They'll be synchronized. There's nothing special that you need to do assuming that "new block" derives from gr_sync_{block,interpolator, decimator}
Excellent.
However, because of the group delay in the FIR, there'll be a constant offset between the two streams. The easiest way to fix that is to use gr.delay in the path that is currently straight through.
Right, this is what I wasn't sure if it would be automatically corrected for such that input[0][N] would be related to input[1][N]... but as you stated, it's input[0][N] is related to input[1][N+delta].
I'm assuming this delay is the delay the history of the FIR filter, which is the length of the coefficients. If it's not, let me know... otherwise I shall continue on!
Thanks! George
