I don't have any info on my motor and would like to have it dynoed.Would a engine dyno give better info or should i leave the engine in the car and run on a chassis dyno. My other concern is my converter flashes to 5400 so would that mean i wouldn't have any info below 5400? 408 with 590 cam and mildly ported eddy heads.
