Lookin for some help on my 350.
Fully rebuilt sb. It is my first rebuild. But I was extremely careful and triple
checked my every move.
Stock crank. Stock cam. Stock heads(new valves and springs) new rods and
rocker arms. +.040 pistons. New plugs. New distributor. Starter is new but
it is stock. New battery.

So after spinning the oil from the distributor port I installed the distributor.
placed it in at tdc facing piston #1. Have not advanced or retarded it all.
I turned it over and few times without the plugs in to seat the new rings.
After I put the plugs in it almost fired but it struggled for a couple
rotations than it was dead in the water. Smoke from thr starter. Do
I need a high torque starter because of the oversized pistons??
More compression so that would make sense. Or am I missing
something? Any little bit of help would be greatly appreciated.

Thank you
