A few questions on front suspension.
#1
Ok some of you know I hit a curb last summer and bent my tie rod end. So I will be changing both sides this year with moog parts. I will be getting the inner and outer rods + sleeve. But one of my other problems is my car seems to have very soft suspension.
I have a deep oil pan but even before that. I would bottom out on any drop in the road. I have new shocks in there but they do not seem stiff enough. Also my car originally came with a 302 But now it has a 351c 4v with an aluminum intake. And the shocks I ordered where for a 4v car. Should the coil springs be changed. Can they have become to old and are not doing their job. I will be going from 14 inch to 15 inch wheels also. I do not necessarily want a rock hard ride but Getting pretty sick and tired of scraping the oil pan and the headers on the black top. Undecided

Any help or suggestions would be appreciated. The rear seems fine to me buy the way.

The 351C outweighs the 302 by about 90 pounds, and as such, 351C equipped cars had different (higher rate) springs in front. A/C will also make a difference in the weight on the front of the car.

{thumbs up} You mite have to get some stiffer springs up front if your not happy with how she feels...Plus after time springs can go bad and relax a bit....Im sure its a bit of both...Motor a bit heavy for the old springs...The old springs not being stiff enough in the first place.

New springs for sure..You've done just about everything else..Even a car in storage sitting on the suspension will wear out a spring..It's one of the reasons they tell you to support the car on the frame when putting a car into storage so the suspension is "unloaded" (besides the issue of flat spots on the tires)

My understanding is the I6-250 and 302 shared one set of springs, and 351 and up had another.

Recent springs I have ordered(not the firm ride, 1" lower type) were WAY WAY TOO HIGH. So I after I installed them, I let them settle for a couple of months(which they did) and then I cut them down with a cut off tool hooked up to my compressor. Once I got the hang of it, it was about a 90 minutes total to do the front end.

The ride firmed up nicely...the shorter you make the coil spring, the firmer the ride. Just be sure you take off only a little coil at a time, because once your ride height is to low, there is no going back...again I know about this first hand. I wanted to lower the car 2", so without thinking I took 2" off the coil...I think the car dropped like 4 inches...and I wasn't even drinking.

Ever consider going to a tubular front control arm? When I decided to replace the springs, I put a set on my 70 XR7 and it worked great in every regard. Hated that annoying front end squeak.

This is absolutely the very best source for springs. Not just a "one size fits all" supplier. http://www.eatonsprings.com/. Chuck

Agreed ..One the best upgrades especially if you get ones with the corrected geometry..I have them in my 71 Camaro & also did the upper & lower in the stang..The key is don't get the ones with the poly bushings..I have the delrin bushings in the Camaro & The street or track bushing on the mustang is a heim bearing with Teflon/Kevlar impregnated race

Which coilover kit was that?

What year Mustang was it?

Great job with the video. One day my garage floor will look like that.

That is definatly something I wil look into. Could you post a link for that kit. my other problem might be I still have drums in the front {I know I know} That is also on my list. I have a very long list like most of you hahaha. Guess you need disc brakes for that conversion. And as I stated I will have to buy new wheels and tires first so that is a nice little wad of money. {wheels are not final yet to many to choose from} But will be getting M/T tires for sure. I am planning on doing alot of upgrades But Budget is tight right now. Would just like to take for a few rides this summer.

So any links you guys send me will get me on track budget wise. just so I can see what things cost and make a decision from there thanks. Thanks for the inputs already given.
