chevelle front end sitting too high!!

I recently bought a nice 69 chevelle and put a built 327 and th400 in it but the front end still sat like there was no motor or trans. I bought brand new small block coil springs and installed them to see if that could be the issue and nothing changed at all. If anyone could suggest anything please let me know. Everything seems right but its possible I could be overlooking something, thanks

cut a coil off of the old springs and see if you like it . do the shocks have helper springs? someting is keeping it up in the air.

I could do that but everything appears stock so when I put the motor and trans in the car should sit like factory ride hieght... the front shocks were changed before I bought the car maybe that has something to do with it. But i don't know, i suppose that'll be the next thing I change.

Shocks have nothing to do with ride height (unless they are coil over shocks). Assuming the springs are correct for this application, there are two possible issues. First, it is very easy to get the upper end of the spring out of place when installing them. It's a blind installation and I've had the top coil get caught on the centering feature in the upper spring pocket. When this happens, the car sits at least an inch higher than it should. Second, you must torque the control arm bolts with the weight of the car on the springs and the suspension at ride height. If you torque the bolts with the suspension hanging down, the rubber bushings lock in at the wrong orientation and act like additional springs, causing the car to sit too high.

Excellent advise.
I've seen this exact issue many times. Springs were not seated "in" the perch and hung up on the perch.
The a-arm bolts do need to be retorqued with the weight on them.
Other than those things, make sure the springs were are correct for your application. A-body, year, sbc or bbc, a/c, wagon, hd, etc. When I had to get new coils for my '70 Buick Skylark GS, I had 5-6 different springs that I could choose from.
After the install, it took about two weeks of driving around and the front did settle down some, but certainly not over and inch. More like 1/4" to 1/2", at most.
Maybe you need/want dropped spindles?
Could you post some pictures? How's the back end sit? Low?

The backend sits a little high too. I can't figure out how to post a picture, I'm on a smartphone right now. I'm gonna have to get under the car and scope everything out. I didn't think I'd have any trouble getting stock ride height

And you shouldn't, so either the springs are wrong or not installed properly.
