I have been considering a "cool" project .I would consider of swapping my stock Northstar engine for Vortec 6.2 .I wouldn't do it now because my car has a new engine with 20K miles on it .
I find my car quite fast but I wouldn't turn it down extra power .I am aware of Mark's 99STS but I don't think his engine will last long due to over mods on it .
In addition with a custom turbo or supercharger you would pay many $$$ but still your gain wouldn't get over 100 HP .
That's why if I can get a brand new Vortec 6.2 and it's transmission (I don't think 4T80E would handle with such a huge torque) and a new PCM to 6.2 ,I will have had 400 HP in my pocket and I think it would be much cheaper to Mark's 99STS .
What's making me worry is that my car is FWD but Vortec is only used in Escalade which is 4X4 .
Don't tell me to buy a Vette because I am not really into 2 doors and definitely love the way STS looks .'05 and up STS-V is not my choice as well.
Vortec is a real bullet proof engine because I haven't heard any bad stories on it and as a previous Escalade owner that engine is very powerful to handle such a huge truck .I had mine reprogrammed by the dealer and I gained approximately extra 30 HP,higher torque and better MPG afterwards.
