balancing my 383
hey guys. new to the site. i am building a 383 to swap into my 86 iroc. i was wondering about balancing the motor. i have a cast eagle crank, eagle i beam rods and speed pro hypereutectic pistons. i am having the whole assymbly balanced before install. i know that traditionally these motors use the balancer and flexplate off a 400. which is externally balanced. so what i am wondering is, what balancer and flexplate do i need to use with my internally balanced motor.
thanks guys
thanks guys
