What are these holes for? What size bolt?

[-JC-]

The ones next to the inlet manifold, not the top of the dizzy

[Paul G]

Probably for when an air conditioner is fitted. Granada models especially that were also fitted with the pinto engine.

Ah cool, thanks. Yeah it's a later head, was told Sierra.Thinking of trying to mount a bracket there for my megajolt coil pack

[Mc Tool]

How do you manage the oil pump drive if you remove the dizzy ?

[Paul G]

I would guess the bracket comes out over the leads and they feed through a suitable cut out in it.

[-JC-]

I'm going to leave the dizzy in place for now, for that reason, and also in case it doesn't work. I think people usually use a cut down shaft and a blanking plug.

Anyone able to hazard a guess at the bolt sizes? Nothing in my box of bits seems close, although it's such random stuff that's not saying much!

[Bug]

Kind of look the same as the manifold studs, but that's just a guess I'm afraid.

[-JC-]

Yeah I did wonder that. Annoyingly I can't find the spare studs I had

[Paul G]

M8 I would think.

[mjcapri]

M8 I would think.

Yes they look like M8 x 1.25. Unless they used fine (1.0) pitch. I still have some pinto heads including a late Sierra one but they’re not at the house otherwise I’d check....

[-JC-]

Cool, thanks. Have ordered some online, hopefully they'll do

Those holes are for mounting a SUPERCHARGER BRACKET
I put my coil-pack on the inner wing just next to the washer bottle & run the HT's along under the strut brace, less heat & vibration & keeps the engine tidier.
