2800 to 3800 Converter change But Still Same 60', Why? Can someone explain to me why going from a 2800 converter to a 3800 converter does not produce better 60’? I have been told that since I only have a 3:23 gear it would not benefit from a 3800 converter. My car has 400RWHP and 379RWTQ.
Can someone please explain in plain English why there is no benefit? I am ordering a new Strange 12 bolt with 3:73 or 4:10s.
Thanks,
Bill

there is a benefit - as long as you can put the power to the ground. you're gonna need a really good tire to hold your power with a 3800 stall. theoretically, as long as your traction is the same with the 2800 converter and the 3800 converter, your 60' will improve.
whoever told you that is full of ****.

Stall speed matters to 60' if it puts you to a better
engine torque point on the curve, off the line. On a
stock motor this may not improve things that much
as the torque curve is flat or fading above 4000RPM.
In general the V8 makes a fairly flat torque curve and
torque is all that matters to 60' (when you can hook).
STR is what raises actual delivered rear wheel torque.
STR -tends- to go up with STR but that is not always
a given; you could find some 2800RPM "truck" converters
with more STR than a standard 3800.
Beyond the 60' mark the power delivery starts to matter
more than plain torque (power=torque*RPM) and the
higher stall, even less efficient, can deliver more RWHP
through the range that would have been stock midband
on a MPH basis.
