I have pretty much decided to do a 355 solid roller. I was wondering what valvetrain parts I would need to do this to a stock LT1? Would I need adj. rocker arms? Machine work to heads? Machine work to bottom end?

I want something that has some low end but pulls hard up top. I even had the idea of running 18* heads with a solid roller. Anyone have comments?

 

You're crazy, man!! Don't do it!!! Just playin'...bump for info.

 

joe,

all you need to change is your entire valvetrain. i don't think you have to do anywork to the bottom end or the heads.

obivously you need a solid roller cam, the proper lifters, i am almost positive that you're going to need hardend pushrods, rr's ( i would go with non-sa and guideplates) good springs. i would get a cloyes dr timing chain and electric wp. that's all i can think of for now!

later

 

Hey Joe tired of getting out ran by those LS1s.

 

youll also have to disable your knock sensors

 

I've been looking into doing this too, but looks to be too expensive for me though

From what I know you will basically need the whole valvetrain fixed up, like said above. Non self aligning rockers, 7/16 studs, hardened pushrods, guideplates, valvesprings, lifters, cam etc. Also you will need to pull the heads/get new heads to get them machined for the larger valvesprings that you will need for the SR cam. Maybe disable the knock sensor, some say disable, some say don't, I guess its up to you.

 

I wonder if the '93 (desensitized knock sensor) will need to be deleted?
