I am getting a newly forged fully built engine that is a 370 ci. I am not sure, but i am guessing that its an LS2 block. I mean they don't make a 370 LS1, right? Anyways, I hear that the more cubic inch, the more it affects gas mileage. Is that true? It seems like it could be. I mean i am looking to still make my car mostly street legal and friendly. I would guess a 408 iron block would be too much for what my needs are. Plus i plan on using the STS rear mount turbo. I hear that setup works better some how on smaller cubic inch engines. Not sure if that is true or not.

Most importantly, What the hell do i do with the old stock engine once i get the new one installed? I mean what do you guys do with your old block or engine? I almost wouldn't want to part with it so if something happens after a while with the new one, i still have my old one to use. Does that make sense at all? But my mechanic is going to install the engine. Should i ask him to take the stock engine apart to the point where its in pieces that i can carry by hand or should i invest in something that holds an engine or what? I'd really appreciate some insight on this.
