Need suggestions everyone. I wanted to get as many opinions as I could on how I should go about upgrading my untouched 79 blazer. First the facts: 1.Aging 350 on it's last legs.Rebuild? New engine? 2.Keep the stock axles,sm465 and gears? 3.73 I won't be using it to mud race in or be a rock crawler. Just a good offroad rig. Here's what I'm wanting to end up with a dependable engine with enough power to run 35's on without it being a dog. Should I go with a stock GM crate 350 or rebuilt engine with a gear swap or a bigger engine without the gear swap. Whats the cheapest and most dependable way to go. My right foot isn't that heavy on the pedal. I'm kind of leaning towards the stock engine with a gear swap unless someone can persuade me otherwise. I'd like to keep the cost below $3000 Thanks for the help. Sterling.
