I don't think so. I've upped and decreased the timing, raised and lowered the shift points, I've not worked with the jetting of the new carb. But it's mph'ing really well. and it picked up a few hundredths over the pro systems carb. More compression and a ported intake would probably help. But at that point will the block handle it? Who knows?
You should be proud how dialed in and well the combo runs! And to top it off seems like it has been pretty reliable. What is the timing and shift points you settled on for best et with this combo?
