340 with edelbrock heads overheating

Early a body said

hmmm, ok yeah increasing the timing just seems like too easy a fix lol- very rare that i have an easy fix on anything lately, my luck has not been that good. , But I will give it a try i am at 12 right now I do have the fabo plate in it to lock it at 20 degrees initial. Ill bring it up till all in at 35 degrees and see what my initial timing is at.

The FBO plate does not control initial. That controls the limit to total. So, if you have it on 20 that means it will add 20 degrees to "whatever" your initial timing is. So if you increase your initial to say 18, you now have 38 total and that's too much. Your engine can likely stand "around" 20 initial......plus the 20 mechanical you have and you now have 40. Way too much.
