221 crank was a stroker option only the thrust was on the wrong main.. number 7 on the holden number 5 on the ford from memory

hard pressed to get a 221 these days, all the ford guys want them. i know, as, i want one as well

better to get get a billet turned up anyway rather than 'welding' the two together ... albeit welding would be cheaper

I have some pics of that black FJ. Took them at the Shannons day Eastern Creek. Didn't Brock fit that Chevy 6 into an Opel. Should have some pics of that one to.
