I did an in car cam swap in my 87 IROC 350 2 months ago. You have to pull out the fans, radiator,AC condenser (if equipped), and those 2 metal braces in front of the radiator to have enough room to slide out the old cam and put the new one in. You don't have to remove any body panels, at least not on my car.

I did mine with the motor in, only to pull the motor later (DOH!). Front accesories need to be pulled to either side, water pump, fans and radiator need to be removed. A/C condensor and supports can be moved to the side.

if you don't have a manual you ought to buy one before you start the swap. i'm sure none of the manuals will say to remove the fender to change a cam.

I'm assuming you're talking about comp cams XE268H? That's a whole lot of cam for a 305 - also, your stock vavle springs are only rated to .47 which is really pushing it with .477/.480 lift. If you haven't bought it yet I'd go with the XE250H or XE256H.

i know it is pushing it, thats why i have replaced the springs, rocker arms, and pushrods.
from what i have read in many posts you see no benefits from changing the cam and not at least modifing the heads to accomodate them and the engine damage factor. thank you for your concern.

one more question what kind of special pullers do i need to remove the harmonic balancer and crankshaft? it says in the haynes book that i need special tools to remove and install the harmonic balancer.
whats the benefit of an aftermarket balancer?

you need a puller for the balancer, i believe they call them a flange type puller and you'll need an installation tool. if you change the crank gear you'll need a common jaw type puller also.

I agree with Dan. I removed exactly the same items on my 82-305 to put in a Comp Cams K-kit. In fact I am still putting my car back together.
You don't have to remove any body panels.
As for the harmonic balancer puller, they sell them identified as such at most auto parts stores or Sears.
You will need two Grade 8 bolts of the proper length and thread pitch to screw into the balancer. Be sure you protect the threads on the end of the crank, or you will have big problems later. A shop manual or a small block rebuild manual is almost a must unless you have a lot of experience.
