The mods to a SU6 will result in it flowing similar to a HS8.
The stromberg is a good cheap carb and personally think it is better than the HS SU carbs. Mine works really well. I just want to see if the extra flow will give increased performance and if I can get performance close to the B20B. Just having a play.

I've always used Dexron II-D in Strombergs and SUs as well. Given that you're running a bit lean at the top end, 80W90 would work well too.
The limiting factor on an HS6 will always be the 1 3/4" diameter, the HS8 will give that vital extra 1/4" diameter or you could opt for twin carbs of a Weber 38DGV conversion which is in effect twin HS4s in terms of flow area but are easier to alter the jetting.
What other mods have you done to the engine?
