    Can I bore 0.060" over?

    Seriously doubt an early block will go that big Adam, they could sonic check it before attempting it.

    How hot is considered overheating?

    The Electric pump is plumbed in series with the mechanical pump as both can flow through, I ran the EWP with the MoTeC and had it run at low road speeds, idle and high engine speeds covering the lack of pump flow at idle and cavitation above 7500 rpm.

    I ran an EWP as a booster in my 7M, it helped a lot.

    Changing my head gasket, me asking for your help while doing this

    Puts it into diagnostic mode so you can adjust the base IGN timing without the ECU fighting you for control.

    Changing my head gasket, me asking for your help while doing this

    It's marked on the outer ring so if it slips in relation to the hub that's keyed to the crank then yes. (quite common and if you time it to the incorrect mark ALL of your timing is wrong Cams and IGN)

    Changing my head gasket, me asking for your help while doing this

    The outer ring is bonded with rubber to act as a shock absorber for the crank, in operation each time a cylinder fires it whips the crank from the front to back, the damper absorbs this.

    Either buy a new Damper or remark yours keeping in mind once they start to slip they don't magically stop ;)

    Engine overheats on highway with AC on

    It's one of those things people seem to think are unneeded... they're often binned but the reality of a Mk3 is it's got a tiny frontal area and air foolows the path pf least resistance so if the blockers and tray are missing the Air spills off the radiator and around/under the car and you get a...

    Changing my head gasket, me asking for your help while doing this

    #1 Have you checked to make sure the TDC mark on the damper is correct? (chopstick in the plug hole wind the crank till it stops rising and check mark) 7M dampers do slip, it's very common. #2 Did you set the cam timing with the belt tight on the drive side? (TRSM has some detailed...

    Changing my head gasket, me asking for your help while doing this

    The 2 offset holes in the Can Pulley are to correct for this. The Tensioner bolt is either M12 or M14 x 1.25 pitch and being so massive and bolting into #1 Cylinder's wall is what pulls the bore, in the pic I posted above you can see where the rings had never touched that bore... :(

    Engine overheats on highway with AC on

    There are a bunch of smaller blockers around the Rad that are lost over the years on these cars as people don't understand just how important they are. Possibly, resident time in the rad is important (more a SBC issue) but I don't think the 7M waterpump moves enough water for it to be the...

    If the Tensioner bolt is so tight it's stripping the Block is fucked... Even at the correct 36 ft/lbs torque it pulls #1 Cylinder half a thou.
