Update, as I found the previous owner of the car who mostly built it.
Engine block is lancia beta 2000
Head is Fiat Strada 105TC
Avanti fast road cams
Fiat Strada 105TC deep dome high compression pistons
I believe the head has had work done to it in addition to the fast road cams, because the power is high.
Fiat Strada 105TC gearbox with better gear ratios
0-60 in about 3.5secs
Top end unknown
1/4 mile unknown
160bhp with potential of 190bhp with big bore free flowing exhaust system, and good quality trumpets for the 40s
