Hi guys,
actually I plan to rebuild my 239 Y engine of a F100 1955. Unfortunately the block have a ecg (272) casting number all other parts, heads, intake, headers the correct EBV (239).

At bying the F100 the engine not runs since 20 years. I belive this mix would work, but not very well. The intake will not get enought air in the cylinders???!!!

The best way would be, to find the correct EBV engine block. Any folks out there who have a rebuildable ebv block in the garage???
