The a15 has 8 ports. It sounds like a Datsun engine. Most special cars have their own special sound. The A-series, VW beetle, Jag V12 for examples all are special in their own way. I don't think you will reproduce the British sound with the Datsun engine.

It also depends on what you do with it on the muffler end.
Whether you put on a tube style exhaust manifold or stay stock.
What size pipe you use.
On my A15 I had a Monza style quad muffler which had a throaty sound, I recently switched to a 24 inch Screamin' Eagle Harley muffler with baffles intact.
This has a much lower grumbly sound, and if you punch out the baffle the sound changes again.
If you use a shorty Harley muffler the pitch changes significantly.
I have heard plenty of stock Datsun 1500's and none of them sound like the one in my car. I suspect the SU carbs also effect the output sound, at least I noticed a difference in sound when I switched from the Hitachi downdraft to the twin SU's.
My car doesn't sound exactly like any other car really, it's unique - people know it's me coming from a ways off.
So changing things up a bit can produce a sound tuned to your likes, but I think it would be difficult to get to sound just like a stock spridget.
Maybe it would be a little more spridgety if you used a small pipe leading to a very constrictive muffler, but that would effect performance badly.

So does the Spit 1500. Mine sounds like (IMO) a Spridget should. it doesn't sound like a Datsun. Is the firing order different b/w Dat and Spit?

Hmmmm, the same. Well, then it must be the oil leak...

I think a lot would have to do with the valve timing. Cams are usually profiled from many many tests on a test engine. Therefore what profile works well on one engine doesn't work well on another. Thus the unique sounds.

Lets try it, I made a few short videos with my phone the other day and just got around to converting them to a reasonable size.

It's funny the times it really gets loud and the times it seems quieter are very different compared to my old quad monza setup.
For instance there's a hill leading out of the valley here up to the freeway, when I hit that hill in 4th gear at about 35mph the thing just gets growley.
