In response to earlier post's on this thread, I read that Ford cast some mixed nickel engines, very few, 428's for their racing team in 1968, and a few of these engines made it to the public. I have read where some of these engines have sold for quite a bit of money.
Please see the below pic's of an engine I own, the rear of a ford engine block.
I am having trouble identifying the XX scratches on the right side of the block, & the #17 on the left side.
I beleive it to be a 428 due to the
oil ports being plugged as well as a "28 DIF" stamp on the passenger side of the block, (not shown here), the extra "Blind threaded plug" just above the
oil pan passenger side, It also has a single "S" stamped on the bottom of the
oil filter side adapter.
The block cast number refer to it as a 68 390fe Galaxy, which I don't beleive to be true, due especially to the oil port's being plugged as seen in the picture.
I found a post that claimed the XX's were scratched on the engines that were for the race team, but can't find anything else to substantiate that remark.
Any help would be greatly appreciated.
Thanks'
