I am looking at buying a LT1, and was wondering if anyone had tips on where to look and how to make sure you're getting what you paid for. How can I be sure that an engine is still in good condition, and are there any specific questions I should ask?

Thanks

 

check the casting # on the block and heads ..

When I got my vortec 350, it was on a stand, I told the guy I wanted to see in turn ..the harmonic balancer has the 3 bolts, so valve covers off.. he put the pry bar in between the blots and I could see the rockers-springs compressing ..

dont know how much insurance that gives .. as the engine could need an overbore .. the only way to be sure is to have the engine apart, then inspect\mesure the cylinder walls .. combustion chambers (blueprinting)

Hope this helps , others will shim in im sure

 

If you can't see the motor in person that you will have to take a risk. Have the seller send you all casting numbers so that you can varify the engines identity. Chances are the more complete the motor comes, the less likely you need to have it rebuilt. Running motors are often sold with everything you need to make the motor run. If the motor is bad the seller typically parts it out and sells that bad part as a core. I would expect the worse case senario though and expect to have to have the motor rebuilt. When you have the motor in your hands you can tell for sure if it is good to go.
