I have a great 904 for a 400hp small block.... DON’T TRY THIS AT HOME! laugh2 I have 67 passes on my 904 off the trans brake at 4K converter flash to 6100. We go 1.21 to 1.25 60ft on good tracks, and have been running 9 teens/.20s. ALL stock components with the exception of the A&A front spring pack, A500 flat drive gears in the pump, and front band. Both clutch drums have been cross drilled for fluid relief. I talked with Darren at Pro Trans and he was like... “I’d run it!” laugh2 I’m hoping to do some major upgrades to it over our ultra short winter break.

It’s a shame.... with the 727, small 598 intake, and 4150 carb it was a really consistent 9.5/.6 bracket machine! Sold the 727 and now I have to find homes for the converters smile

Car weighs 2970 race ready....

“I don’t need a Pro Trans”..... EVERYBODY needs a Pro Trans!! laugh2
