That being said, I'd still get them over the gt40's if possible.

you should see at least 55-60 rwhp with that set up alone.

Throw a little $$ into the GT40's, install that cam retarded a couple degrees and you have a very similar combo to my brothers that went 12.17 @ 111 with the 3.55s.

Just an FYI Justin.

I really want to install a cam - but in my past 2 expirences owning cars with cam's i've always had cold and sometimes hot idling issues. I suppose a tune would help that though...

definatly need a cam, if you had overheating issues before cam must have been installed wrong or you had some other problem. I have the Z cam, mine can litteraly run at idle all day without going over 220 degrees.

<p>corral has several excellent threads on which cams perform well with the gt40 setup, but you definitaly dont NEED a cam. 12 sec slips are common place with the stock HO cam.</p>

Besides springs, what do you recommend Brian? Also do you guys know of a reputable (and reasonable) place I can bring them to have some work done on them?

Not sure on a loacl place to you, ask around about the machine shops in the area?

As far as the work, definately springs, maybe look into a valve job and milling if possible. It starts to add up $$ wise, but makes the car run much better than just leaving it be.

My brothers car was fine with the stock cam, with his custom it has idling issues now. Won't idle cold, and then the idle surges and raises from time to time when warm.

There are plenty of cars with stock cams going 12s... (not sure how I would know that, ) and if you don't install it straight up, you can play with where the power band is some. A retarded stock cam will make power above 5500 RPM.
