LO5 long block + TPI

I just picked up an LO5 long block from a '92 Suburban. It is going into my '86 T/A and will use the stock TPI. Money for heads and a new cam are not available right now so the long block is staying stock for now. What kind of horse power and torque can I expect from this combination?
