Similar to the TR1 Edelbrock BreadBox this is a half custom cast half fabricated piece Ed Shartman is claimed to have tested. The quality is on level with a modern sheetmetal tunnel ram but it has the proper look of the time. This is for Boss 302 but there are spacer plates that would allow it to be used on a 351Windsor block with Cleveland heads or an actual Cleveland. And yes those spacers would be specific to each. *** Now for those scoffing at the title ... With the FE it can be used with the vintage Pro Stock Engineering Black Widow intake adapter or Jay Brown's current version which mates the Cleveland intake to the FE Ford. You'd need the spacer above but it bolts right on which ever wedge head you choose. My intent was to run it on a Black Widow for Hiriser which is pretty rare in itself, add a 1 of 1 tunnel ram and it ought to raise a few eyebrows. 33o-8for4-six37o, Dan
