Well it is what it is, but I see what your saying is correct. I'm the crew for next year and my mate isn't really a hard core racer tbh, too laid back, so I'm just trying to get as much info on it as poss to have an idea of just how hard we should push things with it in the future once he gets fed up running mid>low 10's and it all stays ok. We'll get it run in down the 1/4 and keep an eye on it. Are these blocks good for cooling or do they have any issues is another thing that would be good to know, we'll find out of course but a heads up would be good, that no.7 is thin if any of these numbers are correct.
