Can anyone tell me what the W1 or WI stands for on my 428 block. It's from my 69 GT500(#1960) and the block was made March 21, 1969 and car was built April 21, 1969. http://www.bsalscars.com/pic.asp?strMenu=engineDate&strLargePic=1969ShelbyGT500/pics/9c21_driver_engine_800x600 Thanks
Hi folks! just my 2 cents worth. F E engines were final assembeled in the Lima Ohio plant,which still makes V6 engines.They could have been cast in the Windsor plant,then sent to Ohio for build.Does anybody out there work for Ford??
