That rpm level is generally reserved for SS'ers.......If that is where your target rpm ceiling is......you need to be sure everything is as good as it can be.....

RPM kills parts..........and the dangers go up exponentially as the rpms increase......I don't see anything much different on that engine than any other engine. Small block Chevy Stockers don't generally turn 8000+ rpm although some might.....and all would if they could and stay in one piece....and the engine continued to make more power at those higher rpms.

I am not so sure that 8000+ rpms is a good way to race and expect to make it thru multiple races. Generally staying in one piece is required to be successfull at racing. Stocker engines generally last a long time. Every run is not a record attempt on the ragid edge..........or one where you attempt to rotate the Earth......If you wish to race like that.....more power to you.......but making it to the next round is always a goal.....It's simple...ya can't race if your broke.....

Id like to run it lower and with what I think we have as a torque advantage Im hoping we will, my target was set it to 7500....and go from there. at 7200 shift point, (I think) stepping on the limiter all the way in 1 and 2 (set shift and limiter to same on accident) I ran a 10.87 with a soft, soft bad lauch (driver error) sooooo.....dono....

The 8k on this "spin" was unintentional....it was an error....

I agree, I do know we will start out trying a heck of a lot lower , but knowing what others are doing, and they have experienced these well.....Irv Johns, Duell, and others its not like theyre fresh, GRANTED they had better more experienced builders build there motors.....so...
