I went ahead cut the basic shape out and drilled the head pattern, I will end up filling the holes back in but for now I need them, after cutting the pattern and drilling it I mounted it to get a level line for the top and the height I want where the 90 will end up being, one thing I do not like is spacers on brackets the bracket needs to be spaced out so I will actually incorporate that in the casting instead of spacers like are used on the oil filter bracket.

Next was to put a riser in the back to compensate for the offset in mounting, I marked the area I wanted to raise oversize cut a piece of wood to glue on to it, I taped the back side of holes and put tape on my Granite to keep the glue off while it dries, That's all for the day ill get more pics tonight of progress if the glue is dry.

Got a couple hours in on the pattern last night, you can see the riser on it and sanded to shape now the bracket will clear KE or most valve covers without using spacers



Mounted

I cut a top plate that will mount the MSD box and fitted it to back of the pattern



Fitting

I used a piece of machined square stock to hold the top plate to the back square while the glue dries, and that's it for a couple days of drying

Looks like theres a crack in your valve cover!

It does look like that, they were free I just use them for mock up ill have to see if they are not sure to be honest

Took a better look its just a scratch from sitting around they are the as cast ones at some point I might use them for more than mock up figured I better investigate

The glue was dry on the pattern last night so I bolted it up, fits where I want it and will clear factory rear mount oil coolers and aftermarket valve covers without shims, on the pattern the back does not meet the top on the sides I added those last night it is to add strength to the pattern so the top is woven in with the back (not just glued on top) it needs to be strong so it does not break when pouncing it in sand. When I cast these they will be solid but I will machine the actual part after I cast them so they are a skeleton type part.

Light sanding and some filler I primed it also last night so hopefully its dry enough for a wet sand and one more coat if so ill do a test mold and pour this weekend
