VHP has a new trucker cam! Seen the new cam on their website the other day.

Specs 216/224/ lift 585. 585 lsa 115

vs.

The original trucker cam 216/224/551.551 lsa 115.

Looking for any thoughts on the higher 585 lift cam being a better cam on the 5.3 with mp112 radix. Thanks

 

That high lift version works out to be the same as using the .551 lift with 1.8 rockers. I can tell you first hand that it works very well with a Radix on a 5.3

 

That's kind of what I was thinking about the 1.8 rockers adding lift. I just did'nt know if the 1.8 rockers added with the high lift version would make more than the 585 lift.

And if that would make it to much lift. One day when I get the money for this cam I'm buying it along with some headers and tune thanks

 

very interested in this new high life vinci trucker cam.

 

The .585 lift cam with 1.8 rockers will give you just over .619 valve lift.

 

They must have changed there lobe design.

 

That's what i was thinking, so is .619 to much valve lift. Just asking cause I thought I read in some other thread that anything over .600 is to much, but I'm not sure about that.

Maybe the high lift version is used so you don't need to use the 1.8 rockers?

I may give Vinci a call and see what they recommend. If the higher lift will produce better results than that's what I'm going with.

 

I dont believe Vinci recommends using 1.8 rockers with there cams.

 

If you are still running stock heads, anything much over .588 lift won't make improvements, the heads themselves become the restriction. (In my opinion).

If you want to run the 1.8 roller rockers, use the .551 lift cam. If you want to run the stock rockers, use the high lift version.

 

Roger Vinci helped me decide how to set up my cam/valvetrain. I wanted roller rockers, so he recommended the 1.8 Crane Gold rockers with the cam in my sig. It's all about the combo, and everybodies combo is just a little different I guess.
