QT bell on a FH

[HNORD]

From what I had read, the Quick Time bell housing is not legal.
Normally the QT is SFI and ok for Nascar, NHRA but rule say on landspeed rules if ”nothing to bought” it’s Ok make a own in steel 1/4” thick.
The QT is said to be twice as strong as the ex Lakewood.
Even if QT has a FH bell its not SFI ( according to Speedway M )
My guess Holly did not bother get them to SFI, but it’s shore the same bell design as for ex a Chevy at SFI.
I has ask Speedway on material and thickness and they don’t know and told me to ask Holley.
I did try today, but no luck.
At SCTA tech they mean if steel and 1/4” it must be Ok
That’s my thoughts to.

Ideas ?

It's pretty easy to ask SCTA officials for the correct answer to the question.  Start with the suggested Car Technical Committee Chair, which is Lee Kennedy.  His contact info is in the rule book.

I has no rule book yet ( just the online from Australia ) as the SCTA web can't sell the rul book ( just now )
I talked to tech yesterday as it's confusing.
I know the rule, so SFI or a home made at steel 1/4" thick, but I see no reson get a Chevy SB Lakewood ( less good ) bell when QT make one for the FH.
As Holley sell the bell for QT, I has try ask them ( no luck so far and Speedway can't either get a answer what material and thickness QT use )
They say on add it's twice better than a normal steel bell, but is it at the rules specs ?
That's the question I like to hear.

Forgive me - you'd said that you did not a rulebook, so of course you don't have contact info.  Lee Kennedy is Chair, Car Technical committee.  His email is lee.kennedy@avmetrics.net 

I'd be glad to ship you one of my copies of the 2021 rulebook.  Please privately send a mailing address that I can use and I'll post the book today.  I'll find out the postage fees and you can Paypal (or something) the fees to me.  The book is yours free.

Thank's.
I can order the rulebook in 2 weeks the SCTA told me yesterday.

I found info on the web on contacts.
I has try mail before but yesterday I got contact over phone.
I will try again to call Holley as SCTA can't know how Holley did this FH bell ( and material & thickness ) so no rulebook does help me here.

In this video QT and ( Holley ) show the bellhousing manufactoring.
Look to me 1/4" thick and press lathed.
I can't get hold of Holley even if they say in this video 'just contact' them.

What I can read is this ;
Built from high grade steel - Work hardens to over 80,000 PSI strength. Over 2 times the strength of any other steel bellhousing.


-So to fit the rules it needs to be 1/4” thick.
I guess that, so I cant see any problem here.

Committee is checking this out now ( let's see )
Quick Time will problably not get this bell at SFI but it's made the same as rest of them.
This is strong bell housings and lighter than a Lakewood.
It was years I saw a NHRA racer used a red Lakewood now, as all stick guys use QT ( they also has a spun alu that are at SFI )
I has a QT Chevy here now and the parts against engine is at 0.32" but the bell section is at 0.17" ( not 1/4" ) but as they is spun lathed they get it stronger than 1/4" steel.
It don't make sense to me get a Chevy SFI/Quick Time or a Lakewood and go over that proocess to get it to fit ( and then be legal )
Let's see what committee says.
If Holley/QT sell one for a FH it's more safe then a homemade one at 1/4".

The QuickTime flathead bell housing is advertised as 1/4 inch thick this is legal then for use on your vintage engine. As you know one could also build their own enclosure that as long as its 1/4 inch thick it would be legal for the class. There should be no openings where the contents can come out so if there's any windows say along the rear surface of the quick time that area needs to be closed with 1/4 inch thick steel. The area of the clutch fork is the only area where a complete enclosure is no required since the clutch arm needs to move for the proper release.

I got this now from committee.
They notioce this at Summit, se below.
Strange at Speedway and other sources it's told not SFI.
I guess cover the holes and that is it.
