Title: Fox .35 Number 2 head question.
Post by: frank mccune on July 27, 2014, 12:46:11 PM

     Hi:

     Years ago, I picked up a package at a flea market marked Fox Number 2 head for the Fox.35 Stunt.

     I have never heard of this head but once when a friend of mine saw it he said,"That is a Fox number two head. "  I used it on a Fox .35 Stunt and did not notice any difference in it over the regular Fox .35 head.

     Has anybody had an experience running this head? If so, what were your impressions?

                                                                                                                           Tia,

                                                                                                                            Frank

Does it have a baffle slot?

    Hi Doug:

    Yes, it does.  The head is a "high compression" looking head with a lot of metal filling the combustion chamber!  I have not tried it on FAI fuel but it might work very well for that application.  From the outside, it looks just like the stock head.

     This must have been made available in the mid-late 50's.

     As I said before, I did not see any power gain by using it!  It may have been a determent to having the Fox .35 Stunt perform well as stunt engine.

                                                                                                     Stay well Doug,
