Hey everyone. As the title states.. I have a '73 Camaro with a TH350. I'm eventually looking to swap to a manual, but I'm hesitant to cut the trans tunnel. I would really like a T56 so I have a 6 speed. My friend is trying to convince me to just go with a 4 speed, but I feel like that won't be enough gear. Although, it would probably be significantly easier than swapping in a newer 6 speed. So, are there any transmissions that swap in without cutting up the tunnel? Also, opinions on the "stocker" 4 speed vs. anything newer (t56/TKO)? Thanks fellas!
