i was reading some of the details of this cam on jegs websit it says

"We do not recommend the use of stock valve train components with these camshafts due to the aggressive lobe designs."

I was told that this was the largest cam i could go with on stock equipment. now that i read about little more about it, i read this now i am wondering. is it ok to use my stock springs and rockers or do i need to replace them as well? any help is greatful.

Stock springs and rockers are pretty weak. They're only barely adequate for stock cams, if your standards for "adequate" are real low.

NO aftermarket cam, not even an Edlebrock "performer", will reach its full potential with stock valve train hardware. Will it "work"? Maybe. At least for a little while. If the stock hardware is new. Will it "perform as advertised"? Absolutely not.

The XE cams are highly aggressive, fast-ramp designs. They are intended to snap the valve often as far as possible as quickly as possible, hold it open as long as possible, and drop it back on the seat as rapidly as possible. Stock springs probly won't surviv a trip around the block, with the beating those cams dish out. Even the little ones like the XE262.

Get the right valve springs and retainers and stuff for sure; and consider a rocker upgrade. The Comp 14 series are entirely adequate, and fit under stock valve covers, and therefore don't start the "chain reaction" of this doesn't fit, so I buy that; that doesn't fit, so I have to replace the other; now the such-and-such doesn't work because the other is in the way and it can't reach; etc. etc. etc.

 

do you have any #'s or a price on those rockers. i tryed looking for them but i couldn't find them. or i found them but didn't know it.

 

They're about $150 for the non-self aligning and about $190 for the self aligning version.

thanks for the link. well it looks like no new cam for me. don't have the income for both new rockers and the complete cam kit. is there another cam i can go with and still use stock equipment temporaley? i know it wouldn't be a good idea to use stock stuff but untill i get the cash to get the rest of the stuff to help with the rest.

 

Why not just save up for a few more weeks?

The deal is, the purpose of changing out the cam, is to get more valve action. In order to make the engine run stronger and at higher RPMs, the valves open sooner and faster and farther, and then close faster. Everything in the valve train is stressed more as a result. A cam that doesn't stress the valve train more, won't make the motor run any different from stock.

It would be alot smarter to wait for a while, put your pennies together, and do it all at once. Otherwise, you risk breaking parts, if you change the cause of the stress, and not the victim of it.

If you just have to spend the money NOW, get the springs and rockers and stuff; and get the cam later.

 

yeah now that i think about it a little more i think i will hold off on it. anyway i'm starting a new job so this project will have to put on hold for a while. thanks for the advice and help

 

I don't see why he can't use stock rockers, lots of people do. Just buy the cam, put it in and keep the stock rockers. When you save up, replace them. Just don't go crazy wtih 6000 rpm revs and you'll be fine.

 

i don't go over 5 anyway. i was going to do all this when i had the engine out of the car. just to make it eaiser on myself. but i don't know any more. starting pulling some body panels off the 83 and found somethings that i didn't like. looks like the it has been in one front end wreck. the support for the bumper cover was bent in and a new cover was put on. under thepassenger fender the floor pan is ****** up. the just put a new fender on it and called it good. so i don't know what i am going to do.

 

If you are able to save up the money, I would recommend that you get a XE262 K-Kit - that will have just about everything you need in it. When I installed my xe262 last year I also got new pushrods and 1.52 Magnum rockers (saved some money by getting them new on eBay). FYI, on the card that comes with the cam, COMP says they will not warranty the cam unless all new recomended valvetrain components are used.

 

I always found it cheaper to buy parts seperately from the kit....I spent about $500 including a new timing chain and electric waterpump, springs and the cam. Thats about how much a kit costs. Do the swap, keep the stock rockers, at 5,000 rpm, their not gonna hurt you but save up for some better ones. If I were you, i'd also run a stronger timing chain, double roller. Their not that expensive.

 

I paid 309 for the kit from Summit...the flat tappet kits are MUCH cheaper than a roller kit.

Ohhh, this is a flat tappet cam?

 

yes it is. i am not going with the cam at this time. i need to buy other parts for the car instead of a cam.
