Only reason i mention it, the Shelsley TT had the same engine and it suffered 4 engine failures due to oil surge/starvation before a propperly developed sump was put on it - although it did use A048 sticky tyres and was running 350+
Your engine bay is a lot easier to work on than mine! got to take the engine out now, but i think i'll have to rig up a vertical engine lift rather than use a normal engine crane as it doesn't have enough reach
