Thats good... but dont stop there.. if you jetted up 2 sizes and it picked up then go 2 more till your MPH starts to drop then back up 1 size... then after you find the sweet spot then advance the timing some but watch your plugs..... good job

Not too shabby, have you tried 34° timing yet? All our SB's love it. Making a timing and spring change together you really can't credit either. Just my .02
I would have said 34* or so also but with my last SB it liked 39*... we didnt go higher.. I said 39* was far enough... so test, test and test... dont ever think that should be it...........JMO

Timing started @ 35. I dont think the mono leafs changed et much because 60fts stayed the same. I was looking more at the mph for the hp increase. 112mph then 115 now, same DA @ 1000 ft.

Good deal! I started out with a 71 scamp that had a mild 340 in it, ran 11.70s at 115 at 3200 pounds, lots of fun and very streetable!

Actually if the MPH went up you are making more power so the 60' should have dropped some if it was hooking up right... like I said before.. keep going fatter till your MPH drops
