The distributor location was a big factor in choosing this engine. By what I have read, the dist. is fairly waterproof. It is vented into the intake manifold.

They're not waterproof at all, and SOME of the later model ones were vented into the intake. It's a simple mod to do to a non vented one also.

Generally speaking Optisparks suck pretty hard. Especially when it comes time to replace them. ~$300 bux IIRC from my 4th gen camaro days. IF it were me, I would ditch that opti, and use a DIS coil pack setup. THAT IS WATERPROOF. Soild State, sealed in Resin.

Take some pics. U got lots of work to do.
