torque converter

Thanks guys for the info... ya sorry its a 351 Cleavland ( .30 over Keith black pistons mild to hot cam ported & polished fully balanced 670 cfm street avenger ) so ya if its fine then ill just keep it cause im running a FMX trans and id rather have a C6 which ill put in once this one brakes. OK... beginner question ?? The stall converter only lets the power go to the wheels at the "specified" rpm RPM right ?

C6

Will take much more ponies to turn than the FMX.
You will lose about 60hp going to a C6.

I had ran a FMX on my 351 for years, It just didnt hold up very well. The only thing I liked about it, was I could replace all the clutches without pulling the transmission out of the car. After I got tired of rebuilding my transmission all the time I went to a C-6. I dont know about 60hp but it does take more power to run a C-6, I had lost about .2sec on the quarter from it, if you calculate it out, its only about 25-30hp difference. But like stu said the FMX may be ok for you, I was pushing well over 500hp.

FMX

Can handle just as many horsies as a C6 if done correctly.

Not wanting to start any arguments or suspicions of others mechanical abilities.
Just my .02 cents worth. Plus 47 years as a rebuilder.

Ok

I was merely stating some facts so he could make his own judgement.
Your mathematical abilities never entered the picture.
Enough said.
