I think most would suggest to stay with the same brand for the powertrain and body.... It's going to make your build go a lot better....

If all this is still in the planning stages, might also want to consider one of the Camaro's with an LS engine in it... All the necessary parts are available from the aftermarket to do the conversion and when it's done you'd have a car that has good performance, decent fuel mileage, and better resale???? Just another consideration.....
