Cam question
I have a 98 A4 with Lg long tubes, no cats, computer dyno tune, and a vararam. Would the Lg motorsports G5X3 cam make much more power without different heads on my car? Or any suggestions on a cam that would. Thanks Ken

With a tune I wouldn't be surprised by a gain of 40rwhp. I would expect at least 30 rwhp. But just remember, with stock heads you'll need new springs too.

I also still have the stock 2.73s out back, I would def change the gears and may as well do a stall while im in there if i did a cam. On a auto car would you go with 3.73s or 3.90s? I live 4 miles from work so gas mileage doesnt matter. Im thinking of goin with a 3200-3600 converter too. Gears?

Neither. If this is your daily driver I would go 3.42's which can be found relatively cheaply from a stick car that converted to a higher ratio. Remember you have the 2.73 gears now which means the 3-series gears won't go right in. You need a 3-series carrier and not a 2-series carrier. I believe DTE is currently swapping 3-series gears into 2-series housings but you're gonna buy the whole differential from them anyway unless you're local to them so why risk it? Go with a set of 3.42's and a stall converter and your car will feel 100 times more powerful and satisfy you 100 times more than just a cam swap.

The G5X3 is .600/.610 lift. You need the Comp 921 spring kit for sure as well as new pushrods. That's a lot of cam for your automatic tranny and gears - some would say maybe too much.
