360 smogger or not??

Again;

If you have a 360 LA engine, they are external balanced engines.

If you have any other LA small block, there internal balanced engines.

IF you want to use a internal balanced engines torque converter on a external balnced engine, you need to do 1 of 2 things.

Get the weights to rebalance the converter for external balance use

OR

get the B&M (Or other maker) flexplate for this swap.
