Basically the 'Euro' Spec 1300 but combining the early euro cam with the later combustion chamber style cylinder head. Add in a bump to the static compression ratio with the Mondial Pistons and improve the breathing with a fully tuneable 36DCNVA carb...it's now well above the stock 1300's 75hp rating...2 kits available.
1 x New in the box OE 1300 Euro cylinder head. Complete fitted with new OE valves, springs, collets, retainers, springs seats, spring shim (x 8) Fiat part number 5881861. 36/31 valve sizes

Hi Compression Pistons are available separately.
OEM Mondial brand piston sets, 35.3mm Compression Height and have a 1.6mm raised dome. 86.8 and 87.0 oversizes only. Set of 4 pistons, rings, pins and clips.
Also available in 86.4mm (std for 1500 or 0.4mm oversize for early 1300)
Theoretical static CR in a 1500.
A basic compression ratio calculation looks like this:
Volume at BDC is (swept volume - pop up volume - dome )+ flycut volume + ring land clearance volume + gasket volume + chamber volume.
Volume at TDC is (volume in gasket - pop up - dome) + flycut volume + ring land clearance volume + chamber volume.
Volume of BDC over Volume at TDC is expressed as a ratio to one (xx:1)
Assume bore is 87.00
These Pistons are 86.50 above the top ring land and the top ring groove is 9mm down from the crown.
The Valve Flycut volume is approx 1.0cc
The Piston sits at approx 0.3mm plus deck
The dome is 1.6mm high, has a diameter of 70mm, and is 35mm wide (half a circle)
The Nominal Combustion Chamber volume is 33cc (euro 1500 carb)
Your head gasket is going to be 1.5mm compressed and has an inside fire ring diameter of 87.2mm (Fel-pro) and will give a SQ clearance of 1.2mm
So let's do some math...
Swept Volume of the cylinder.
Pi x R squared x Stroke
3.14285 x (43.5 x 43.5) x 63.9
3.14285 x 1892.25 x 63.9
380.017cc
Volume of the piston 'pop up'
3.14285 x (43.25 x 43.25) x 0.3
3.14285 x 1870.5625 x 0.3
1.765cc
Volume of the dome.
[3.14285 x (35 x 35) x 1.6] / 2
[3.14285 x 1225 x 1.6] / 2
3.08cc
Volume of the head gasket.
3.14285 x (43.6 x 43.6) x 1.5
3.14285 x 1900.96 x 1.5
8.96cc
Volume of the ring land clearance.
[3.14285 x (43.5 x 43.5) x 9] - [3.14285 x (43.25 x 43.25) x 9]
[3.14285 x 1892.25 x 9] - [3.14285 x 1870.5625 x 9]
53.62cc - 52.91cc
0.71cc
and then put these numbers into the equation,
Volume at BDC = (380.017 - 1.765 - 3.08) + 1 + 0.71 + 8.96 + 33
= 418.995
Volume at TDC = (8.96 - 1.765 - 3.08) + 1 + 0.71 + 33
= 38.825
V at BDC / V at TDC = 10.8:1 (10.79)
If fitted to a North American Spec engine with the 1.5mm full circular decompression recess in the head, we substitute the 33cc chamber volume for 38cc, so simply add 5 cc to the BDC/TDC volumes
423.995 / 43.825 = 9.67:1 with absolutely no changes to the cylinder head, up from the standard 8.5:1.
Even higher if you substitute a thinner head gasket (1.2 crushed = 1.79cc less volume)
422.205 / 42.035 = 10.04:1
That's 10:1 with no other changes... no block decking, no head skimming, no loss of belt tension, no cam timing issues.

and then put these numbers into the equation,

= 367.035
Volume at TDC = (7.17 - 1.765 - 3.08) + 1 + 0.71 + 33
= 36.955
V at BDC / V at TDC = 9.9:1
These are NOS but obsolete stock, and this style of piston is no longer made.
Once sold out, that's it, no more available.
Limited quantity. $500au plus postage per set.
Brand new Tipo style heads. (14 bolt)
Fitted with LPG compatible valve seat inserts and cast iron guides. 39.5mm inlet valve size, 35.5mm seat throat size. 31.0mm exhaust valve head size, 27.0mm exhaust seat throat size. Inlet port size 28.5/29.0 and exhaust port size 27.5mm.
I've flow tested one and the results were pretty good for a straight out of the box head. Figures are at 28" of H2O

Port air speed numbers were good as well. I've only taken measurements at 200thou and 400thou, but my flow bench plots a port speed profile across 9 points (8 points around the circumference and one right in the centre) using a pitot tube. At 200thou the 9 points range between 249 and 261 feet/sec, at 400thou the range is between 317 and 335 feet/sec...which is very good for an untouched port.
Now these numbers are with "as supplied" seat cuts, nothing fancy...so some improvement could be had simply by altering the seat cut to a narrower sealing face, at the moment they're almost 3mm wide. Same with the valves I used for the flow test, straight out of the box TRW replacement valves, no backcut or profiling, so these are totally raw figures and my baseline for these heads.
The 14 bolt Tipo type heads can fit the stock x19 10 bolt block, after the four small holes are plugged, and the thermostat has an adaptor plate to allow fitment of the stock X19 thermostat housing. Bare cylinder head as shown $750au plus postage. Limited quantity.
I can also offer these as a complete modified head. Ported, oversized exhaust seat fitted, new modified TRW 39.5/33.5 valves, bronze guides, flow tested, modified combustion chambers, valve springs to suit your application. All new custom built head to suit your engine requirements. 140CFM inlet flow up to 160CFM inlet flow at 340FPS air speed.
Single DCNF manifolds
Bare manifolds modified to suit a single DCNF style carburettor, two manifolds available Euro 1300 type. Correct angle for an X19 so the carburettor will sit vertical. Limited quantity, bare manifolds $250au plus postage. LAST TWO AVAILABLE.
