I have done some research and it seems that the LS7 lifters are good and the Morels are the best hyd roller on the market right now. I wondering if it is worth the price to buy the Morels. They are close to 5 bills, anybody know how much the LS7 lifters are running for a new full set?

 

Will the LS7 lifters work with a small base circle?
With the LS1 lifters, if the base circle gets too small the oil grove on the lifter gets too low in the lifter bore, and the lifter won't work.
I don't know if the LS7 lifter addresses this problem.
I do know that the Morel lifter was designed to work with the smaller base circles that come with the higher lift cams.

 

i run them and have logged over 3k in miles so far and seen 7500 rpms afew times and no issues

 

Are you running over .600" lift?

 

Quik's cam specs TSP Tv2 232/234 .595/.598 112

The new cam is going to be in the 620 range and 242/246ish on a 112. Anybody know a price on the LS7s. I shot out a couple of PMs so we will see what happens. If there isnt too big of a difference Ill get the Morels.

 

yea my lift is 598

my new setup will use LS7 lifters in my 408 with 615 lift and a 248 duration

as for price PM pewterssz. my price isnt what others pay so im not at liberty to say but they are nicely under 200 bucks

 

Just make sure the oil relief doesn't go below the bottom of the lifter bore with your smaller base circle.

 

HOw can I check to make sure the oiling hole on the lifter is still staying in the oil galley way?

He shot me a PM back and well there is like a 300 buck diff between the two so now Im really torn as to what to do. I damn sure dont want to have to pull the engine back apart cause if lifter issues.

 

whats the difference between an LS7 lifter and an LS2/LS6/LS1 lifter?

 

From teh pics I have seen over on tech it just seems to be a bit "beefier" thats all. Still looks basically like a regular lifter. They are also designed to withstand higher rpms then the older ones.
