  1. Thanks for the input guys...Will be going with Sport Rotors Cryogenically treated slotted Brake Rotors...I'm going with the slotted rotors instead of the Cross drilled is because in my personal experience I've found that the drilled rotors have a tendency to crack outward from the holes... Under extreme severe use Braking conditions...(Nascar short track ovals) The car is mainly driven under normal street use conditions....But it has  occasionally been run on the track...and Routinely  speeds over 100 + MPH on my favorite road course (Blue Ridge Parkway)...Will also be going with Hawk HPS Ferro-Carbon pads.. Any final thoughts/comments Would be appreciated Before I push the Order button...Thanks again guys...16496881943786694777304886119710.thumb.jpg.54b5b705ef8b93384940578fdc6d61ea.jpg16496876887308093567024130547893.thumb.jpg.f47df16971da9b1da647b98df11cdd4b.jpg

  2. Like the TA...Had a very low mileage 86 that looked Identical to yours...Mine had the L69 (305 HO) engine with a 5 speed manual transmission...

    It Was destroyed in a head on collision with a Sunbird back in 2004...Was very lucky everyone was pretty much able to walk away...

  3. Easiest way...To Access the starter wires...Before lifting/Unbolting the engine...Drop the starter from Underneath...Support it so that it is not hanging on the wire harness...The wires will then  be easily accessible...Then use a 5/16..??...Socket or wrench to take the wires loose from the solenoid...Having the starter off the engine can actually be beneficial...Clearance wise when removing the Mill...Anyway..

    Are you removing the the engine and transmission together as one unit..??

  4. Judging by all the corrosion that I see in the photos...My guess is that the whole electrical system is full of bad grounds...Would start by cleaning the bolt connection lower left corner of the fuse block...Then maybe go to all the light sockets including the License plate light and make that they all are clean and crap free and that they are grounded properly to the chassis..The light sockets themselves are grounded individually to the body when they were pushed in and twisted into the mounting holes instead of having separate ground wires from the sockets to the body...Had a rusty mid 70s Oldsmobile cutlass that had lots of electrical gremlins (Came from upstate New York) ...99% of which wound up being corroded grounds all thru the car..The reason I single out the License plate light is because the light and fuel gauge/sending unit were on a common ground...

    Basically every ground connection strap/bolt..etc.. inside and out or that you may suspect is a ground that you can find should be cleaned and retightened...

  5. Other than the .030 over bore...Is the engine still basically stock...?? 

    Are you running a radical cam profile...??

    Are you still  running the factory Iron cylinder heads...??

    Is the Fan shroud in place/undamaged...??

    This may sound crazy..Are you 100% sure the Temperature gauge is accurate...??

    Something else that may sound crazy...When running an engine without the thermostat to help regulate the flow rate of the water...The water flow speeds up through the engine and it doesn't absorb the heat nearly as efficiently as it should... When it has some kind of a restriction (thermostat) to slow the water flow rate to allow for more efficient heat absorption....Something you might try...Instead of running a thermostat...You can try a water restrictor...Basically what they are is a round disc that looks like a washer that fits in the housing where the thermostat normally goes...But they they have different sized holes from larger to smaller and you can actually speed up or slow down the flow rate of the water thru the engine....Independently of the water pump flow .... Depending on what size you install...They are available as an inexpensive kit with different sizes included...You can get them thru someplace like Summit...

    Might be something to consider....
