I have a LQ4, was hoping it was a LQ9 but its not, I already have a trak cam, will I have any pvc issues with this cam if i mill the 317 heads to get the compression up? It has the dished pistons. What should I do?

 

I have a set of 317's and a set of L92's also, which should i go with, not sure if my cam will work with the L92's

 

I'd go L92 and get a custom cam ground.

 

Your concern is with ptv issues, not pcv. I don't know how well L92 heads flow. I know 317's are similar to 243 castings, but with larger combustion chambers. If you don't mill the heads a crazy amount, I don't think you will have any ptv clearance issues.

 

Thanks, I talked to Texas Speed and they said I can't mill them enough to run my cam, so I'm looking for Ls6 heads.

 

dont build you car around the cam, i would use the l92`s and sell your cam, notch the pistions and mill the heads some.

 

what cam for l92's

 

It's not that simple...
What are your power goals?
How is the car going to be used? Street/Track?

 

please go with the L92!!!! it flows over 300cfm out of the box! get a custom cam too like they say.
L92 love small cams; check with synergy motorsport in the dyno section.something in the 22x range ...
