At 400+hp, What kills A904s?

"and takes notably less power to turn than the 727"...wtf does "notably" even mean? I've seen "60 horsepower" listed as the amount between a C4 and C6...Idiots take out a low gear 999 and stick in a New Yorker 727 (along with its low stall converter) in a Duster (with no kickdown) and then claim that all 727s are pigs. I've seen the same anecdotal argument against the th400 compared to the th350. (Some say I'm 'relentlessly persistent', but I take issue with such statements...)



I rebuilt a C4 for a guy one time. He called and said it didn't work; wouldn't even move. He said he revved it and nothing. Had a new torque converter he bought off a buddy... So he brings the trans back along with the converter. I said where's the converter? He picks it up out of his trunk with one hand; like an 8" donut...5k stall...His old worn out 302 two barrel couldn't even rev high enough to hit stall.


i wanna hear more about this .
