Do I need a new gas pedal? 6/ to v8 swap.

My slant was a one owner and then sat in a dirt floor shed for a lot of years so it was all original. It had air and the carb has a throttle cable. I built a small block over the winter and I don't think I will have to change it when I drop the 8 in. Looks like it should connect with little if any modification. Oh yeah, it's a 66 Valiant with a 225 and auto right now.
