Can't get it to idle right! (Part 2)

Buy the right pushrods, could not get my small block 340 to idle worth a crap without welding up the mechanical advance slots and filling them to make the slot around 1/8 smaller, then set your total advance to 35 degree and you should be OK. If your not sure what size pushrods you need you can buy a comp cam adjustable pushrod to get the geometry right, had to do it on my motor also.
