Lsx sfi rated flexplate question. I need to move my plans forward and get an ls7 crank rebalanced to suit my rod/piston combo. I'm going to use a TH400 but I haven't bought the flex plate or bolts yet. What do I need to know about flexplates for this combo so as not to get it wrong? This is a blown 427 and this is the first time I've gone auto so I could easily make a mistake.
Eta, we need to add some weight to the crank, about 20 grams so an externally balanced flexplate would help. The ls7 cranks already been balanced so adding weight could be difficult as it's already full of heavy metal.
I've just seen this on ebay, would that be suitable?
