Going from a 727 to a 904 with a low 1st gear was one of the best mods I did to my old Barracuda.

I,ve been running a race prepped 904 behind 500plus HP SB for 4 yrs.My biggest expense was a good torque convertor.Still running 10,s weekly.:burnout:

What converter and valve body do you run?

What converter and valve body do you run?

I run an 8 inch/4500 stall Coan converter with Turbo Action RMVB.

Thanks for the info. Do you use a trans brake? And what rear end you running?

Just to update, this link is not for the grooved plates to go in the direct clutch, these are smooth plates for the rear clutch.
Are you running smooth plates in you Direct Clutch Tony??
[FONT=&quot]Alto # 027742PL[/FONT]. This is the part number for the thin 0.061 frictions that have a parallel line in them and can go in the direct clutch.

what would be a good price for having a good trans shop build me a good moderate 904 to hold good abuse and some track racing price with out torque converter ?but something like you are talking tracy ?? I have the 76 904 and motor should be done this week looking to support 500 hp ,motor should be around 420hp but know need room for early A body headers .
