Guess ET for 318 ? With slicks ???
Flatlanders/isky are full of it if they think that 224 hyd cam will roll to 6500 in a 318. It may get there in a 273, still doubt it. XE268H comp cams, 224 at .050, with more lift fall off in 340's right about 5300-5400. 360's about the same range. Comps range for a xe268h is up to 5800.
I'd bet it's falling off at 5300-5500. I did that way back with a bunch of people, they shift at 6000, I jump in it and shift at 5500 and the car picks up. Try it and see how it does. Sometimes it will flat fall off once you get beyond a certain RPM, et wise. Seen cars that peak at 5500, shifted at 5600 and it lost .10, whether you shifted at 5600 or 6000... didn't matter the et was gone.
It might actually run pretty good with the 2.94's and slicks, act like a glide. You might be able to really lay into off the line and work the converter HARD.
60' is more important than most anything else at the track. Start trimming that down and you'll see ~2x that most of the time at the 1/4 pole. 60's below about a 2.0 and better closer to 1.9 should yield a 13 second time slip.
