Im thinking about gettin some roller rockers for my stock L98 heads. I would also like to go to a stiffer spring.

Im keeping the stock cam for now. Which rockers would work good, and which springs will work without any bind.

thanks for info.


Ps. Im thinking of going with trick flow heads later, and would like to use them on the trick flow heads. Keep in mind I will be converting to a stealth ram also, before the new heads.

 

GM Performance Parts 1.6:1 self aligning roller rockers that came in my LT4-HOT cam kit.

The kit came with springs which I'm running, don't know what machinework is needed to fit them onto stock iron L98 heads tho. They're good to 0.525" lift (exactly what the LT4-HOT cam does with 1.6:1 rockers).

 

I have the same setup as him.

 

I have Harland Sharp roller rockers in my l98 buildup on vortec heads.


These won't fit under the stock valve covers, I got TD Performance tall valve covers. I think Comp Cams make rockers that'll fit under the stock valve covers.

 

The GMPP rockers / Crane Golds (same thing) will fit under the stock valve covers.

 

ooo what purty engine (drools)

 

i am thinking of getting roller rockers next winter. My motor L98 was just fully rebuilt. How much of a power difference will I notice along with my setup (exhaust, intake, ported TPI, SLP 1 3/4 headers, MSD) ????? 10hp?

How hard to install?

 

Comp Cams Pro Magnum

 

Same as above.....

 

Crane 1.5 Roller Rockers

 

Comp Magnum here too. The self aligning type. They also fit the stock center bolt valve covers.

 

Thats what I got.
