For a Hardcore setup with max TQ comming in at 4500 and max HP comming in at 6300,This car is shifting at 6600 rpm...

EG. 6600 shift back 1500RPM,1200,900 etc?
Thanks....

 

If you get a longer shift extension, you are generally getting extra torque multiplication from the converter. In your case you want a converter that stalls to around 4200rpm and has a shift extension of 5400 - 5800 rpm (assuming it is holding the extension efficently not just a too small converter being stretched).

 

WOW that is great to here Rag..
My converter flash stalls right to 4300 and if I shift it at 6600 it drop backs to 5300 but that was with the tired shortblock

VIG told me I might see alittle more flash stall/SE with the new motor since it wont be down on power.

I might need about 200 RPM more flash/SE and if thats the case then I'll send it back for a free upgrade and a 3 Disc clutch....

Thanks for the help.....
