On my '81 302 intake manifold there's a port that connects the exhaust crossover to the EGR passage on the spacer. I've converted this rig to a MC 2150 (original: VV 7200) and have removed all emissions gear excepting the PCV. The EGR valve has been removed & the spacer blocked-off at that end. Is there an easy way to block the opening on the int. manifold so as to keep the hot exhaust out of the spacer entirely? It looks like an intake-to-spacer gasket for a 351M would cover that port, but I'm not sure it would cover the casting in the spacer since their's a "bulge" on the pass. side of the spacer where it mates to the port in the intake. Did that make sense? If there is no gasket available that would seal the perimeter of the spacer but not have a cut-out for the EGR port, is there another method of blocking that port?

As long as you have the valve blocked off, exhaust gas won't get into the manifold. It won't have anywhere to flow to.86 Lincoln Town Car (Galactica).

Yeah, I get exactly what you mean about the exhaust having nowhere to FLOW to & that's probably half the battle. But with the manifold port open, won't it just keep pumping hot gas INTO the spacer and transfering a good portion of its heat to the spacer & by extension the carb & the intake charge? Seems like the spacer would just end up acting like a big heat-sink, soaking up heat from the exhaust gas that keeps being pushed into it & then trying to dump that heat off to the carb & the int. charge as it passes through it.Comment
