i will be putting a modded D483R pulsar dizzy in my 1411cc stroker (how come you got an extra cc Doc, was it just a rounding error??), but it also has a 282 cam, will have a GR head, ported inlet manifold, 45DCOE weber, and has a rebuilt rod change with a Fred Sayers LSD in it.
As to why i chose the D483R, well with all the mods to the engine i would have had to have GR mod a points dizzy curve anyway. Frankly, as the 2 year engine changeout for my competition car

shows, i have very little time or budget to work on the thing. So whenever i want to prepare the car for a track day, or whatever, one less thing to check (points gap) just suits me fine, as it is a few more minutes saved.
The engine is being built as a package, not a hotch potch of bits added on. I went to Graham, and told him what i intend to use the car for, what engine block, head, crankshaft, manifold, gearbox and budget for rockers exhaust etc were, and he has designed the package around those requirements. One of those requirements was reliability. As a result the dizzy will be modded using the dyno and the intended use and reliability requirements in mind. The maximum advance will be set using the dyno.
I have already pulled the dizzy apart and Graham had a look today. It was not the worst he has seen, but definitely needs cleaning up. I will do that and the oilway mods this week.
We shall soon see what it produces on the dyno, and i'll report on its reliability when i eventually get to use it.
I guess what this shows is it is a horses for courses thing. A pulsar dizzy is no cure all for a dying engine. if you are going to bother rebuilding an engine it is wise to rebuild all of the anciliaries as well as the guts. If there is a well priced alternative that you can rebuild and modify for the same price, then why not?
Another alternative is to go to jaycar and get a transisterised ignition kit, and build yourself a very low voltage circuit that does not destroy the points, and all you need is a soldering iron and literacy to make it work. That way you don't have the expense of a pertronix, but still have the same curve your engine was made with (assuming the engine and dizzy are stock and matched)
cheers
