Spark Plug Choice
I recently had a 383 built. My builder tells me that the CR will be around 12.3:1 give or take alittle. I wanted to know what would be the best spark plug to use.
Some brief engine / veh info:
96 F-body w/ auto trans
Factory heads and intake ported by AI
Fairly agressive cam. (approximately).60x in. - .58x ex. also by AI
If anymore information is needed please ask?
