so after some thinking and listening to others, I will be buying a crate engine and new transmission to be put into the corvette.  I will also be keeping the engine that is being pulled out.  I believe it is the original engine.  I have only owned the corvette for one year.  So I do not know what has or has not been done to the engine.  This way I will know all about the engine and will be able to have a warranty with it.  Thank you all for your advice.

Good plan.  👍

Good luck, I ordered a 355, 300 hp crate from Jegs back in April. Was told end of October. Hope you have better luck. AKT I believe do the crates for a lot of the sellers and they say they just don’t have any blocks and parts to build for awhile. 

You might try getting a crate engine from Chevrolet as they have several performance ratings and a 3-year warranty.

I've also heard good things about Blueprint Engines.

I talked to a place in my home town and they said they could build me one in 6 to 8 weeks.

they company I talked to has a 7 year 100000 mile warranty.

How does their cost compare with the Chevrolet crate engine?
