Interesting topic,i always remember the top place getters in the 1967 Wills 6 Hour being stripped down after the event,everyone had a fully port and polished head,the excuse was ,rules said you could balance engine parts and all they did was balance the combustion and exhaust chambers.If they had chucked them out there would have had to have gone down to 4th 5th and 6th place !!!!!

Pretty much all somewhat other than the rules required back in the day. Back to front pistons, some "slightly" oversize engines....
Yes i know of a gent who raced a xu1 and he said he did that with the pistons also.
Back to front pistons....May not have been illegal
It happenned in GTHO Ph3 engines in 71
Section from Ford memo on the QC engines dated 8/4/71 (This is prior to the HO3 being released in May)....
