Well anyways heres the story i have a 2000 cavalier with a 2.2 Ln2 in it. And its Pretty slow, so i bought a 97 Z24 motor. To make a long story short i was reading the sticky and theres a couple things i found out. ok so they make bigger cams that fit in the LD9. But in the sticky some one list something about W41 cams . The W41 cams are not a direct replacment. ive had to make spacer for the power steering pump. And make and barrel adapter to run them. Ive also had to cut into the carriers about .060 so they can rotate. So high output cams ok,w41 requires work. W41 cams part number (Mellings) MC1235 for the intake And MC1236 for the exhuast. Did i skip over a part in the sticky that said something about that? or am i retarded or something? And if im wrong with my specs, and when the cast carrier expands and smacks my cam does any one have a spare 410 cam?
Yes we already knew that LOL
If your going to run those cams your talking about... most people just steal the cam carriers alone with the cams out of the donor car and use them instead of the stock ones.. (or orders all the parts new)
Most cars with W41 cams dont have power steering.... although some people machine the one cam and make it work.
I cant remember if theres any piston clearance issues or not... I've never gone this extreme with a 2.4 (just "secret cams")
Also.... dude.... it sounds like your running W41 cams with LD9 springs and lifters (tappets)..... Im pretty sure thats not a good idea....
first off... i highly doubt there is anything in the sticky stating w41 cams are a direct drop in.... another thing, i wasnt aware w41 cams were available in the aftermarket. i thought gm only was the source for them, so i also doubt those part numbers were even intended for that use. i can almost guarantee they are the high output .410/.212 cams.
let me get this straight... you MADE the power steering hex? man... lol, you can buy it directly from gm...
so your running that high of lift with the stock valve springs?? your brave...

I really havent looked into valves or springs yet, im not to worryed clearence i droping my compression to 8:1. Hopefully the springs wont be a problem were only talking about a .050 difference. And to the picture of the nut. My 2.4 has a direct drive pump on it. the cams i have are set up for the old school pulley system. so my stock cam is keyed and my 410 is threaded. Does any have a differnet suggustion for valve and springs beside running vin a parts??
There are a few people running HO cams on the stock 2.4 springs around here. So far they are all doing ok but i dont think any of them have been together for long enough to truley tell how things will work out or if they will give up.
So your telling me people are running 410s on stock components? ill definitly look all little farther into it like madjack said becuz i dont want to have a huge paper weight on my hands. ill have to see if the old school 2.3a head is going to be a pain to use on my block. ill have to figure out chamber sizes, make sure the jackets match up and what not
I have done that swap actually. the 2.3 head needs to be matched up to the 2.4 gasket. There is a huge thread with pics floating around this site somewhere. Your compression will be 11.37-1 roughly, you will need 2.3 intake and exhaust manifolds, and the lifters from the 2.4 wont fit over the wider 2.3 springs. IMO not the best setup for a daily driver since you need to run premium fuel and should adjust timing due to the high compression.
I have seen on ebay a heavy duty 2.4 spring set for 100 bucks. It is from the guy who runs mantaparts so be aware, but from what ihear he doesnt screw up ebay stuff as bad as he did with his company, like not sending out orders and such. These should suite your needs well though.
ill have to look into that.i usealy try to stay away from ebay. ill have to look in a mellings book to see what the different specs are. im really trying to keep my compression low. i havent decide whether i want to run a hx35 or not yet. any other suggestions?
Stock springs with HO cams here for 6k, no problems. I am running all 35mm lifters, HO exhaust tower, and a modified intake tower. Stock springs can be used, only to 7k. After that you will drop a valve!

x2 on this, i did it for awhile stock springs and revving 7k on W41 cams
So is there a solution too running the w41's? like short lifters and longer springs w/ longer valves?
wow you boys are brave running ld9 springs with ho cams.
