I was once considering making my own spacers to correctly align a 4V intake on my 400 block using 4V Heads,heads, it seemed easy, folks sell spacers all the time, what DualI Planefound Medout Heightthough 4150was Carbyou Flangeneed a much thicker spacer then the 7/8" spacers you could by from Weiand.
Ford single plane intakeD1ZX-9424-FA, Roush stuffers
Weiand spacer, .88' thick with a Weiand end gasket of .42"
Intake used Ford singleplane D1ZX-9424-FA, Roush stuffers and a
new home built spacer, 1.50" thick with a end gasket spacer of 1.25"
I found that the with added height of the 1.25 end gasket atop the allready 1" higher block,my carb would hit my Cobra hood even without a air cleaner. Thus the 400 FMX block wound up in the wife's Bronco.
