Random questions!
Ok so dont shoot me if this is the wrong area to post this!
But, all this time I have had my car and brag about it to everyone I always get the question, "What size of engine is the LS3?" So other than saying its a 6.2L V8, how big is it? 350? 375? 427? cause I rele dont know! |

I believe so. I know GM Performance offers the LSX 454 so between that and the LS7 which is 7.0L there's definitely room for expansion.

It can be bored some, but I think getting it out to 7.0L, or out to a 454 (7.4L) takes more than just boring. Some special work needs to be done with sleeves to get to the LS7's displacement, and that's both boring and stroking.

I'm really noobish but, what does it mean to bore or stroke an engine? And what is the purpose?

Quote:
Stroke= the distance within the bore that the piston actually travels. Boring and stroking = making the bore larger and the stroke longer ![]() Purpose= more air and fuel space = more power = more HP/Tq Overall the purpose it to make the motor have more power, this can also be accomplished with forced air induction systems. Blowers, turbos, superchargers, etc.

That was more understandable than I thought it would be. Thank you for explaining. So for those who want to keep the the car naturally aspirated but gain a good amount of hp this is an option?
