Thanks so much for the advice. I will keep an eye on them, I have them 2 steps higher on the jetting F+R from stock on my 770 Avenger Carb on my Iron Headed SB Stroker that Moper put together for me.

I don't see much out there for info on a street plug for sure. Racing is fun but most of my time is on the street. I wonder if I swap out the secondary spring that will keep the secondaries closed a bit longer in street driving, I have the Small White spring in there now and the secondaries come in pretty early for a vac sec carb.

Dave, take a look when you get home.....
