how hard to change cam? Well i had a dealer quote me job on cam. $2200 total says the engine has to be dropped. I imagine because the front structure is in the way, BUT, my structure is gone because i am repairing the frontal collision damage. Should i do a cam now and which one? I would love a deeper gear to take advantage of the bigger cam but i was thinking somethihng like the X5 giggliotti cam, or a similar grind. Is there a similar grind? Would this be the time to change cam? I was going to tackle it myself since i have change cams in 5 other f-bodies so this should be very similar.
$2200? Are you getting a high lift cam that requires springs and such? Is he going to dyno tune as well? That is way too much. If you have done it on your f-body you can do it on the gto.
A cam takes about 8 hours. Engine does not need to be lifted. Radiator needs to come out, AC needs to be lifted out of the way (not disconnected) and then pull the cam out the front of the engine. I have done 4 cams now in my garage. Each has its own unique frustrations, but a lot easier than headers! Takes longer, but easier.

As said above, the service manual states to pull the engine. This is not necessary. Pull the Rad (carefull of the bottom tabs, they break easy) and carefully flip the condenser 90 degrees. You will have all the room that you need.
Tips: Tighten the two oil pan bolts first when putting the front cover back on. You can crack the oil pan if you don't have the cover square.
I made my lifter holding rods out of 1/4 aluminium rod. Worked really well.
Buy the correct main pulley installation tool.
