Hi Jim, dont think i have this bolt? any way i can check?
i did run the engine quickly before getting it into a load of pieces...i also around six months ago complete a compression test on the 261, they where all in the 100's..but didn't set the tappets, (cant find the exact results) thats was good enough for me.
the plan was to put my old 235 in and work on the 261 ..when the trucks on the road....not possible now...
ive spent out on everything getting the frame and running gear sorted! its all new / reworked..only thing i couldnt do was straighten the springs...
