Did some testing over the weekend of my 557 powered '79 Mustang. We still have some tuning issues to iron out but overall I'm very pleased. We made 4 passes, 2 off the footbrake and 2 off the transbrake. Footbrake passes were a little rough due to some front end issues, but transbrake passes were solid and consistent. Best was 9.350 @ 147 (other tb pass was 9.357 @ 146).

Motor is a 557, thoroughly ported Edelbrock CJ heads (bought from Bruno), solid roller cam from Lem, Victor intake and 4150 carb. PG trans. Car is mintubbed ladder bar setup running 31x10.5W.
