Dyno Question

[84GNwith87eng]

For a fairly stock 86-87 motor, when tuning on a Dyno, around which mph range would you cut out?

Thanks people, just want to be safe and not hurt the motor

Well first of all I'd do it by RPM not MPH...And with a stock motor I'd just pull it until it stopped making power, for instance I'd stop the first pull around 5200...Look at the dyno sheet and if the car was dropping off HP then I wouldn't pull it any harder, but if was still making power, I'd pull it alittle higher like 5400 or so...If it's a stock cam or close I doubt it would make any power past 5200-5400, and even lower then that if the valve springs are getting weak.
