Hi guys I have an 89 Iroc, manual tranny. It used to have its stock tpi 305 but we recently threw that out (along with most of the a/c and heating components) and just finished installing a carburated 383. Today we took the car off the jack stand and noticed that the front end sticks its nose up about 3 to 4 inches higher than before. The new engine must be much lighter than the old.

My question, WHAT do I need exactly to lower the front end to where it used to be? Im guess 3 inches total in the front, and the back im not so sure it needs lowering at all.


Thanks fellas!!

 

3-4 inches higher! not a chance. I imagine its slightly lighter with aluminum parts ect. but....

The springs/shocks just have to settle, give it a nice heavy jounce. Also make sure springs are seated correctly.

If its still a couple of inches higher or even really 4" like you say, drop spindles in combination with lowering springs. Suspension geometry will be off.

 

yeah it really is significanly higher than before. we have a table on the side full of stuff that was not reinstalled. thanks for the advice!

 

Springs did not settle right.

 

I don't care if you took out 200lbs worth of stuff it would not sit 4" higher. There is something else wrong.

 

thanks sooo much for the help guys. in a couple days when i resume working on the car i'll see where it sitting at.
