The engine is a stock 346 shortblock and WCCH stage 2 5.3s. It is going to be a very mild setup. Not looking for a "max effort" engine, just something with a little more than normal, and an FLT 4L60e behind it. Probably going to put Efans and definately a full exhaust, too.

The cam will be a short duration (208/210 .560/580, somethnig in that range, because I want a very low power band, and high torque) if I go with GM lifters. My question is if I use the Rhoads lifters, will I be able to use a cam with a little bit more duration (214/216, with the same lift, approx.) and not sacrifice the bottom end torque?

Also, are those lifters any more a pain in the *** (higher fail rate, require more maintenance), becuase of how they operate?

 

For what you are saying there ... I'd stick with stock ones.

 

Here's a link to some lifters on SDPC's website: http://www.sdparts.com/product/12499...esSetof16.aspx

 

I know that the stockers will be just fine, but will I be able to get 5 or 10 more HP on the top, without sacrificing the bottom?

 

Here is a Tech page that I found, some good info. One thng is for sure, I ain't using them, I don't watn valvetrain noise on my DD.

ive heard of lots of problems from the COMP-R lifters

if you want to upgrade id say get some ls7 lifters

 

Comp "850" Lifters, they are a stock style replacement, none of the hassles that the "R" lifters have had. If you are intersted let me know, I have a set for sale.

 

Comp R's bad. Stock style Comps are ok. Melling makes some too, JB-2079. Theres also the Morels!!!!!!!!! But you wont like the price tag.

 

theres only one lifter for your needs and most of everyone's needs and they are the

LS7

ive ran them in my old motor and now in the 408

my old motor which now has a larger motor now has around 11k on those lifters and see 7k daily
