As far as my experience goes, I've made maybe 15 passes total, and I stay right in it until I see the winning light turn on. My 60ft times are that of a 10 second car, the car lifts the front driver's wheel slightly off the ground w/out the t-brake, but if you look at the timeslip I fall off after the 1/8th mile. Regarding the cam, it's almost the exact spec as a FRPP "Z" cam. The specs are not exact but they are very close to the Z cam. I'm also running a non-roller setup because I have an older block and didn't have the $$ in my budget for the conversion kit.

So based on the mark "B" on the jpeg....is my timing off? The mark "B" is where the black line (painted at the 10 degree mark on the balancer) shows up under the timing light. Seems like I'm a bit off based on the fact I need to line up above the "B" mark (at the flat point of the timing pointer).

Yes, you read the timing marks at the flat spot on the pointer, not the circle. If your engine builder didnt know that, I'm afraid of what else he didnt know.

The fact is, from a performance standpoint, your combo is a little mis-matched. But since you built this to still be emissions legal, your 393 probably wont run like most everybody elses. All in all, I think you are doing pretty good. The only reason I suggested verifying the timing, is that its the easiest thing to check and the best place to start.

There could be several things wrong with your times. It could be as simple as changing drivers. How many times have you gone down the 1/4? Are you sure you ran the car out past the last set of cones? Its a dumb question I know, but lots of people get confused on their first few passes.

Did you ever tell is what cam is in it? Or did I miss that.
