Last summer I replaced my intake, carb and distributor and drove it about 2 weeks before it went into the shop for new rockers and a lot of other rust/rot related fixies. Several months later we're back on the road and she runs less than 1000 miles before she dies with a fried coil and ICM. Maybe all the welding fried these solid state components? Had it fixed and it lasted for about 500 miles before it went dead again. Looks like the ICM again. Anybody got any clues as to why she seems to be eating ICMs? Also, the new card/intake setup creates a lot of black exhaust. I'm wondering if she needs a wider gap/hotter spark setup or is it time to consider replacing the stock 305 heads? Compression is high and I get some knock even running 93 octane. Any ideas would be appreciated.
