Really?
But anyway, the right way to fix this problem is to NOT have fire in your intake! You should never, ever have fire in your intake!!! NEVER!
This comment makes sense. I blew up a Magnesium Hemi Crossram that had the lid raised 1" It turned out the cars owner had lashed the valves wrong and it hung an intake open. The thought about the ignition firing when switched on is an interesting theory. No fire should yield no explosion.
Did you have the throttle blades open? The fuel came from somewhere. Were the throttles pumped during the blade repair? No blaming here just trying to determine the cause. I had one of the very early manifolds. Never had a problem starting with the throttles open. New engine will have one as well. Doug
