looking for a cam.....Whats the opinions on max lift you can use stock L92/LS3 rockers on without problems or durability issues?

 

I would not go over .650 . It becomes a swipe issue over the valve tip. I am currently building ls7 with stock rockers and lift of .661 and the movement front to back on the stem is about as much as I would want...I would go with aftermarket rollers if I was going with any more lift on my build.

 

+1 on the .650 the geometry gets off. More than that buy some Harland sharps or yella terras.

 

I'm looking at the TSP 229 & 231 cam, .624 & .641 lift respectively. I know others are running the 231 with stock rockers and the PRC EHT springs...anyone have thousands of miles on theirs? Any problems?

 

5k miles here no problems

 

I am running .665 lift on the intake. rocker pedistals are shimmed for proper swipe. motor has 8k miles, and 12x track passes. ZERO issues for me.

 

.621" here with Comp Trunion Upgrade, no issues.

 

hmmm, did your sig change...i've followed your build and based mine off alot of your info...
Didn't buy the cam yet. You stated, if you had to do it over again, you wouldn't have milled those heads and got a bigger cam...larger duration?

 

Nope sig hasnt changed in years. I have awesome heads, a little more cam would help. PTV/ Pistons are my limiting factor.

 

I'm running .644" lift on the intake, with stock L92 rockers and PRC EHT springs with no issues. 5k on the build now.
