What i have. 84 Z28 with the LG4. Stock 3.23s Weiand Intake Hooker shortie headers. What i plan to get before or soon after the cam swap L69 Computer build the rear with 3.73 posi. Port and polish the heads My use. i plan to build a new engine (355) but i want something fun to play with while i have the 305, heck if i get another car with a v6 just swap that in. with the 305 i'll be driving as close to a DD as possible. i'll probably be getting on it quite often. ok so i was looking at a bunch of cams and heres one i'm particularly interested in/wondering if it would be alright. in addition if theres anything that i would need to do. http://www.compcams.com/Cam_Specs/Ca...x?csid=78&sb=2 any thoughts? suggestions? criticism? bad jokes?

It should be a fun cam. Not too radical and not too tame. It depends on how many miles you're going to put on it as a daily driver since the gas mileage will be traded for power.
You'll need lifters and springs and maybe rockers (depending on the heads).
I wouldn't spend a lot of time porting the heads as these have the 1.84" intake valves and it's not going to make much difference. Get the heads milled instead ($20ea) to bump the C/R from 8.6 found in the '84 to the 9.5 found in the '85 LG4. The cam swap will lower the dynamic compression ratio more than enough.
Does it have to pass emissions testing?

well as for driving everyday if the legacy continues, it will run for about a month, something else will break, then it will sit for 1-2 months.

as for emission tests, ehh.

i got it inspected in august. all the smog stuff was gone and it still passed.
and i dont think the place i took it to did it just for the sake of passing.
