I do (and I'm supposed to be cleaning up; so here are the results...) Nominal main journals 2 1/4" width 1 11/32" Nominal crank pin diameter 1 7/8"
They are for the 100 engine. They are from the 60 - 75 - 80 - 90 - 100 - 105 workshop manual so no data for 110 and the 100
(and 80 OHV unit) is an orphan with its own section. The 100 (6)and 60 (4) both use the P5 bore; the 100 has 3.625 stroke while the 60 is the same across the group above at 4.134" (105mm). For some unknown reason the figures are in a mix of Inches, metricated inches and straight metric...
Didn't you SA chaps put the twin carb 2.6 OHC engine in Land Rovers? Maybe it will match up to a P4 bell housing?
PS> With Regard Thread size try BSF British standard Fine. Which is the whitworth equivelant of UNF. The Thread Form is the same but the pitch is different. E.G. 7/16 BSW is 14 TPI while 7/16 BSF is 18 TPI
I just checked the P4 parts cattledog to see what size they should be but they are listed as "special bolt" ...bugger.
