Starter Problems
A few thoughts on your problem.
1. Always buy the best starter you can afford. I use the Powermaster
that is recommended for Pro Stock/Comp use. I hated to spend
the big bucks, but now my spare starter is a paperweight.
2. Never...never, buy a cheap flexplate.
3. Since you're using a MSD 7AL-3, make sure you have "zero degree" chips in any of the unused retard positions on the box. When I FINALLY
realized I didn't have them in mine, starter problems went away.
Hope this helps...
