Default Edelbrock Head 557 Testing

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 9.35 @ 147.

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

Thanks. We had some fuel pressure issues and timing was real conservative, so I'm sure we can pick up some decent ET. Real happy with the mph tho.

I haven't weighed the car yet. Gear is 4.11.

I short shifted in the vid at 6500. The shift light was set for the old motor. Never weighed the car, but I hope to soon.

Sounds like a nice build. I loved my iron cj headed 472 (went 9.93 in my '79 and 10.09 in my '87). Good luck with it.
