I have a chance to grab a 4.2L from a budy of mine and I have a 4.0 block that I had laying a round that I riped out of my XJ, I herd that u can put the 4.2L crank in the 4.0L motor to strock it. is that true and will be worth it.:rof:
 
You package it back up in the box your bored out throttle body came in, and send it back as a core.
 
If you don't have the tooling to do it, you would be better off buying a bored out throttle body. They run just over $100, and there is usually a $100 core charge for your old one.

If you have a spare to send in, no downtime.
 
Watch ebay for bored throttle body's from a guy named "artsound".

Otherwise, "Jeepers and Creepers" in san francisco does them mail order.
