Just joined the other day. Bought an 87 GN last year at this time. Had it shipped home and had to yank the engine out. Cracked #2 main cap. Got steel ones from Cottons Perf. Also purchased many other engine parts from Cottons and TA Perf. Engine is back from machine shop and is in the car last week. Will be finishing it tomorrow, and hopefully I did it right. Keep your fingers crossed for me and I'll update later.
