my engine will be based on the Z engine's crankcase which is iopen breather tower, i will use the stock 71mm crankshaft and 94mm pistons\liners and 2L rods my engine will also use an early 411 camshaft and 1800 heads (41X34) 2L stock carbs and t-1 cooling fan

now, please place your bets on the estimated HP on this one...
and i am ready to hear any advices before the project begins...

thank you :thumb

approx 2369cc and flies. he he he

I think it will be a lot closer to 1970cc.

Between 50-60 hp at the wheels.

What car is it going into? If it is going to have any sort of road handling find a 914 windage tray and fit it.

Fitting a type 1 fan how? What engine number is on the case? What is a Z engine?

Chris is right. 71mm crank and 94mm cylinders is precisely a stock 1970cc. They produced 70 bhp in Kombi form, with 7.3:1 compression. To get 2360cc you would need 103mm cylinders - a really nice modification.

Type 4 sedans had 1.7-litre engines from 1969 to 1973, with either 68 or 80 bhp depending on the model. The higher output engine had higher compression and fuel injection. A 'Z' engine is a 1.7-litre 68-bhp 411 engine used from 1970 to 1973 - the engine number had a Z prefix. The higher-spec 80-hp 1.7 used a 'W' engine number.

The last year of the Type 4 was 1974, when the engines were enlarged to 1.8 litres. The AT engine produced 75 hp, and the AN engine produced 85 hp. There were also two California smog engines, which had 76 hp (EC) and 80hp (EA).

The Type 4 sedan never had a 2-litre engine. Apart from Kombis, only the Porsche 914 did.

There aren't many of these blocks in Australia, as neither the 411/412 sedans or the Porsche 914 were sold here. 1800 Kombis had AP engine numbers, and 2-litre Kombis were mostly CJ or CV but you might find the occasional G for late fuel-injected pre'79 Kombis.
