Well time for a update, got the brakes all finished up. Started the truck, which was a win.....I thought. Noticed the rad sucked down 1/2 the coolant but no leak on the floor, tore off both heads no crack or no bad head gasket. Plugged of the water jacket and filled the rad and then had water pouring straight out of the oil drain plug
So guess I'm jumping a year forward and doing a LS swap gonna mate it to my SM465.
- Remove old turd
- Clean the engine bay up
- Drop LS in
I've ordered some mounting plates have a line on a complete 4.8 out of a wrecked truck, next thing I'm going to order is the LS to SM465 parts. Biggest hurdle will be finding a buddy with a engine hoist to pull the old block. Feel free to drop any threads on a step by step LS swaps. Appreciate any help, feedback
