Yes Al, he did. My engine came with 10.1:1 compression, single plugs, and 172hp on an 009 in a 2165cc(78x94).
Jake, at one point, wanted me to ship him my heads and he was going to twin plug them. Claimed another 25 hp or so available.
A few years later, I called him about doing this and I was told: 1)I wouldn't make much more power, 2) my cam was wrong for 2 plugs, and 3) I should just leave it alone the way he built it. Yeah, nut there was room for improvement.
I changed my compression to 9.8:1 due to crappier gas these days, and pulled the stupid, imprecise 009. I've got Megajolt and I'm not going back. I don't care what it looks like, I care how it works. It is accurate to like a quarter degree per 360 degree revolution. show me ANY distributor that comes anywhere close, and I'll buy you several beers.
If I had to have a dizzy like Stan, I'd do it his way, with electronic controls and triggering. But IMHO, ALL distributors suck no matter how they are triggered. Crankfire is more accurate, plus it gives a much hotter spark as each coil fires half as much on wasted spark or a quarter as much on full sequential with 4 coils.
My plugs stay clean forever(I change them, but don't need to), at 0.040" to 0.045" gap.
Now that's a HOT spark!
