Well I finally bagged a new set of Mamo ported AFR's to go with my Mamo ported FAST and 90mm TB. I also have new 36lb injectors, an 85mm MAF, ported LS6 pump, ect.

I am in the process of getting the last little things together so I can install this stuff. I think I have everything except for head gaskets, head bolts and lifters.

I was wondering if anyone has used LS7 lifters or if there was something better out there. My cam is smaller and has a lower lift (228/228 .571/.571). Any suggestions or preferences on lifters or does it not matter too much on an application like this?

 

LS7 lifters are the new 'stock replacement' lifters for the LTx and LSx engines, if you go to GM. They are a pretty good lifter, I don't know of anything better. Never heard anything bad about them. Though if yours are in good shape, you probably won't gain anything by changing to the LS7 stuff.

 

They are supposed to be good to over 7000 rpm. I'm using them in my new build.

 

Hey Adam, I am not really looking to gain anything other than dependability. My motor has 30K miles on it so I figure while its open I might as well change the lifters. Heads have to be off to change lifters so its a no brainer to do while its apart. The added insurance is worth it to me.

 

I re-used the stockers with no problems but I see lots of guys running the Cadillac Racing lifters whatever those are ( same as LS7? ) I have no idea but they are popular and cheap. If i swap cams again I will replace the lifters just for safety sake. No complaints here though

 

Yeah, I bought a set of the Caddy CTS-V racing lifters, before I ended up buying the VVT engine. Now I'm thinking that they probably won't be compatible, so I should decide what I'm going to do with 'em...

 

Well if you decide in the next couple of weeks let me know. I will be in the market for a set either from SDPC or private sale.

It looks like I will have a 228 cam for sale. Mine has lazy lobes which are great for stockish heads with PAC springs or 918's ext but for my application I will benefit from a quicker ramp rate and a higher LSA.

I was currently running a CC 228/228 at 571/571 on a 112+2 lsa but by goingto a more aggresive ramp rate and a higher lsa I will build more HP and TQ as well have more PTV clearance on the 114 lsa.

Should be a fun spring
