Id tell you...but then someone would counter what i tell you.....I'd ask a machine shop if i were you, i bet they would know more about that than those who told you 40 or 45 and so on...lol
The only machine shop with torque plates for a mall block is Dvorak machine, and Mr. Dvorak takes awhile to get blocks machined because he has so many blocks waiting in line.
The best i can get local is a bore, deck, and align hone. Everybody has the stuff for sbc, LS, or whatever, but SBM. If I remember correctly the deck-bore-align hone should be corrulated by a specific angle (90 degrees?) -it probably doesn't matter at the power level of the crane 693901, but the next motor i build with Rusty's 693801 cam might need some of this specific machining
