T 350/400 torque converters

[bonnie john]

are they different ?

i bought a second hand Turbo 400 and it came with a converter marked "Turbo 350"

but it seems to fit and engage fine

I would call Summit Racing at 180-230-3030 and they could answer any questions you might have better than me.

They will interchange, however a stock 400 converter generally has a larger diameter and lower stall speed than a 350 one. This is assuming that the 350 is a non-lockup unit.

As long as it is non lockup they are completely interchangable.
