You can make a whole car Fred! Nice Ha Ha. ;-)

Thank you Toon. I try to make one!!!hahhahahaha.

And some news about the engine. Not great news, because after fitting in the crankshaft an de pistons the block was not straight.
The formel owner machined the block, but with a difference of 0,15mm between the 1st and the 4th cilinder.
So everything out and the block will be machined again in my friends workshop.

Meanwhile I'm busy with the cilinderhead number 2. The original one was also machined, but also the valve were done!!??
And the intake was allready done and not fitting oké with my intake manifold.
I have another one and that one I'm going to use. Only one valve guide is broken, so I will replace al valve guides.
I also machined the cilinderhead because there are casting problems in the watercooling system. I cut them away so the water can go better into the cilinderhead.
After blasting(glass) the cilinderhead I just start with making the intake of the head fit well to the intake manifold I've got.

Cut away some aluminium and make it smooth with some fine tools
Then the intake manifold and the intake together with the gasket and do it again, until I've got a nice complete intake without any "bumps" or whatever!!
I also took out the valve guide.

The oilpump is ready and allready installed. Some modifications at the pick-up. Made the small opening a bit wider.
The plate were the gears are leaning on was a bit worn out, but with a diamond sanding block it all went well to make it smooth again.

Made from the old original timing gears, ajustable timing gears.

Also futher with the cilinderhead. After doing the seats with the B&D the seat must work after with some other tools.
All kinds of mills to make the 3 different angles in the intake seat. These angles are 30 degrees, 45 degrees and 70 degrees!
The valves are all fit in perfectly and the cilinderhead is also straight after a treatment on the millingmachine.

By using other camshafts I needed to machine the camshafthousing so after this the new camshaft can attack the valves in full order!!!

Hi Fred,
Did you ever consider the 16v head for more power? Original Abarth engines were quite powerful!
Thanks for the posts (and Maiden!)

Cheers,
Toby

Hello Toby,

Yes, I've thought about it, but first I want build this engine and maybe in the near future a 16v cilinderhead.
Hopefully I will get around 150bhp out of this engine.

Next month there will be two new "maiden"!!

Groet,
Fred

With the dry-build there are some other things that needed a good solution. The original mounting of the dynamo was to high so I needed another mounting bracket. These engines are being used in a lot of other Fiat models. The solution was the bracket of the Fiat 124 spider. Now the dynamo is much lower so I don't have a problem with the weber carbs.

In the meantime also made the steeringwheel. When I visit Engelbert Moell in 2009 I saw some steeringwheels at his museum.
There was also a Nardi wheel that was used in an Abarth. So I bought a Nardi wheel and found a horn with Abarth emblem at Ebay.
But they didn't fit. I had to make an adapter that fit on the Nardi wheel and were the horn also fit in.
Some machining and it fit.

Oh, and the tyres are here for the OT. Original Dunlop racings, 4.50 x 13 front and 5.25 x 13 rear.
