loosing some weight

[rubbinsracin]

how much weight difference is there between a steel bellhousing and a stock GM aluminum bellhousing?

trying to shed some weight.

also, can you turn an underslung car into an overslung car simply by cutting the underslung parts of the chassis off?

[latemodel86]

I'm not sure about the bellhousing part of your question. In my opinion, the underrail cars are better and I wouldn't cut the frame just to shed weight. Yes it may be less room to work on the rear end of the car with it being an underrail, but it makes it a helluva lot stronger than an overrail. JMO

if you cut the under-slung it will weaken the rear structure of the chassis,...the steel scatter shild bell housing is a safety issue an you probably got rules bout having to have it....good luck

off the top of my head, the Lakewood bell with post is 42 pounds, the stock is 8, but the steel Quick Time light weight bell is about 20

You are really asking for a mess if you cut off the underslung portion of the chassis. The overslung part is not buitl to be ran without the underslung and is not as stout as a strictly overslung car...Ton's of places you can lose weight, Ti bolts, mag hubs, make the driver go on a diet....Cutting off the underslung is NOT one of them.

Lol sorry guess I should have made that two different posts. I wasn't looking to loose weight by cutting the frame. I just simply wondered if it could be done. when we go to an aluminium bell we would run a scatter shield.

What are you running? A late model or modified running a Bert/Brinn/Falcon does not need a scatter shield.

[Egoracing]

anybody that runs a stock bell is asking for big trouble...

get a steel bell and forget about the weight issue..

unless u have late or a mod then get a brinn or bert type bell,
but these will break/crack also...they'll last longer than a stock one..

them stock ones will get body parts broke!!!!

tail brace or not, stock bells are junk.

The guy that I know that kept breaking them was on a 362ci aluminum head alcohol motor. He got REALLY lucky and found the trans unger the car on the trailer hanging by the shifter arms one Sunday after he got home from the track. He was pulling on an open trailer, it would have been REALLY REALLY bad to loose it on the highway at speed with other cars around.

As long as you have alignment good and do not forget the bellhousing to block allen bolt behind the starter, you really shouldn't have much troubles with a Bert/Brinn bellhousing. We've had a Bert that was repaired due to the previous owner forgetting the allen and have ran it for 4 years with zero cracking, and I'm talking some ROUGH motocross whoopdie doo places in a DLM...

On the topic of saving weight, this is a trick that many use.
Instead of using lock nuts on all of your bolts, use the jam nut style nylon insert lock nuts. They are lighter and they also will allow you to cut the bolts down to save even more weight.
There is a lot more weight to be saved by trimming bolts down than you might think.

stock bellhousing will shatter and your trans will fall out the bottom of the car...lost a new ballspline going down the straitaway in a late model before we knew better....We use the Winters Bellhousing..No problems for 3 years...
