Hi

Its whole engine from Fabia 1.4 MPi (pushrod engine), - stiffer block in comparison to 1.3 in felicia, crank with 78mm stroke and bore 75,5mm like 1.3. Bottom end standart, but blueprinted and lightened. Camshafts 296/296 and 7,5mm lift..

Head is 1.3 MPi 50kW felicia, highly modified,carburetors Webers 40 or 45 acc. to what kind of race is planned... 40 are more torqier with better pedal feedback, but less power and lower redline - used for race on snow... estimated bhp with this spec. are about 125bhp

45 are used for road, circuit, rallye races... estimated power ver 140bhp.. estimation based on comparison with similar car

today I wake up very early and worked on engine for my tipo..
first few numbers:

piston weights: 375 to 376g
piston pin weight: 90g
rods -656x3+1x658g

piston to bore clearance 1,2,4 cyl 0,1mm; cyl. no. 3 0,08mm (factory values are 0,04-0,06; 0,1 is probably goog for intended use of engine)
piston rings eng gap matched to 0,30 top ring; 0,35 second... so in the lower range of factory specs. for that engine.

It looks like you did not use ARP connecting rod bolts on your engine build as you planned, what made you change your mind ?
