c6 rebuild

looking for some advice before i order a rebuild kit for my 1970 c6 trans, can anyone recommend a good brand of kit to order, the trans will be going in my 28 tudor and be behind a bbf 460 with around 500 horse and used as a street rod with "occasional" pedal mashing, also any upgrade recommendations really appreciated, thanks for any info i sure appreciate it.

iv`e never had anything more than a stock rebuild on any of my C6 equipped cars .. just had a good shift kit and a small stall converter .
