Back to the Holden and Ford thing, I bet that Holden whatever is running a FORD 9"
so why stop there. I have a friend here in tassie running a VB commodore EX commodore cup car running a Ford 351,toploader and 9" diff.
We call it a forholdan.
The car runs a 11.9 over thequater, has one neally every burnout comp, and does a 1 min 2 around simmons plains (Tassies race track) i think the V8 supercars are doing a 56 sec.
Not bad for a complete home build.
