Some interesting facts and nice to know..
Was speaking with some engine builders regarding the tuning of the barchetta engine and he told me that the early engines were preety good and one of the best fiat twin cams. The pistons are forged and with some lightening, balancing of the bottom end, cylinder head worked on, ie; ported and gas flowed correctly can produce power upto 250bhp..
Obviously this takes time and is costly but will be something i,m saving for and at some point have done to my barchetta...

For those with the later production models the block is different and the pistons standard.. Not so good.. !!
