I wanted to but time did not allow it. The SV1 is square jetted at 99s. I will lean it out when I get some time on it. The idle and throttle response is excellent, I am excited to see how this carb works in the boat. This is the first SV1 I have tried. GalenNice. Did you try a regular style Dominator to comapre with the SV1?
Sleeper, we did not put the heads on a flow bench. Indy claims 400 cfm with the cnc385 at .800. We did go with 2.35 from 2.300 valves and Chuck and Pete at Best Machine hand blend the bowls, ports and intake. These heads run a 13deg.valve angle which they say really helps unshroud the valves at 4.5 bore. I have seen similar heads in the 410 range. Tim, ignore the left bank, we had an 02 sensor fail. Engine was on the rich side 11.6 avg. Running 100 jets all 4 corners. Since have gone to 99s. Once I get it in the boat with dual wide band 02s I will lean it out to 12.9 to 13.1 range. Galen
