    Last pic is old overhead system & how we oiled the 487 along with a Peterson wet/vac pump .
    The rear feed was switched from out of the back to # 5 main . An external balance line ( -6 )from off the oil filter outlet to back of block .
    We had a main external Manifold feeding -6 to rear , -8 to oil sending front -12 to front of engine passing under Intake into a -8 the Three way manifold Block .

    New manifold full is -12 under intake & will & should support 3 center mains & exit to rear of the lifter valley to stabilize #5 main & 8 rod
    Mind you we run a 3/4 bearing with 2 extra holes & channeled mains
    New SRE Dry sump pan & a dry sump Daily pump.

    This has been a modification & discussion that has not been up dated or died . Or at least I haven't read or seen in a long time .

    Maybe the moderators can merge this with the old thread or make a sticky ?

    There was a lot of good information about Keeping the BBB alive in the old post .

    For those die-hards who still run a serious 455 Iron race engine , here is the oiling & modifying that we do & has not been discussed in a long time lol .
    Hence the release & most upgrading to the TA Tomahawk.

    Looks like a plumbers nightmare, I believe the rear oil line does a much better job through the fact that there’s not so many bends and fittings that causes restrictions . But to each his own .besides The T/a block resolved all those issues. I would bet by the time you girdle epoxy brace etc. and do all that work you’re close to the price of the block anyway

    Not if you do 90% of it yourself.

    Don't forget about the TA blocks machine work you need to do before you put it in service.

    Oh I know I’ve done quite a few myself it’s just not worth all the effort and in the end you don’t have a reliable block for that kind of power it becomes a safety issue. And besides I don’t know too many people that are able to install girdle which is the most expensive part of the upgrade. Not to mention most shops can’t do it correctly anyway. 650 hp and under your fine with a select iron block anything after that it’s just a matter of time !

    Ben, why don't you just send it to Gary pain and have his machinist install the girdle.

    Here's some pics of a system that was developed in the 70's and used on a local circle track here in Flint. Not sure if it was a KB system or home developed. The guy who ran the car was a Buick employee in the shop and ran a machine shop at his home.

    I'm trying to see exactly what you have done. The three interior mains are fed through the valley, where does it enter in the block? At the cam journal? The outboard mains are fed from the back oil gallery hole. The front from the normal oil feed/pressure hole? Trying to follow your hose routing, can't quite do it.
    Thanks Rick

    Does anyone know the earliest that KB started selling the block girdle? Dave Hemker's block has a girdle and
    as you can see by the oil pan, the girdle doesn't even go all the way to the ends like TA's does.
    I was wondering if it was home built or KB's? I know this motor was built around '77 or '78.
