whats up guys, i pulled my 350 out of my van and its filthy! its covered in oil gunk, all over. i took off the carb and the intake manifold,today i cleaned the manifold, but what would you guys recomend i do next? should i have the whole engine hot tanked then coninue to take it apart? also, i want to replace the engine i have with a new long block, so i was thinkin of selling the whole engine to a automotive place, what might i get for it? (something in the core is recked, piston, or push rod) so pretty much what i want to do is keep the carb, intake manifold, and the distributor and swap them on to the new long block, and i want to put headers on it too. also, i want to redo all the electrical in the van, the engine is out, and the tranny, so everything is out, where do i start to redo the wiring for everything? do i just rip everything out or how do i do safely so i dont miss anything i need. everything is going so where would i start?
