I'm building an engine for my A35, I have a sprite 1100 block, and a 12G295 head, I was going to fit 1.5 rockers and I bought a Lucas 45 Distributor, rather than the 25.

My question!

Its an A-series block, and I thought I had bought the correct dizzy, however, it seems its an A+ fit dizzy, with the larger base for the pronged clamp, rather than the bolted pinch clamp.

With a custom clamp, will it fit my A-series block, or am I best cutting my losses and getting another!?

Hope I've made sense!?

Ed

In short, yes, it can be used, you'll need to do some mods though;-

Change the drive dog on the dissy for an A type
On the dissy drive sleave that fits in to the block, weld a small tab on the side of it, in to which you'd drill & tap a hole for a bolt that will hold the A+ type clamp.

I do this mod to nearly all my cars with A series, as the early dissy clamp set up is really crap.

These are about the best pics I have

Gotcha!! Thanks very much! So will I be able to use the drive from my old 25 in this? Is it the full shaft or just the end part?

Many thanks!

Ed.

Spider is en-route on another marathon Moking adventure (east to west across the continent this time) and he's left his login details at home so he asked me to post this:

Just knock out the pin holding the drive dog in place on the A+ dissy and remove the dog, do the same on the 25D4, but make yourself a little sketch first showing the orientation of the dog to the rotor arm (so you don't end up with it 180 degrees out of whack) and then re-fit the drive dog to the A+ dissy.

Great stuff!

Still working out what I'm gonna do with the engine.... spec etc...

Tim,

Thanks ever so kindly for posting that up for me. I did the same thing (left my log in details at home) on the last trip. Doh!


Tedmcedd,

No worries mate, hope it all works out

No worries Spider, sounds like another epic trip. What's next, a circumnavigation?

Tim

Started this today... the pin in the 25 prooved very tricky to get out!?

I shall carry on swearing tomorrow!!

Ed

Sorry for going OT here, Tim, yes a circumnavigation is actually on the cards, but not until about 2016. Next year (fingers crossed) will be the Simpson, but the more I look in to it, the colder my feet are starting to get. Will be an exceptionally trickier one that.

Back OT - tedmcedd, yes, I had a few drive dog pins on which I have broken pin punches. These days if they don't budge on the first whack, I press them out.

Thanks!

Managed it in the end! I stripped the 45, and stuck the body on the lathe, turned it down so I could use the clamp from the 25 (simply because I didnt have an A+ fork!!)

Need to put the engine in now! and see if it works!!
