Two questions...

ok... I just replaced my rear springs and front torsion bars with espo +1’s and pst bars. I replaced the rear springs first and everything was fine. Test drove to make sure there were no buns or clunks and filled it up with gas. Then replaced the t bars and when I started it up it ran at a very high idle. I did not change the front ride height to anything more or less than it was when I started. So I am slightly intrigued at why this would be this way. My two questions are, what should the front ride height be on a 73 swinger? It was 27” when before I swapped the bars today so that’s where I put it back. The other question is why would my engine be running at high idle after this repair? Could it be that the change in rake is messing with the carb? Let me know if any of you have seen this. I am planning on getting my alignment done soon and my have my shop take a peak and see if they can tune my carb better. The carb is a Holley 4bbl. Let me know your thoughts! Thanks!
