That cam may not work, since it is for the Chevy II. Don't buy anything until you actually call up the cam company and get their recommendation. That looks like a more suitable grind, though.
I searched for a Pontiac 151 on the Comp Cams website, and this was one of the reccomended cams. What kind of power gains should I be looking at with this and my mods? I really want to be able to keep up with a stock GT, atleast.

I've read thread after thread about building up the tech-4. If you want enough power to even break even with a stock GT (2.8, manual tranny) you're going to need much more than a cam replacement.
Do some searching for tech-4, duke, or 2.5 build-ups. You'll learn that the tech-4 was built for economy and has a very weak bottom end. It just wasn't built to make the kind of power you're after.
good luck Dave

Does anyone know the best way to install this cam kit on my "Tech 4," because I think I am going to purchase it tonight?
Remove the dogbone motor mount on top of the engine, disconnect battery cables to battery, disconnect fuel lines to intake, disconnect vacuum lines going to chassis. You're doing this because you will be lowering the passenger side of the engine out the bottom and don't want to rip anything off as it comes down. Any other hose/line/connection that looks like it might get ripped when you lower the engine on that side, disconnect them too. Remove valve cover and loosen rockers.
Raise the passenger side of the vehicle and put a jack-stand on the chassis just ahead of the cradle. Remove the tire. Remove the plasitc splash guard in the wheel well. Remove the pulley belts. Support that side of the cradle with a jack. Remove the two cradle bolts on the passenger side of the vehicle. Lower the jack holding the cradle up and it will come down quite a bit. This will expose the timing cover.
You are almost there. Remove the lower pulley bolt and pull off the harmonic balancer. You're looking at the timing cover now. Remove the bolts holding it on and there you are. The big gear on top needs to be removed with a puller. You'll have to tap some holes in it to get the puller mounted (see Ogre's cave for good info on this part, it's important to do it right, link is at top of the page). Cam can be removed. I would think you should rotate it a couple times before pulling it out to get all the lifters up and out of the way.

Funny you say that, my 85 fiero SE 2.5L's of fury kept up with my buddies 87 gt auto till 105 km ( 60ish mph) i was accually ahead of him till that point
and my other buddies 85 gt 4spd was only 1.something secs faster in the quarter then mine all ihave done it s slightly ported intake, holley muffler and a K&N filer oh and my timing bumped up to 10* advance... not sure if it made a difference but i dumped 500cc's of 10% nitromethane in my tank too ( rc fuel)
