Ok guys- got a full exhaust, i could put headers on it, and i pretty much plan on getting either a performer or air gap intake... heads could be ported, if it would be worth the bucks.

basically, these haeds i am getting free, they were rebuilt about 5000 miles ago. so they have to be cleaned up, and could be ported for about 150 bucks i think. Worth it?

Plus, I REALY NEED IDEAS FOR A CAM... i have no clue what to get... i will be using the computer sooooo.

thanx guys- steve

somebody has to have some suggestions here guys!

A good entry-level performace cam from just about anyone would work better than the stock one. Something with about 260-270 intake duration, little more on the exhaust.

Don't go crazy with cam duration cause the motor doesn't have much compression (about 8.5:1) and a bigger cam will kill cylinder pressure making the thing a dog on the street.

79 Malibu "beater" w/junkyard 400 SBC, tweaked QJet 4bbl, finally a decent set of heads, a few other tricks. A maddening 13.000001 @ 108 on the motor with little traction. No nitrous runs with the new heads yet.
Grandma's old 78 Malibu (33K miles!) soon to have the powertrain from the 79 put in it.

Daemon- Didnt the 85 lg4's and earlier have the lower compression?

when i did the compresion test, and did some math i got 9:1 for the compression ratio.... Any how, thats a lot of duration... i was thinking something along the lines of a 420/440 lift and 218/224 duration... and a 110lsa.... sound like something decnet? just want to get the most bang for the buck here

nope your's is 8.5:1

Crane's Compucam 2040 looks like a good canidate. I wouldnt goo much bigger then that unless you have 3.73s or a high stall TC.

There can be only one!!

 

ok, well the compucam 2040 looks realy good- but what do you guys think- 2030 or 2040??

2030:
Degrees Durration @ .050 - 204/214
degrees advetised- 264/274
Lobe Seperation- 110
Lift- .423/.446

2040
Degrees Durration @ .050 - 210/216
degrees advetised- 270/276
Lobe Seperation- 114
Lift- .440/.454


Now the biggest difference as i see it is the lobe seperation... 110 vs 114. can anyone tell me what that will change or do?

i think i am leaning more towards the 2030, to keep some driveability, but crane also makes hi intesity lifters, that below 3000 rpm, reduce duration and lift... would that be a solution to this.. cuz i really wouldnt mind throwing the 2040 in.

My recommendation would be a Comp XE262H. Check the specs on their web page. Some other people on this board have used this cam in that motor and love it. You will definitely need headers for the cam to do its job: the TES is an excellent choice. If at all possible, DON'T get the one for the LG4, because it is designed to hook up to the stock exhaust pipe which is dinky. Basically you'll have a big exhaust next to the heads, and a big exhaust behind the cat, but a pinch-off at the cat because it will be 2½". Get the TES for a L98 instead, and a 3" cat of course.

You really should lose that grocery-cart gear... you wouldn't believe how much difference a set of decent gears makes. You'll probably get more resuts from that than you will from a 350 or a cam or almost anything else you can do under the hood.

well, i have an slp 3inch cat back with a 3 inch cat, hooked to the stock y pipe!! so anyways, i have the l98 headers...

yeah if i can get my hands on a used diff, i might consider putting in some used 323's that i got

Do you have to go through an emissions test? If so, the milder cam would be most likely to pass. Others have said you can get through with the performance-oriented cams, but you have to decide how much hassle you're willing to endure.

Also, if you have emissions testing, the Performer is the only one that will pass visual. The Air Gap would probably have problems passing at idle, even if it's only a sniff test.

yeah there is no visual here yet! basically, i am just makeing the car seem better than it is for when i sell it. the car smokes bad on start up, and to alleviate that, i have set of heads for it. can't beatthe price of them- free. so i got to thinking what kind of options i got etc while i got it torn down. cuz it has a BAD lifter tap in it. so anyways, just tryin to get ideas. i dont want to spend mucho money on it cause i plan on selling it in the spring to get a nicer car, like a 88-92 formula or trans am.. but either model i want the 350

There's no visual in CT? A guy on the v6 board said he couldn't replace his 2.8 with a 3.4, because of the visual. Hm. I'll pass that info on, thanks!

yeah there is NO visual in CT. they tried to open my hood when they did the safety inspection on my car and ran out there and told them if they opened my hood they were not going to have a job any more. its a SAFTEY inspection. they look for rust, a cat and test the brakes and make sure the lights work. THATS ALL.

As long as your car passes the sniffer test then you should have NO probs. you just dont tell em that you got a 3.4 to begin with. and you can get away with it for now cuz they dont test flow numbers...

Steve

 

well steve they probably wanted to open your hood to make sure you had a battery tie down, cause that's what they did to me.

yeah maybe

i told them no and they couldnt give me a reason to look....

I have the comp XE262H mentioned above and i love it. the only problem is my 3.08 gears, they kill me...one day ill toss them tho, im actually looking to build up a whole rear. anyway, my point is thats its a good cam...you'll **** your pants the first time you start that baby up, its nice...pulls hard as **** too.

i dunno... i think that 262 cam is a bit much for a 305....

Steve

 

I have a cam w/ nearly identical specs to the 2030 in my 305 TPI. Idles and drives fine but made a big difference over the peanut cam. Worked well w/ the stock chip and w/ the ADS chip (no real change at part throttle in that chip anyway).

For me, I kinda wish I had of gone w/ the 2040. The 2030 is too tame IMO for what I wanted. The 2040's specs look about like what I'd try if I had it to do over again. I do have 3.42 gears though...

You're doing this to get it ready to sell? Heads are one thing, which I can understand to stop the smoking at startup, but doing the cam is a lot more work than heads (although that's the right time to do it if you really want to change the cam). Throw in a set of lifters on the old cam while the intake's off to stop the tapping noise (no, it's not guarenteed to eat up the cam).

Do the heads, but save all the good stuff for your 350 car.

yah, i thinking that im jst goingto do the heads, and maybe the cam if this car i am looking anow doesntwork out. sounds like the 2030 cam would be the best bet, since i have no intent of changing the gears now. Hey chris still got that cam, chain and lifters???

nope i never miss 3rd, that was only cause the clutch was messed up, no i hit it everytime that was from 5500 RPM Dumps
