starter/flywheel issues

:banghead: Hey guys, I have an '86 K5 that has had a muncie 465 and a 350ci swapped in. I'm having problems with the starter/flywheel. I went to the local parts store and picked up a starter for an 86 blazer with a manual and it doesnt seem like its the right one. I have shimmed this in all possible combinations and its still not right. when i get under the truck and watch while someone else cranks, it looks like the pinion gear is engaging all the way, but its not meshing with the flywheel. Then, i turn the flywheel by hand a bit and then it grabs but its too close. I didnt do the swap so im not sure what the tooth count is on the flywheel. Any suggestions? I'm desperate........thanks

you have the wrong starter then

you do not need shims if you had the right starter nose

12.5" wheel = straight across starter nose bolts

14" = staggered bolts

get the opposite one

you should have 1/8" gap between the outer edge of the flywheel, and the shaft that the starter drive gear rides on


if not then get the right starter nose on it
