We are in the business of getting cars done. We have completed MANY LS conversions over the past couple of years. If all you need is a motor/trans conversion, that is pretty simple fare. If you need more done, we can certainly accomodate- in a timely fashion. Advice is free, and maybe we can help you source an affordale transplant whether or not we do the install.
The guys at CAR are good people and could surely get you dialed. Most people here on Lat-G are stand up guys & stand up shops....but always do your homework. A good, reputable shop has nothing to hide.
You're not the 1st to go down this path. Whichever way you go, you will LOVE the LS platform in your car. My almost daily driven '68 Camaro conv't sports a MagnaCharged LS2 w/ 5-speed......best thing since sliced bread!!
Good luck in your venture!
