every-damn-thread you make phoenix. you somehow get people to argue amongst themselves. and i mean that from an impressed view point. if you dont work in HUMIT you should. youd make a killing.

Reading the responses I am pretty shocked myself. I start out with a rather dumb and simple question and it blows up into this. Should I apologize? At least SS RRR got me thinking about this real hard. What I want to do have done on my car will be a far cry from what the vast majority of members have done to their cars and I understand where strong convictions for build advice tend to come in. I drive my car in the winter and I spend a good amount of time driving in the city so I need to have a very clear idea of where I want to go with the engine modifications. For now, it is nothing impressive, just trying to give a little bump here and there to the current output of the engine using small modifications I have read about and even putting on that intake manifold. I don't need much power given the driving conditions I face and my uses of the car.

I'm all for talking theory and physics. It's what I do everyday. There's a limit of practicality though.

I appreciate all of your input. In the end it seems that the best thing I can do, given my goals and the use of the engine that keeping the crank assembly stock is the wise choice. I can only "improve" upon an over 20-year old engine design so much given the restrictions and goals I wish to achieve. Thank you for this conversation.

If I need more traction I have slim tire chains but have yet a need to use them. Besides, in dedicated snow tires I often got stuck in deep snow since those pizza cutters dug holes. The wider tires seem to act like snow shoes, riding over the snow given their width, if that makes sense. I may struggle to get going from a dead stop but once moving it is clear sailing.

Sounds to me that keeping your car stock is what you need lol. You wouldn't waste a few thousand dollars on a lightweight rotating assembly for a car that you basically want to drive like a stock engine combination does. Other than a "very mild" cam and better intake/ exhaust you're going to effect drivability.

Steel 16" wheels fitted with snow tires. Function over form.

If there are any "improvements" that can be done to the engine then I might as well pay for them during this period. The lightweight crank assembly seemed like an interesting modification but unfortunately there is a trade off I am not willing to risk. I won't cry about it, so I am left with the roller rockers, the intake manifold, and possibly a custom cam similar in spec to my stock cam to work with this set-up, and I might as well see if they can throw on a Malibu Belt Alternator Starter system to help make the 5.7L LT1 a tad more fuel efficient for city driving and help to bring it into the 21st century. However, now I am off topic but this gives you, and the other members, and any other readers the grand vision for this build. Something still relatively stock and totally dedicated for street driving with the ability to perform for autocross if I so wish.
