Twistgrip's 69 F3 340 GTS Resto

Only two rod bolts, (one each on two different rods) remain.They are shrouded by the block and I haven't been able to get a wrench on them. Still not rotating. Next step may be to set it on ground upside down and use wood dowel to drive the six Pistons that are free out of the top of the block and then use same to drive two remaining pistons down to rotate crank a smidgen. Here is better shot of top showing the turquoise original paint.
