Welding the plug-holes...(Plugs will be placed like the on Porsche 914 heads).

Some more welding

This is what I've done so far....hope to finish this engine before the summer season here in Norway...and make 200HP+ in the dyno

Hello,

Looks really nice but I notice two things that would worry me.
Why not welding the critical top fin above the sparkplug hole. You will really need that if you run large diameter cylinders in order to support and not ask for immediate leakage.
Furthermore, seems you have the seats installed prior to welding?
Or will you replace the seats for bronze or in any case replace them?
I would be afraid of introducing potential lose seats.
My preffered method is to have anything welded done first, then lastly do the final machining and shrink in the seats.

In any case, nice engine you got going. Will be nice.
Cam? Get one of Jakes split duration.

Hi, and thanks for your reply!

I'll do some more welding on these heads...
And the seats will be replaced

(I did not plan on welding the heads, that is why I got the seats installed before welding).

Thanks,
Geir

Nice job. I'm also planing to do some welding on mine heads soon. Spark relocation and some combustion mods in order to promote squish and rise the compression. Do you know the angle of the spark plug on the 914 GB heads? (compared to the horizontal or vertical plane of the heads)
Which filler rod did you use for welding? Thanks.

I will find out this stuff for you, but it won't be till after the 1st of the year.

Time for a little update....

Here I've "glassblasted" the engine case.

Here's the crank...a 78mm DPR.

5,6" CB Race rods.

Bought a cam from Kjell Aaen (Kvikk Service AS, Norway).

305 degrees, 14,50mm lift.

Lifters from Kjell Aaen...to the left

Engine case machined for "bigfoot" lifters...

Try to have the crank nitrated. IIRC, the come back from DPR very soft...

Nice lifters! What do they weigh? and what are they made of? (tool steel perhaps, like Udo Becks T1 lifters?)
