Yes, it is Kwiek. It even says so on the rear trunk.
I talked to him ~1 year ago to do the same as I blew my 230 engine.
His approach was to use the NA M113 55 engine from a CL paired with the 722.x 5-speed automatic transmission.
Though at this time he has not done a Pagode. Now he has!
In the end though I went down the road of a 280 engine, freshly rebuilt by Metric Motors. It's just about done (should have it in a week or two).
