It was pretty much determined by all the cam experts on this board that that is not the correct cam for the 402 due to where the valve events happen. I figured that I would just swap it out as it was the recommended mate for my new setup. Maybe someone else can give a more technical explanation.

and retard the cam and you move the torque band up.
If you have to move the cam more than 6-7 degrees, then you have the wrong cam.

You have had the heads almost a month already!!
(sorry to slightly hijack Carlos's thread!)
Looking foward to some results....hopefully it's a
when the smoke clears. Don't forget these heads might want a completely different fueling and spark table to maximize their performance.Rambo, I PM'ed you BTW.
Regards,
Tony

I have been following a few of your threads with your 402 builds and just curious if you have any new numbers or updates with the new cam and intake. I am basically in the same situation as you, just trying to figure out what cam I want to switch over to.

Latest update is that I did finally get my hands on the WBO2 but my buddy did not give me the serial cable with it that I need in order to setup the voltage correctly in order to log thru HPT and the EGR connector. I hope to have this tomorrow. I have been fighting the 98' KR bug also.
Prior to this delay, I had another delay where I snapped 2 of the studs in my rear right wheel. I had to wait for the new longer/harder wheel studs to arrive. Since I was going to be jacking the car up in the rear to get the new studs in, I ordered a new pan hard bar and some tubular lower control arms (fixed the clearance problems with my 15X10 wheels and my 325 50 15 rear tires).

what springs would i have to run in order to run this cam? or is this a solid roller set up?
im looking real hard at the dart 225 head milled .030 and .030 cometic gaskets on my LS2 403..... as of right now static compression is 10.8:1 if i were to reuse my stock LS6 heads unmilled. im repeating what i can remember from what the builder told me. diamond pistons -2cc with valve relief cuts that make the pistons -11cc i believe, id have to double check.

i think i am going to run it. i have seen you suggest this a number of times and suggested it to me in a previous thread a couple of months ago.
what about running less lift, what changes would be made to the duration if any?
the shop that built my short block, suggested running .608/.621 242/250 112+4, with their CNC LS6 heads
