4 cylinder conversion weight question

IM just curious about is a 4 cylinder mustang thats been converted over
to a 302, will it be lighter than just a regular 5.0? Its just a stripped down base model, only power locks and mirrors. The windows are both manual. No air, no smog. Remember these are completely stock cars, no mods. But i was wondering that, if a 4 cylinder coverted mustang is lighter than just a factory 5.0 with the same options, can you understand what im asking? Any replies will help me alot.
 
If it is, its only because you're missing the power window motors. From what I've seen, stock 2.3 LXs are around 2900. A 302 has at least 200lbs on the 2.3 and the 8.8 rear is a little heavier than a 7.5. A fully stripped, and I mean gutted 5.0 gets back around 2800lbs.
 
actually, it may a little lighter than a smiliar-equipped 5.0.....
aren't the anti-sway bars and soem suspension items heavier on the V8's???
i'm sure, if there is, its not a significant amount at all
