Darren Smith with Pro Trans in Lancaster CA. http://www.protransracing.com/They are one of the premier Mopar and otherwise race trans builders and manufactures out there. They manufacture on site many of the trick Mopar trans parts. Sometime repackaged and sold through other sources. They can definitely build a 904 to handle that application. Just need to talk with them on how cost effective vs the benefits is that going to be vs a 727.

Steve, thanks for the information. He likes the 904 because of the low 1st gear and weight reduction. Does a 904 really make a noticeable difference from a 727 for street/strip use?
Pro Trans would be the experts to answer that question.
But I thought people had a number range of the HP loss difference between 727 and 904.

A while back one of the Mopar magazines did a favorable write-up on SMR Transmissions. The write-up centered around SMR's work with 904's and the ability to make them take serious hp. Link.

904 is about 35 lbs lighter then a 727 which is mostly internal. A 904 is at most about 2 tenths faster then a 727 with converter being equal..
I picked up .15 and about 2 mph back in 1993 went i changed...and never looked back.
all 3 cars in signature below are 904s,,,they are so easy to build that even I can do it...
there was a magazine article many years ago that listed the hp required for each trans...
powerglide was about 18
904 was 24 ...same as ford c4
727 was 45 hp...about the same for T400
and the Ford C6 was the worst...
maybe some has the chart saved somewhere
