I've got an XUD9TE in my 405 SRDT wagon. I've started to get the itch for a revvy petrol engine with cams and individual throttles, and I'm tossing up between:
*getting an XU10J4R/RS engine to clean up and eventually install.
*getting just the head and putting it on the XUD9 block that's already in the car.
Both are iron blocks, though the XUD9 has the same bore and stroke as the aluminium XU9J4. Are there any other differences I'm missing?
Also, if I wanted to increase the compression, would I want to mill down the head or the block?
Would I be able to avoid a modification plate, as the XU10J4 (non-R or RS) was a stock engine for the series 2 405?
