Would it be a good idea to switch my hyd roller lifters to a solid roller lifter for better performance? I know I can set the lash tight since the cam was designed for no lash, and I'll lose the lift that the lash occupies. But will I lose any duration? If so, how much? Right now I'm 242/244 @0.050. Thanks

Very little. I will be running Comp Cams solid rollers on a hydro roller Xtreme Energy cam. But only because that is how my combo fell together. AS far as more power- I think the extra rpm the solids will give would be the only benefit- and that may go past the effective power range of the cam. They are quite a bit lighter than hydros so will be easier on the valve train. Comp told me to set my lash to .008" cold.

BTW- how high are your shift points? I will be running a 347 w/ just a little bit less cam.

I haven't been to the strip yet to verify the fastest times with the proper rpm shift points, but seat of the pants feels like about 6900 or so. Its really hard to tell the 4.86 gears cuz it gets there real fast. But I'd say anywhere in the 6800-7100 rpm range.
