So Im planning on buying a rule book, but I have a few questions I was hoping some of you could help me with, as a few friends and I are contemplating going to the salt next year. If I run the V4F class, can I also run the V4 class? Must you use a vintage transmission as well? Can you use insert bearings? Are their any restrictions on rear end configurations? We are looking at the V4F/BGL class, so appearantly we will be competing with some fellow HAMBers. Thanks for any help!
we ran a T5 in xf/vfalt. I haven't looked at a rule book for a while. the rear end was a 9". hope that helps a bit.
There is a rule in the book that is called "lowest primary class". This means if a class, V4F, exists you must run that class and cannot run the same configuration in a higher class. Now some may think that the V4 classes are not that high, its all relative. Trans, rearend, etc. are free in the Gas Lakester class. Good luck, DW
You need to put an OHV conversion (or use an OHV engine) to run in V4. If it's a flathead it will run as a flathead. Note that there is no requirement that it be a Ford engine. Plymouth and Dodge engines have been run with some success as well as Chevy fours in V4. Other engines may well be a good choice for the class.
American made pre 1935 four cylinder. V4 can only run in vintage classes or special construction(streamliner of lakester) V4 is with any special constructed overhead valve head. V4F is for flathead 4 cylinder engines.Max displacement is 220 cubic inches
I believe the design origin needs to be pre 1935 for example you can run a 1940 ford block in the XF class because the design is still identical to the 35 block although the french blocks have been outlawed. Also I thought that the V4 class had to be a flathead block converted to OHV. The rule book can be a bit confusing.
THIS IS WHERE I WENT WITH MY QUESTIONS. GREAT GROUP OF GUYS AND GALS http://www.landracing.com/forum/
I believe the V4 rules are very clear and easy to understand. The block must be a pre 1935 American mad four cylinder automotive production engine. Not a 1940 replacement block or Russian block or any thing else. This has come up before and been well sorted out. I also see nothing at all in the rules that would indicate you need to begine with a flathead and convert it to OHV to run in V4. Chevy four cylinder engines can and do run in V4. Try not to read things into the rules as you would write them. Makes to much sense. KrisKustom seem to have XF and V4F mixed up
sorry, i have no experience actually running in that class. I didn't mean to cause any confussion its been a couple of years since I looked into the V4 and V4F classes.
It's a good class to run in IMHO. Fooling with old motors makes me feel like a Hot Rodder. Not as many plugs to change is also a good thing.
