Greetings folks, I'm just started a rover powered Locost project,
I'm planning to combine the stock fuel injection system with a Megasquirt set up.
The main question is can run the car without a dizzy, I'm aware that the oil pump is driven by the dizzy, but can i use a cut down dizzy stem (the lower portion) to retain the drive for the pump?
Many thanks in advance for the first of many questions.

In short yes you could.
But why not using a Serpentine front instead?
The Serpentine front will fit, depending on your engine without or with minor modification on your crank.
The benefit is the Serpentine front has the crank driven oil pump which is a better design than the dizzy driven pumps.
The Serpentine fronts are on ebay on a regular basis.

the very late 3.9 serp front cover fits without too much problem but I dont think its so easy with the 4-4.6. http://www.v-8.org.uk/forum/viewtopic.php?t=92

Yup i'll vouch for what Marki (katanamman) says.
I've just changed from an sd1 front cover to a 3.9 interim serp cover.
The 4.6 cover requires the 4.6 sump and pick up pipe also but has the dizzy hole blocked up as standard.
The 3.9 one would use your original sump and pick up pipe so makes life alot easier.
The only pain with both is that you'll need to change the woodruff key on your crank. The early 3.9 and 3.5 cranks have a short key whereas the later 3.9, 4.0 and 4.6 cranks have a longer key to engine the cam pulley, oil pump and bottom pulley. This can be sorted in two ways.
1. Grind a longer keyway in the crank, the early crank key way is deeper though so you'll need to use a bit of chemical metal to fill up the difference in depth. Sounds like a bodge but Rob at v8 dev's told me to do it this way and he's never had a problem doing it this way. This is fine if the crank is out or you're confident about doing it in the car or you can. . . .
2. make your own woodruff key which sits in the original hole but is long enough to engine the crank pulley too. This key would be weaker but the high torque setting of the crank pulley bolt should be the one taking the load not the key when its all done up not the key.
The 3.9 serp setup looks the part and is very compact and solves a couple of problems as well as making the engine lower maintenance. I'd go for that one!

Lol! If you add rangeroverheaven as yer favorite seller you can keep an eye on him for another.
Alternatively if you contact Alan that runs it he can notify you of when he gets another serp setup in. I was there today funnily enough picking up a cross boltable bottom end from him and i think he may well have another there from that engine.
