406 cylinder sleeve
i have a 406 i was getting ready to assemble when i noticed a small sand pocket or hole in #3 cylinder. it will be where the rings are. i am building this for 1/8"mile and it has 13.7 comp,solid roller and internal rotating assý. if i have a sleeve put in is it going to hurt my block, it's the only block i have for this assý. i just dont want any issues. CAN'T AFFORD A DART BLOCK ANY ADVICE IF THIS IS ACCEPTACLE THANKS JUST DON'T WANT TO RUIN ALL THESE NEW PIECES BY CHANCING IT OR NOT REPAIRING IT PROPERLY. NEED SOME HELP!! THANKS
