Hey guys. Should I be looking at going to a scatter sheild instead of my stock bell housing. It is mainly a street car that may see the track a few times a year. Motor is a SBC making aprox 450HP (estimated). I have a saginaw 4 speed(I'm sure it will blow up before the clutch let's go) with stock bell housing. It should hook pretty good as I have mickey thompson drag radials 295/55/15

Please let me know if we need more info

If you have an aluminum bell housing,some race techs wont allow you to race. Its kind of like asking if you should buy leathers for a motor cycle that you only drive on hot days and its only 1,000 cc s

I bought a scattershield for my car.I doubt I will drag race my car,and it didnt cost that much. If you have a cast bell housing they are decent and would likely stop a disc.Ive never seen a flywheel come unglued. I remember when I was a teen and reading about Don Garlits losing part of his foot. I also use an SFI approved balancer. I just dont see any reason to cut corners with safety equipment.
Like you said though,the saggy will likely break before anything else. Have fun at the track,,,,

A friend of mine was over today giving me a hand and he was the one that brought it up. He has a new "tildon" (am I spelling that right?) Scatter sheild and throw out bearing (the kind that bolts to the inside of the scatter sheild) he will sell me for $300 which works out pretty good as have one of those cheesy floating thow out bearings made by Ram. It has already failed once and it has very little miles on it. I'm just waiting for it to go again.

JMO but I would go with the scatter shield. You already said it would give you a better throw out bearing set up and $300 is cheaper and more convenient than a prostetic leg :D. Plus you would probably stand to lose a few pounds if your housing is cast, but again thats just my opinion.

Here is the rule from the NHRA Rulebook, 2012. This rule applies to E.T. Handicap Racing, which is the type of class that 99% of the guys who drive in off the street will be in. This is bracket racing, so speed and E.T. are unimportant. Only thing that matters is cutting a good light and running on your dial-in. 11.50 and slower E.T. can use stock pieces, but you have to ask yourself, what are your feet and legs worth? I was standing in the starter box on the starting line at Firebird when an early Mustang fragged a stock, cast iron flywheel. It nearly cut the car in half. The flywheel busted into 3 pieces and the one that came through the cowl went several hundred feet in the air, then came down and landed just a few feet from the fuel trailer, which was in the pits, maybe 100 yards from the starting line.:eek::eek::eek: If I remember correctly, a small piece went through the side of the driver's shoe, but did not injure him.

CLUTCH, FLYWHEEL, FLYWHEEL SHIELD
Flywheel and clutch meeting SFI Spec 1.1 or 1.2 (two-disc
maximum) mandatory on any car running 11.49 (*7.35 in the 1/8 mile) or quicker.
Flywheel shield meeting SFI Spec 6.1, 6.2, 6.3, or 9.1 mandatory
on all cars running 11.49 (*7.35 in the 1/8 mile) or quicker. Cars with rotary
engines running 11.49 (*7.35 in the 1/8 mile) or quicker must be equipped with a
flywheel shield made of 1/4-inch-minimum-thickness steel plate
surrounding the bellhousing 360 degrees. See General Regulations
2:3, 2:5, 2:6, 2:10.

its a replacement bell housing made of steel.It has 2 parts,a big plate that goes against the back of the block.Some people leave that part out
Yep, those are the same people who fail tech inspection. When I get down on my belly and look forward under the car, I want to see bolts and nuts in every hole in the can. No exceptions. Those bottom bolts secure the motor plate to the can. No bolts/nuts, no motor plate, no pass.

I hate tech inspecters that count all the bolts.There are 2 bolts that are quite difficult to get in because of firewall clearance.

rules are rules though.I have all of the bolts in and all of them are grade 12.The grade 12 bolts have a nice colour

I remember when I was a teen and reading about Don Garlits losing part of his foot.
Actually, that was an exploding transmission that got Garlit's foot. He was experimenting with a 2-speed box and she grenaded on him at the starting line.
A piece of shrapnel flew across the track and nailed a 17 year old spectator in the chest/arm......

Timothy Daniel Ditt, age 17, with his fingers in his ears turned slightly to the left in anticipation of the final race towards the tracks end was suddenly hit on the left side of his chest and left arm that spun him violently around. Blood sprayed out of his left arm as it hung by only an inch of skin from his bicep. The shock of the sudden and massive blood loss from having his arm almost cut clean off had Tim screaming in horror.

The crowd around him cleared away from him as the spraying blood covered everything. A man ran down from the top of the stands and laid Tim Ditt down. Moments later another man stuck his thumb into Tim's armpit to slow the blood loss and save his life. Tim looked up at the man trying to stop the arterial flow and went unconscious.

Tim Ditt never saw Garlits' dragster explode, or the part that hit him.

In the 60s a good friend of mine ran a 58 vette with a '64 409 and M22 and had a nodular Iron bell housing,when he nailed second the flywheel sheered all the bolts and took out the bell, it came through the floor and took his leg off at the knee shredding his leg like hamburger! It bounced off the door panel tearing it to pieces and took his chin with it as it went out the passenger window and top! The pieces of the bell and trans took out his rear slick and tore off the rear quarter and half the rear deck!

It only takes one time to learn a lesson but when that lesson is learned its too late!!

wow! sorry pro street! I didnt expect so much in the way of death and destruction....
He still raced after that accident (automatics only) LOL!
Murphy's Law:"Anything that can go wrong will go wrong" There's nothing wrong with thinking things out!:mwink:

If I set a coffee on the edge of the bench and think man that might fall, and then think na it will be ok for a second my hands are full! And 2 seconds later (crash:eek:) After 50 years of those Murphy's Law moments you put things down and move the cup!!!! LOL We all have had those moments!
