XF/GL Engine Rules/Possibilities???
« on: February 16, 2015, 02:52:14 PM »
So,... I have a rule book (wife just moved it though,... drat & double drat),... thought I'd ask a few questions to check my sanity about my '51 flatty build.

What is the max displacement bore/stroke allowable in XF/GL?

I understand that no special overhead valve heads are allowed(ie: ardun, etc...),... what is the limitations(ie: can you build your own) on building a head that keeps the side valve set up within the engine block intact?

must the valves be operated via camshaft, or can they be opened via solenoid?

Would a desmotronic set up be allowable, if it could be fashioned?

no huffers or turbos,... got that ,.... fuel Injection seems to be allowed, what about intercoolers, seems I remember no chilling the intake etc...?

Appreciate the help fellas.

God Bless & Godspeed,

Sean

A desmo flathead! If you can build it I think they will let you run it. Yes you can make your own heads. I don't know why an intercooler wouldn't be legal. The solenoid valve deal I don't think would fly. To much like EFI and F1. There is a contact in the book for answers that are worth reading.

   The XF engine rules do not state valves must be operated by the cam but remember the class is called vintage however that question should be directed to the SCTA official in charge of the vintage engine class contact Mike Stewart     m.stewart46@yahoo.com  
   Superchargers are allowed in the XF class there's no reference in the rules to chilling or intercooling not being allowed.  Any ignition system may be used and computers are allowed for data collection purposes only.  
   The following are not allowed in the XF class Turbochargers and Electronic fuel injection.   :-)

"...For reasons of authenticity...USING VINTAGE BODIES"  which I read as meaning it's legal in non-vintage (ie, streamliners and lakesters) bodies.

But check with the authorities.   :cheers:

Mike has a turbo, EFI, V4F/GL. So I guess you are right about turbos in Lakesters. I had a turbo GMC/Vega in XO/BGAlt. But they would not allow me to run it in my 32.

Different rules pertain to running flatheads in Special Construction and running flatheads in Vintage classes. See 2.A.1 (especially page 20, 7th paragraph, 2014 Rule Book.

Wow, lotsa stuff,...

Ronnie- Just to clarify XF/GL would be "normally aspirated, vintage, flathead, gas, lakester",... so the supercharger is not an option,... correct?, thanks for the contact info. I appreciate the no efi clarification,...

any ignition,... soo then,... crank triggers & coil packs are cool, yeah?

Rich-Thought was that the desmo would eliminate the whole valve float deal, though it may not be worth the effort, wanted to know the answer for curiosity sake. good to know on the heads for sure!!!

Stan-Thanks, will see what I have in the 2013,... if you know there is adifference in 2014 can you post that here?

Mike-My body is an aluminum Hell Cat Belly Tank

thanks again fellas
