2056 engine questions, need to make decisions for restoration Options

[Type 47]

I need to decide what I'm doing engine wise with my 75' 2.0 resto. Cost is becoming an issue...without considering the engine my estimate so far is about $16k. That said I'm not going to do something just b/c it's cheap but I really don't want to go too much higher...

I have the 62k mile 2.0 sitting on the garage floor...it has 40 IDF Webers but has the stock cam...I don't think the case has ever been apart.

I also have a 73' 2.0 that I got at a swap meet about 15 years ago.

Should I just clean up the low mile original engine and put it back in?

Should I start from scratch and build the 73?

What caused the 75' to only have 88 HP vs. the 73's 95? The compression is the same.

Can I do something to the 75 to get it back the lost HP?

If I put the 75' back in should I put in a cam to work with the Webers?

What the heck are these things sticking out of the heads...they were not on any of the 5 other 914's I've had????

I would use the top end of the 73 to do a full rebuild of the 75 engine.

Check the 73 cylinders, have them bored to a 2056 or 96mm, get new cylinders and rings. have the crank, rods, heads rebuilt. Open up the valves on the heads and have them bore for the 2056. The crank should be good but the cam may need to be replaced. Maybe just reground. do all the usually upgrades, Type 1 oil pump, galley plugs, etc. and you should have a very low priced rebuild that will last you for a very good while.

Carbs are ok but you will get more HP with FI if you do it right. Carbs may get you low end torque but it isn't that much more than the factory FI and the FI will make it a sleeper. Not so much noise and better MPG for the HP.

Just my .02$

Oh and change the points to a optical or petronix. I prefer Crane but others use petronix
