You don't need to replace ALL of the valves, you just need to replace the valve that made contact with the piston. That will save you some money, Glad to hear that you're going to atleast though, it really is needed =D

As far as lifters go, I have the morels as well, they are some really nice pieces, but you should be fine getting the GM high-rev lifters.

I never had any trouble with any of the lifters I used but it never stopped me from putting in better ones each time I swapped to a bigger cam. You could use the regular comp replacements if you wanted to not the comp r's. I've not used the R's but was steered away from them anyway. The regular comp replacements worked fine for me. 238/244 is not a mild cam btw.

I'm not telling you to spend more money, you asked for suggestions and that's what you got. To be perfectly honest I'm using the Morel HTL in my new engine, even more money than the regulars but I consider it to be a very important part so I'm looking at the options and making the choice to go with the best I can find for peice of mind.

my philosophy is use the best quality products the first time, so that nothing breaks, and then i have to replace it later with the better quality product and end up spending even more money....i am also going witht eh morel htl's on my medium camin my 408

This is why I dont totally agree... I used the beter quiality lifters at the time of my LS1 Tv3 (caddy lifters) and they failed...

238/244 isnt a mild cam for a 402??

So why is the LS7 not a good lifter for this cam?

I usually dont cheap out on products, in fact I get made fun of within my friends for usually spending a lot of money on a little bit of better quaility items... Why I am now trying to conserve some money is because this year I unexpectedly spent 5k+ on a new 402 and Im still in debt and now there is more and more things to spend on... Thats why...

I never said there was anything wrong with the ls7 lifter at all. You just asked for other options and so I gave what options I use.

With the heads your running being the limiting factor I would have gone with a smaller cam to better match the heads. I think you'd get better average power.

Patrick G speced me this cam for a good driveable car with these heads and some decent power... So its gonna be driveable and tame, but make decent power from what I was told....
and even if you are right, theyre grinding this cam as we speak

Thanks, is there any stories of the LS7 lifters failing? By far ive heard the caddy lifters failing the most... Ive heard at least 3 different stories

99blancoSS

Not that I've heard but I have heard of issues with the caddy's as well. I guess I misread and thought you had an issue with an ls7.

I know someone who was doing a cams swap and swapped out his ls7's on his c6 z06 to the caddys and the oil pressure was real low. He did a bunch of seaching and cleaning looking for any obstructions, found nothing but the Ls7's back and all was fine. Was most bizarre.

Guys, a 238/244 113LSA cam in a 402 is like a 228/234 114LSA cam in a 346. This is not a big cam. Also, with the small valves or these 5.3 heads, the 402 is going to need more overlap than a much larger head (like an L92). Just can't make the same comparison. A 402 with small heads will easily gobble up this cam. Wouldn't have been my cam choice for L92 heads, but it will rock with these 5.3 heads.

When W2W built the 402 that I am running, Billy suggested that the stock LS1 were fine for my application. I think that when it is freshened up, I will go with the Morel for piece of mind. If you do a search, there are pics that show you how much more beef the Morel's have. Good luck.

If you can tell me the LS7s can fail and the Morels will not fail at all and gimme an absolute guarantee. that is the words im looking for to buy the morels, till then, if the morells can fail just as wasily as the LS7s. then it isnt worth it... Im not going too high RPMs, the cam profile isnt that agressive and the lifts and ramp rates arent too crazy...just a pretty long duration over a stock LS1 or LS2 cam....

The morels GUARANTEED will hold up better then the GM lifters. I'm running Morel lifters, and they are a serious piece of equipment. Whether your application is extreme enough to call for the morels, I would probably say no. But if you want that absolute guarantee, then the morels are your best bet. Only thing with the Morels is once you get them installed, and the heads installed, you HAVE TO measure with a pushrod length checker to 0 preload, meaning the lifter is on the base circle of the cam, and you measure right up until the rocker arm, then add .02" to the length for your pushrod, for your cold preload, so you WILL NEED custom length pushrods for the intake/exhaust lobes (if they have different base circles).

Otherwise, the LS7 lifters will suffice, and thats what I would recommend, but like I said, for that absolute guarantee, the Morels are your BEST bet.

Can someone remind me the disadvantage to solid lifters?

iTrader: (115)

Having to adjust them and check them. You can screw them up real easy, experts do it all the time..LOL Mess them up and your down on power at the least, doing damage to expensive parts is possible as well.
