UNmolestedTA

I need a little help with my combo. I recently acquired a 5.3 4l60e pullout for my 67 camaro. I am not sure of the mods that I need for my tranny. I know that I will need a stall but unsure what rpm. Also, my goal is 500hp. I want to run 3.73 gears outback but I have't purchased any yet. Lastly, I am planning on keeping my weight to about 3200lbs if possible as I am unsure of how much 67's weigh. I am open to any and all ideas for my transmission, thanks. Mike
