"Y" Block Heads - interchangeable parts?
The above pictures are of a Head from a 312 V8 "Y" Block Mercury Engine. Only the 272 and 292 Ford Y Block V8 Engines were fitted to cars and trucks sold in Australia. Are the Heads of the 272, 292 and 312 interchangeable? What about the Valves? My original Heads may be suitable for reconditioning, but if not, can we use parts from the 272 and 292 Ford Y Block V8 Engines? |

Re: "Y" Block Heads - interchangeable parts?
Yes all can be used on the different size engines (except the early 239 heads). In fact there is no such thing as a 272, 292 or 312 specific head (except for maybe the supercharger heads). The same head would have been used for all Y-Blocks of a certain year, i.e. the ECZ-C heads you have were used in 1956 for 272, 292 and 312's.
As far as parts being interchangeable between heads you will have to check valve sizes as the different heads used various size valves. And of course, heads should be used in pairs as different castings have different combustion chambers and compression ratios. Check here for casting numbers and use; http://www.ford-y-block.com/cylinderheadchart.htm Last edited by Y-Blockhead; 08-24-2015 at 11:52 PM. |
