It’s going in a 70 swinger I just want to be able to get on it in a straight line from a stop or a roll. I would like to keep my 904 auto trans and I have an 8 3/4 stock rear.
Building a car around a cam isn’t a great idea but it’s the situation I’ve got myself in. I’m just wondering what else I need to do top end to get it running well.
Stock had different ratios. Have to mark both wheel and drive shaft, then spin the wheel and count how many times the drive shaft moves. Ie one wheel spin the drive shaft moves 3.5 or 3.2 or 3.7 or 3.9
