Re: Comp XE268 power band
My timing is set at 35*. We tried bumping up the timing to 38* and down to 32* and it liked 35* the best. I'm running a Comp 980 valve spring with 85lb at the seat. I was thinking it might have a little valve float. Driving the car it feels like it pulls to 6K easily but on the dyno it shows it dropping off. Could be that the engine revs so fast that I just don't feel it dropping off.
