Sounds like
convertor might be knocking 60 foot out of it. Too tight?


Converter could be too tight, I don't really know how to figure that out given the info I have. He has the transbrake set at 5800 which seems like an okay number. Once I see the dyno sheets I'll have a better idea of where the torque curve is but 5800 seems like it should be in the fat part of the curve for a 540 engine. The car doesn't push thru the lights so the converter isn't super tight. I'm not sure where the stall speed is since the car doesn't have a driveshaft speed sensor. I think he shifts the car at 6600 rpm which seems a bit low for a 540 with good parts but once again, I haven't seen dyno sheets so I don't know where the power peak is. He did say the car went faster when he shifted at 6300 so maybe 6600 is a touch too high.


5800? sounds like the converter is way too loose , just from that. If this converter was too loose, it would pick up in the 60" AND MPH.
Get with a good converter company.
My deal is totally different, but my converter goes to 2900-3100 with NO chip or limiter.
What size is the converter and what company??

My buddy has a nova, 3600lbs. With a 565 it goes 9.30's at 142-144. 60' are in the 1.30 range
Heck, my sons car going low 11's 60 in the 1.40's

Almost any change I make to my car...I get the converter looked at and sometimes changed.
