What size are your Strombergs? These are not XU1 carbs and manifold.
Also noticed no vacuum advance pipe to the dizzy. Has the dizzy has been modified to mechanical advance only?
The carbs are 150 stromies and not sure of brand of manifold, I'm tempted to get xu1 manifold and 175's down the track just to fill the 2nd hole in my rocker cover correctly but then I think there's no need as they are not a factory fitted item anyway and it's not an xu1, it runs well with the set up its got so I'd like to see it fine tuned.
I'm not sure about the dizzy that's a bit past me but know it early commodore.
See S pack I have this problem, I really wanted an Xu1, I had one lined up at a good price and the sale fell through, I saw this car and 2 other people wanted it at the time and I had to make the decision I jumped on it cause of its matching numbers and even though the sale fell through on the xu1 it wasn't matching number car.
So now I'm torn between not much work involved in putting a bobtail and 175's and extractors on it and a sticker kit or keep it a tidy GTR with period tripples on it. I can't have my six without tripples, there's nothing like the sound of butterflies in the morning.
+1.
Also, your timing is still up the shit if thats 18 initial.
Difference between initial and total is as follows.
Initial timing is taken whilst the engine is at idle. If the dizzy is properly graphed to suit the engine this will be with the mechanical advance at its most retarded point.
Total is taken somewhere in the rev range once the mechanical advance is fully advanced. I say somewhere in the rev range because this depends on the dizzy, whats done to it.
I usually go for between 8-12 initial and 22-28 total, depending on the application.
Yours being mildly worked you would look at about the halfway marks between them bordering on the lower side, so 8-10 initial and 24-26 total, depending on how much mechanical advance is dialied into the dizzy and when.
I fully appreciate the whole idea of doing it all once the gaskets are changed though, no point frOcking around now.
How much experience does your mechanic have with these kind of engines?
Cheers.
