The 400 is a far more capable engine than a 305. Most guys won't even bother rebuilding a 305. Even in stock form the 400 will have much more torque than the 305. A mildly built 400 will easily produce 2X the power of the 305.
If the trans in your Suburban is the original trans it will be the 2 speed Powerglide. I personally do not like those transmissions. I much prefer a TH350, TH400 or a 700R4 for an automatic. |
I will look at the code again. Is there a way to easily identify these transmissions?
