swapping 12v block into my 24v
 

Long story short the block that was in my truck was garbage 53, its a ppump 24v and im putting in a 12v block theres no cam sensor since its a early 98 24v so the only problem im going to have now is trying to rig up a crank sensor for the tach and for the charging system to work, I see destroked sells one for my truck the 36-1 tooth tach kit, has anyone tried using one before, how dos it work does it plug right into the wiring harness or what?
