Biggest difference between ramjet cam and the comp is lift. I'm at .460/.480 with 1.6:1 roller rockers on the ramjet cam. You'll be around .530 you said.

Yup. That combined with the better flow numbers at high lift from the AFR heads. Vortec heads wouldn't be able to make use of that high of lift, plus all the extra work I'd have to do just to make them survive it.Biggest difference between ramjet cam and the comp is lift.

You're going to need the marine intake to use with the Whipple without fab. The oh so difficult to find intake.
Oh, and I'm currently running the ramjet/marine cam with 1.6 rockers as well.
Usually I would agree. But I don't really have the time to space it all out, I do have the time to do it all at once. The unit I'm going to has an extremely high optempo. Constantly on training missions and deployed.As an interim measure, have you considered slapping the injectors in with just the Whipple? I personally don't mind retuning around crap like that.
What's the plan to deal with exhaust post header? Or are you going with bolt in shorties? You doing just the pump or pump and basket? Your 98 has the later plastic bucket design. If the Whipple kit is complete then it will bolt on quickly and easily. If not, I could see some snags. I put a 340LPH pump in my dually, didn't monkey with the wiring or anything and it's done just fine FYI. I got the cams out of both of my trucks without cracking the AC system open, but I did have to yank the grill and everything out to swing the AC forward enough to clear it all. What do you plan to do for pushrods? I see those heads use guide plates so are incompatible with a self aligning rocker. You're going to end up measuring for pushrods and you'll need hardened just as a heads up.
