ok for those of you paying attention to my intake posts ive had a perstistance of oil leaks.. originally thought to be the intake turned out to be the oil sending unit and now the intake really is leaking and sucking oil in after being replaced *sigh* so now this time they pull the intake im thinking.. hey why not put a cam in while its off!? dunno WHY i didnt think of it the first time... but now it sounds great... only thing is, the car has 147xxx miles, and ive heard everything from dont do it, to it might actually help it cause ur cam could be warn... so whats the real world situation here? (im looking at doing a comp cam not sure of the stats but im gonna get the same one my dad had in his before pretty mild with a good idle)
anywya what is a good suggestion for this cam or leave it alone.. if cam suggest what kind! (daily driver so i want a good "lopish idle" thats still pretty smooth)

 

Since this is a daily driver and you want a Comps Cam I would suggest a CC305 with the appropriate valvetrain components. At the very least you will have to upgrade your valve springs.

 

Just throw a 306 in there. I would cam in it but make a good choice on what you want and remeber that taking off the intake is only half the battle.

 

ok so what to? the LT4 springs? and i dunno what the cam is.. my dad lost the box to it so i have to get it checked to find out, and im not really "set" on that cam.. i just want something with a little more giddyup thatll last awhile with as much of the stock stuff as i can use cause im having it rebuilt in april.. but i figure.. well while the intake is off *shrug*

 

All depending on your budget put a cam in there. But you will need supporting mods. You'll need at the minimum hardened pushrods, matching springs, roller rockers, shims, locks, and probably new lifters and timing chain with those miles.

The best buy for the money would be a Hotcam kit. Rockers, cam, springs and little extra parts for 479.00 cant be beat. Althought upgrading the lifters and timing chain might cost a bit more I recommend going to an E-WP and getting a cloyes timing chain to save money and get some extra power. The lifters, I would get some kind of stock replacements, not Comp R's. Lifters and timing chain arent a must, but you dont want to be going back in there later to fix it.

If your budget is larger or you want more cam, talk to Bret Bauer and he'll hook you up.

Also the stock stall will be limiting your camshaft. The Hotcam/CC305 is the biggest I would go until you get the proper stall in there.

LT4 springs wont hold a CC305 with 1.6 rockers.

I started out with a cam swap on my 94 with 115k but i was nervous and chose to do full valvetrain. I guess that counts for nothing now though since I decided to rebuild(other reasons) and I am having lloyd do the heads and intake. I just felt better safe then sorry. I went with the cc503. Pretty close to the 305 but with a 112 lsa and I think it's just a tad bigger. Too tired to remember for sure though. On second thought that might be bigger than you want. I haven't had gotten mine together yet so i don't know. Wow I ramble when it gets late.

 

XE 224/230 Baby! It's the best of both worlds.

 

edelbrock extra energy cam? think it needs any support?.. just hate to have to tear into the valvetrain when its getting rebuilt in april/may ya know

 

It's the 503-8 Comp XE 224/230. It's torquey, lopey, and happy spinning in the mid 6's.

 

I wouldnt buy anything for a LT1 from Edelbrock. Personally it sounds like your budget oriented, just buy a Hotcam kit. If its not big enough, you can always change it out in the spring.

You don't want to be spinning a 147k mile LT1 to 6700 RPM in a daily driver. Stick with something in the 220/230 range (cc305, hotcam, etc.). Even then, you wouldn't want to spin that thing much higher than 6300 or so on a regular basis. You might look at the Crane 210/224 as well.

 

I know i was kind of kiding about the first part thats why i told him to choose his cam carefully.

And the 224/230 doesnt like to spin to he mid 6500s like chrism's does unless you have a rev kit like his. I know im gona get flamed but i would stay away from the xe cams they are to agressive but that is just my opinion.

How many miles do you drive the car weekly?

With gas prices lately i've been focused on small cam, forced induction that make awesome power or small cam, great torque convertor/gear/suspension packages that work at the track.

If you drive the car as a fun car I would say go for it, put anything you want in it.. But if you drive the car to work/school everyday you might think twice about dropping some MPG.

 

ohh alvin u posting reminded me of one of my other questions lol, so i need to re-tune the pcm before i start the car with a new cam or will it be alright to say crank it drive the 10-15 miles home and then let it sti till i send the pcm off and get it back??? oh and now i think ive decided on the cc305 (looked at the specs and im pretty sure its the one my dad has) plus im not gonna spin the car over 6k till i get it rebuilt, even when i send the computer im gonna have the limiter left there. and yeah i drive it everyday right now but thats not a have to, thats a choice anyway...supporting mods if any without spinning it over 6k... do i need?

 

Your going to need hardened pushrods, springs to support the lift, new seats and little upper end parts, and some Roller rockers. A tip, get some good springs and rockers so when you do the rebuild you arent buying parts twice.
