Yeah it needs to come off, I wouldn't do a cam swap without getting new pushrods, springs and 1.6's while you're in there, and I would get new lifters too.....you don't want the valvetrain to **** it's pants with the bigger cam.

car has a relatively new 383, tfs heads and all comp valvetrain, ported lt4 intake with big throttle body and in the next few days will be putting on the new msd opti, being the stock one went crapola. shortly, i'll be switching to a turbo set-up and don't need all the overlap from the cam i have now, that's the reason for the change while i'll be in the front of the engine anyway.. thanks for the info..sounds like fun for me
Have you read up on the MSD unit?? It is not the upgrade you are likely assuming it is. If the stock opti failed at low mileage buy a new vent harness, the stock opti is more reliable than the MSD. Guys will argue that one but some of them shut up after it fails at low mileage.
Reason the intake has to come off is to remove the oil pump drive.
Stock lifters are fine, I have never bought a lifter, put responsibly spec'd parts together right and you wont have any issues.
In my Caprice it is so easy to pull the motor that I just pull the engine and tranny together for a cam swap, I did it in car once and will pull the motor from now on. Then again I have never pulled the engine out of an f-body so maybe it is a nightmare. What I do know is the engine is a long ways from all sides of the Caprice and pulling it is easier than leaning way into the car for all that time. elps keep thing cleaner too, no accidentally dropping something into the oilpan as it dangles or anything.

Yeah, do take into consideration about the MSD opti. I'm running a MSD myself but only because it was my first mod I did when I did the tune up right after I got the car. Shortly after I bought the car I started scanning through this site and saw a few guys having bad luck with them. I haven't had any issues with mine but for the price of the MSD I would def go with the stock replacement if I had to do it over again.
