need help 86 c10 305

[jnjlegare]

Ok I have posted a couple other times on here and now im in need of more help. I bought an 86 couple of weeks ago came with the 262 v6. The engine was shot a couple of friends said to me why dont you just put a 305 in it. It sounded like it had a couple minor issues getting it in. but its there. the vacume lines are just a mess not quite sure if they are right tried to follow the diagrams the best i could from the 6 to the 8 there are a couple of changes. now the problem is it will crank but im not getting any spark. checked the distributor cap and the coil put new plugs and wires. checked the wires im getting 12 volts to it. Just wondering if its the vacume lines one goes into the distributor. im not a mechanic and am pretty green my friends told me its not hard to do but ive hit a wall. any help would be greatly appreciated.
