Just a thought...but if you were to drop and LT1 350 w/ aluminium heads,  and use modern gm fuel injection and of course turbo hydro trans (which would make the swap a lot easier than trying to mate a toyota trans), you my friend would have a hell of a daily driver.  Any weight gain would be negligable , if there is any weight gain at all.  
Side note: If it were me I would keep that puppy looking as bone stock as possible on the exterior. What a sleeper!:eek3dance
