Are you sure you aren't thinking of the 5.7 Vortec? The 5.3 has a dry intake with no coolant whatsoever. (Composite)

The 5.7's were notorious for leaking antifreeze into the crankcase. Fel-Pro has a special gasket to address this.

I've got 220k on a heavily abused 5.3 & I have had no antifreeze or oil consumption/leak issues whatsoever.

I just feel that instead of modding up say a 15-17 year old truck, add that money to your initial purchase and hopefully get a newer better lower mileage vehicle.

It depends on which way I come out better. The newest Silverado I could afford would be a 2013 as long as I put down at least $8k and stretched the loan out past 60 months. That's assuming I don't get anything knocked off the price (which of course, I'm sure i could get some knocked off the price). However, it depends on how cheaply I could get the parts. I have a friend who's able to get parts pretty cheap. He told me the other day he could probably get me an engine with very lows miles on it for about $800. Sure, you have to include the cost of labor to put the engine in, but let's say I spent $3000 on the engine replacement on a truck I was able to get for about $5k. That' $8k invested. Maybe I beef up the transmission for another $3k. That's $11k. But, that's $11k on a Silverado that has an engine with less than 50k miles on it. You won't find a newer Silverado with that low of miles on the engine for that price.

It's all speculation right now though. Down the road when I'm able to pull the trigger, I might wind up going the newer route and just financing for a couple years. But, it's always been an interest of mine to have an early 2000's model Chevy restored and like new for much less than a brand new truck.
