Ok this is an odd one. I put a stock 4-v intake on my '75 truck. I'm going to run an Edelbrock 600 CFM carb with no spacer. It cleared on a 400 with an EGR blockoff plate but wouldnt clear the EGR valve on the smallblock.

Can I lop the top off the valve and have a makeshift blockoff plate? Or, will I simply need to find a factory blockoff plate?

I'm in need of getting this thing on the road because its my only mode of transportation right now.

any reason you cant put a carb spacer on it? seems to be faster, and easier, and if you go phenolic, it might help your performance

I would just remove it and find a piece of flat steel, drill a couple holes in it and make a gasket for it and put rvt on it and bolt down.

yes,knocj the top part off and leave the base bolted up

done a bunch like that

i take a cut off tool to them,only takes a second

Thats what I did, pried the top off and took bolt cutters to the shaft. Ugly now but it works and the truck runs much better. Eventually I'll do a plate if I make the motor nice but not now.
