383 motor

[77mesa4x4]

Does anyone know what all is needed to convert my 350 to 383, other than a sb400 crank.

You will need a 400 balancer and flywheel "flexplate" if you use a 400 crank. Check out the previous post on this topic below.

To get that displacement, your engine has to be bored 30 thousands of an inch also, to 4.030"
