I am soon going to attempt installing my newly refurbished engine into my 4.2 Tiger. However, I do not know which bolts to use to connect it to the gearbox for starters, along with numerous other items. I have seen the boltlist supplied by Kirt Jenssen, but am not sure which bolts are unf and which are unc. Does anyone out there have a definitive bolt list with these details - the Alpine parts list seems to have those details, but the Tiger one does not !! Any advice would be much appreciated.

pretty much all the engine bolts (ford) are coarse (UNC) and most of the sunbeam bolts are fine (UNF).

the gearbox->bellhousing bolts are no exception and are UNC. most tap/die sets come with a little thread gauge to hold against a thread and find out the TPI (threads per inch) hence indicating UNF or UNC.

with those bolts, you'd probably be fine with a normal bolt like those from www.namrick.co.uk and a lock washer but for bolts like crossmember and suspension bolts i'd recommend getting rolled thread high tensile bolts from a caterpillar (CAT) dealer. see my previous thread on UK vs US bolt standards, and apologies for the extended response - its a subject close to my heart
