ok, my uncle just got a 6.0 HD. he will be using it as a daily driver/ tow vehicle for the weekends. he doesnt want to put a cam in. but he said something about 1.8 or 1.85 rockers?
now my question is, stock 2003 6.0 with 1.8 rockers harland sharps?
what else would we need? would we need different push rods? and what is the equation you use to figure out what the int/exh will be after the 1.8 or 1.85's??
thanks for the help.

 

just say its .500 lift with 1.7 rockers take .500/1.7=.294(lobe lift) then take .294*1.85=.543 lift..but .500 is not the actual lift of teh 6.0 just using as an example

 

oh ok. thanks man. so do i just need the rockers??

 

yea..the pusrods should be ok..i know of people using stock rods on .550 lift cams..but they would be extra security..if ya got the money get them

 

ok, im going to put good push rods in. but i was thinking what size. 7.4 is stock, i guess i would keep the stock size PR'S right?? thanks for your help man. larry

 

Keep the stock rod length and get new valve springs!!

 

You should becareful with pushrod. I had 1.8 rocker arms with ls6cam.
my engine didnt' started.

 

What rocker did you use?

 

ok thanks guys

 

I have PRW rocker arms, with stage II heads from WCCH. I had tried to install them 5 times with 7.4 harden pushrods. didn't work.OMG.
I spoke to Richard at WCCH and he suggested me that I get little shorter.
(i'm going to get adjustable stud to measure it right.
Dont Use PRW rockers arm. they SUCK!
