Re: no low end. can't advance timing enough?

If you have 273 gears it will kill low end. But it sounds like you have no acceleration set your initial timing with no vac advance at 10* btdc and when you plug in the vac advance it should idle up and be in 20*+ make sure the distributor is clocked proper. The vac advance should be pointing at cyl 4 abouts. Check and make sure your advance wights aren't stuck of have a crappy aftermarket advance kit. Those kits are only good for the springs
