I know this section of the forum is for BBF engines but I have a couple of questions regarding front suspension parts. I already have a rebuilt & modified 460 in an XB coupe and i am progressing with this project in slow time. I heard there was off the shelf front springs in varying heights made for this type of conversion anyone got any info?. Also after slotting in the engine the swaybar fouls the oilpan under brakes. Pan is a Bandit aftermarket unit although the pan is not the issue. has anybody else struck this problem. Can't remember the maker of the engine mounts.

Any info would be great.

The problem of the sway bar is solved in 2 ways which i have done..The first one i did was to use a high-energy sump which has a 45 degree chamfer on the lower front edge of the sump.
The one you would be interested in is to take the sway bar mounts on the chassis and redrill the mount holes slightly forward of the original holes.The whole sway bar then moves forward and the links on the lower control arms stand upright a little more as opposed the sloping back as std.
Make up a piece of 2"x 1/4" steel plate as a plate on top of the mount to 1.strengthen the mount point a bit and 2. cover the old holes.
Once it's done you have to look hard to tell the difference.
On the springs i have used the pedders coils for a cleveland..
I then move the battery to the boot and use an alloy intake on the B.B and the weight of the bigblock wouldn't be much more than a clevo with all cast iron intake/exhaust manifolds with a/c + p/s..
Hope that helps..

Thanx gregaust,

will relocate the bar as suggested. I still have all the info on the C4 mods you sent. the OEM b/housing proved elusive am going to have too get an ultrabell...........gulp!

gregaust

Hope it all works out well..I see those BB/C4 bellhousings on ebay from time to time ,one day i might get one..

XBHardtop

have checked out the pedders and lovells sites have you used these brands?

gregaust

Yes,have used both.Pedders with the big blocks.

i also have a problem with the C6 which is leaking fluid. it doesn't appear to be from the pump seal or the pan seal but a lot of fluid is leaking from somewhere while the thing is just sitting there. have heard about the converter draining what causes this?

gregaust

You will always get convertor drainback.It's just the higher level of the convertor equalises with the oil in the case..As the level in the case gets higher it could be the dipstick tube o'ring or the kickdown shaft seal..

sounds like a good place to start ......thanks.

It must be something with 460 / C6 combo's in XB coupes, mine does exactly the same thing!!

At first I thought it was the pan seal. I replaced it with a new rubber unit, but it still lieaks when sitting still! (I'm spewing I didn't weld a drain bung in the pan when I had it off the first time)

I suspect that it leaks though the pan bolts. ie: If the bolt holes are not blind / captive holes in the casting and they actually protrude into the liquid area, I suspect it leaks down the threads of the bolts???? I can't see any other way. I clean the tranny, drive it, park it. Re-inspect a few days later and there's fluid all round the pan.

BTW. I put 10mm spacers under my sway bar mounts to get the clearance to the sump and use pedders springs / shocks successfully.
