Edelbrck vs Trick Flow

It is very possible. Like I said earlier pan was full of metal, not a flake or two, a bunch. 60' in my opinion should have been better. Went 1.47 once and after that just hovering around 1.50, leaving at 3000rpm. We will see how the new to me trans and converter work in a few weeks.

Yes the converter is likely the problem...and the more power you put to a bad converter the slower it'll go even with more power. Converters are KEY!! I've had several customers go through this and blame the engine, only to find down the road it was the converter.
