I would like to more closely look over the toyota six and see what improvements were done that could be adapted to a 235 or if it can be made to look like a 235 easily and use one on my next project or if the 235 in my 37 dies. From what I seen so far is I like the waterpump design and placement in the block and a full flow oil filter system and possibly a better bellhousing mounting surface cast in the block. Tomorrow I am going to crawl under the guy at works landcruiser and investigate more thourghly.
