you think about this? I can buy 41 cc, but don't know for sure.Maybe the info would be on gnttype.org...?

If you don't believe it why did you ask? Measure them yourself? :wink:

Hi,
No disrespect meant, I just thought some input about nominal values would be helpful. Good luck with your rebuild.
