Last week I was given a free LT1 aluminum head 5.7 out of a 95 Trans-Am. I knew nothing about the motor other than the "fact" that it "ran when pulled". I got it up on a stand and started tearing into it and found... well I found issues. I really got my hopes up when I took a look at the top end. This thing was CLEAN. Not a spot of gunk or grime. Intake runners in the heads looks like they had barely even been run. Much of everything else top end was the same. Barely run. It was all fun and games until I pulled the oil pan. That's when the 'ol heart dropped right into my shoes. Yikes! Babbit material for SURE. Long story short, I've got 3 spun rod bearings. One so bad it had actually worked one bearing shell into the other. NOT GOOD. The crank looks like maybe it could clean up, but obviously the rods will need to be looked at too. So here is the thing. Do I look into grinding down this crank and the rods and run what I have, or should I look at a new crank? I see Eagle cast 5.7 cranks are less than $200. But I'd still need Rod work done, not to mention balancing. The other option is to throw caution to the wind and pick up a kit like this: https://motorsportsunlimited.com/lt...draulic-roller-camshaft-choose-options-below/ The nice thing about this is that it provides pretty much everything I would need to get the engine running again (besides a carb swab intake and associated bolt-ons) and is within a couple hundred bucks of what I estimate it would take to bolt this thing back together with the OE crank/rods. Plus it's a 383 set up which would be SICK. My price comparison is assuming new timing set, cam, bearings, rings, etc would be needed. I don't know what crank/rod machining costs, but if it's any more than $2-300 the final price would be right in the ballpark of this all-inclusive kit. So I guess I'm just throwing this out there to get ideas. I've never built an engine from the bottom up before so I want to make sure I do it right. Plus I don't really want to have to do it again. Since I'm into this for $0 so far, I figure building up the bottom end a bit would be worth while. I'm just really glad this thing was free!
