cc306: (230/244 .544/.576 112lsa) w/ 1.6RR's
Features Comp’s Magnum lobes with are older technology but proven not to take a beating on valve train components. Has been proven over the years to make good numbers and perform well at the track. Similar in power output with the newer XE 230/236 with slightly worse drivability. Exhibits a very strong mid-range and top-end with some low-end loss. Not recommended for cars that are daily drivers or that have stock bottom ends/heads due to its large size in duration. Stock heads don’t allow this cam to be used to its full potential so one with a built bottom end and head work would benefit greatly from this cam. Automatics require high-stall converters and gears and 6-speeds require steep gearing to run this cam successfully. Degree of cam surge will be determined by how good the tune is, stall size/gearing etc.
Pass Emissions?: No
Shift Point for Maximum Performance: 6400+rpm
Idle Characteristics: Very Choppy Idle
M6; Require Gears?: Yes
A4; Require Stall?: 2800+ Stall Speed

A cc503 is the biggest recommended cam for stock heads. It will drive well and make good power on the street and sounds good.



A hot cam is another good cam for the street and has good sound.



With any cam, you are going to need the supporting mods. At a minimum, I would do new valve springs matched to the cam and highly consider a good set of comp cam's roller rockers. How high you are going to rev the motor will dictate self aligning or non-self aligning. You can most likely reuse your lifters and you should measure for pushrod length. A cai and a free flowing exhaust will help. A new timing set would be a good idea. Any maintenance that can be addressed while the car is apart should be considered along with the obvious gaskets and fluids. And of course, you'll need a mail order tune. That is the BASICS! A higher stall torque converter like the ss line from yank would help with driveability and 3.73 gears would compliment that. A large trans cooler would be a good addition to the converter. If you want to get into the oil system, an arp oil pump drive is a good addition along with brazing the oil pump pickup to the pump itself (they tend to fall off) and a gm white spring in the oil pump for higher oil pressure to help increase bearing life.

Whoever said the cc306 was good for stock heads or on the street wasn't too keen on cam selection. That cam will want more rpm than the stock bottom end can usually handle. You will also NEED most of the supporting mods I mentioned along with others if you want the full potential.
