Ignition control module 77 454

Was curious? Knowing my ICM is getting hot, I have to replace every summer when weather starts to warm up. Everything Is new in ignition. Hei, plug wires are ceramic ends 8mm to protect against aluma coated headers. I read in a forum that there might be high resistance in the plug wires. I’m going to replace the spark plugs with new r43st, for cooler type spark. I usually replace ICM with AC Delco oem. If anyone has any timing advice, it’s a semi modified motor. The cam is 500/500. I was told it’s probably a little more performance than an Rv cam. So, with all that in mind, would love to hear some idea’s. Thanks in advance for any and all help.

When you replace the ICM clean the backing plate of all the old heat transfer paste, and apply a good coat of new heat transfer paste. Make sure your distributor hold down has clean metal, this is the distributor ground. Double check your engine ground. R43 is a good plug, I run them in my truck.
You shouldn't be burning out an ICM yearly. My ICM is 2019 and spent the last 3 years in AZ.
I would try the timing at 8°-12° and see how you like the way it runs.

Great. I’ll try all the above. Thanks. I tried an after market, electrical paste, from a electronics store. It has a crazy heat rating, is why I chose it, like 2000 degree’s of protection. Thanks. I know these things are supposed to last longer. But my engine temp stays reallly good on the gauge , but the compartment gets extremely hot. And more so on hot days.
