I have my engine sitting where I like it. Angles are good; 2 degrees up then 2 degrees down to keep the jet input shaft and crankshaft parallel. Rails are level. I am using blocks with 4 degrees machined into them and sit flush to the rail and plate. My issue is that the plates are not sitting on the rail; 1/2 inch gap in rear and about 3/4 in the front. Will this work? ...... BBC, 496, Jacuzzi, 21 ft. Mini cruiser

I figured it out. I will flip the rails so the flat side is up an level to the stringers. Then cut the plates to sit on the rails and maintain my geometry.

And two degrees is a shitload... How long is the driveline? how much "pan room" do you have left?

The driveline is a standard 2 u joint split yoke kinda deal. What kind of angle works better? From the searching I have done, 2 degrees at each u joint seems good. 2 up and 2 down to get the crankshaft line parallel to jet input shaft. The blocks have 4 degrees machined into them from Tom at JBP. That would now put my rails level and the engine sitting 4 degrees up.... what am I missing???

Really only a degree or even get away with a half. The pump shaft angle should be at three degrees to the stringer, the crankshaft should be exactly the same, which you do have, so that means you should likely have a 1 degree down on the rails in the fron to eat up the last degree for the blocks...No?

Initially I did have 2 down, then 2 up, but info coming from you seems to be biblical around here so I went with your recommendation. 1 degree down from shaft then 1 up. Thanks for everyone's responses. I made a few mistakes but I was able to recover. In the end, it looks good, not professional, but good.

That deal is beautiful... Great job.

All mine are stainless good bad or indifferent. Be sure you use anti seize though.
