Thanks a lot, so it seems that my block is now a virgin 390
Is it correct that a 352 service block is a 390 just bored 4.00 ?? There would be plenty of material to overbore if necessary, perfect...
The FMS cobra
oil pan has a hole pattern slightly out of center, therefore i had to grind the radius at the end of the flange down in some areas to fit the bigger dia canton nuts comming with the windage tray. Before grinding they sat on the radius not on the planar flange surface.
Out of center means a bit out of the engines centerline, but more out of center of the flange width. The holes are closer to te pan then to the outer line of the flange. I had to grind nearly 70 percent of all hole areas.
A not smoothed out grind line is what you see on the pic. I will go over all grinding surfaces again next week.
My trans is a 3550 Tremec with .68 5th. Just fine to go 145 Km/h with 2000rpm on the highway, nice for long distance travels. (long distance travel here in Germany means everything between 200 - 600 Kilometers)
May the torque be with it..without loosing anything
