new Front springs or ?

[pabear89]

.... Well I'm stuck on this one.
I have a set of Big Block springs that I removed less than a quarter of a coil from when it had stock spring perches on it and it rode like a lumber truck.

I replaced the perches with Ot's roller perches and it did allow spring movment plus a whole new handling and ride,the front came down about 1in also
and it looks good.

Well......It seemed that the engine had some oil issues, it started to drink a quart in 75-100 miles.

But on the plus side it gave me an excuse to pull it and throw on some of the parts I have been collecting.

While I thought that I might be losing some front weight by removing the cast parts and replacing them with alum peices it seems that it gain a few pounds more.

Now when I pass over a swell in the road the headers smack the pavement when the front comes back down.
I know they are a slight bit lower than the stock exhaust (the lower tubes hang below where the old pipes were) but they never hit except if I took a steep driveway too fast.

Now some say that cutting the coils make for stiffer spring rates,
but this is not happening here.
Should I buy a new set of stock BB springs and replace them?
Or Will a pair of 1in poly spring pads make up for the drop and travel.

I need to do something before I have a set of flat lower tubed Hookers.

Any Ideas fellow stanger's?

I`d try the spacers

I got a set 3 feet from me just waiting for the chance to jump on my car. Cheap fix too.

Did you change your motor mounts in the process? Might explain the engine sitting a little lower.

Cutting the coil DOES increase the rate. Period. All a coil is is a spring bar wrapped into a coil. When you cut ANY length from that bar you increase the rate by the % you shortened the bar. It may not seem like it with the new roller perches but it did indeed increase the sring rate.

Kinda off your subject, but what brand r&c are you running? Is it on the 70Mach1 are you happy with it?

Thanks

Me LIKE Cheap!
But will it just be a bandaid or will it really help?
If I have to take out the springs I only want to do it once.

No the same mounts are in place.
and the exhaust pipes went into the collectors with only widing the x pipe some.

I knew it went back togeather too easy.

If that is true, these 800# BB springs should not have as much give with this 351Cj in it. unless the extra weight of the scattersheild is pushing the weight up to BB size.
