I've got a 69 with a 327 300 HP. Front end sits to high and the car leans towards the drivers side. I've replaced the mono rear leafs with 3 leaf. This didn't fix the lean but one spring was broken so I had to replace them anyhow. Not sure if someone has put BB coils on in the past but I'm going to put on the SB coils hoping it'll level it out and lower the front. Any advice on what type of shocks I should put on? Don't want to spend lots of money on these but I'd like something that works well.
I would look at the subframe bushings too. Just looking at them might not be enough. Sometimes the frame will rust out between the bushings. Radiator bushings or rot may make the car look like it is leaning too. I have KYB shocks on the front of my car. They are ok I guess, I dont do much high speed turning, but did upgrade the sway bar.
