<p>Mike, when I ran an overdrive, I was running a 4.11 rear end.
Without it, I run a 3.8 (Ford diff), and have seen 6300 or 6400 at
the end of the straights, but that's a really hot lap. I normally
peak at 6100 or 6200. 3.7 would be somewhat better, 3.5 I've not
tried but should keep you under 6K.</p>

what would be the ideal rear end ratio for a TR4? Last time
(2013) it seemed I could have used a lower ratio?
