Re: Dyno'd the 71 yesterday...
480 engine dyno
364 chassis
just use the chassis dyno as a tuning tool , get a base line and inprove on it . Drag strip will give you real world #'s
I started @298 hp on the first pull (vey humbling). Timing first , then carb . This was a new combo and alot of untested parts . 11 pulls later power dropped off . Went back to last pull and duplicated it . Truck went from 12.28 to 11.75 in 1 week . The guy running the dyno was learning how to change jets from me . He had never seen it done , he works on all fuel injection cars . This also was a mustang/lightining shop . i meet the owner in the staging lanes @the track . I set the a/f ratio @12.8 and he said the curve looked better than most of his fuel injected curves . Nice and flat .
