Another 408 with Trick Flow heads on the dyno

Nice rpm for the hyd cam. Did it hold power past 6600 well? What was the highest you guys reved it? We’re they full stock oem lifters or race style replacements? I’m going to use some hylift Johnson slow leaks on future build. Any experience with those?
Power fell off some by 6900rpm, that was the shut off rpm point, recorded to 6700 on the printout. They were the same lifter you plan to use!
