hey, would it be a bad idea to put 3.73s in my car considering that i have a near stock lo3? should i wait for a cam to get a longer power band?

no, it will make a noticeable difference...

yah, but wont i loose alot of top end power

You won't lose top end power, but your cruising RPMs will rise considerably. Also, your top speed might be a bit lower.

exactly what Bandit said. changing gears will have no effect on engine power, just the RPM range you use it in...

... but it will feel like its got quite a bit more power.

yeah, you said it Adam...
