RE: Rev and speed limiter?
If you have stock valve train then 5200rpms is the max rpms. Your springs are not strong enough to close the valves in time before the pistons get there. Beyond those rpms you risk floating a valve into a piston.

Why would you want to push your motor farther than that though? The 318 isn't a high RPM motor. The tach changes color there for a reason
I don't have the Viper rockers in my truck. I'm not sure if they even work on the V10. The people that have done the swap have noticed a slight improvement though. If I remember, it's around a $40 or $50 swap.
If you want a mopar computer, find my Mopar PCM ebay thread and see if there's one that will work with your truck.

They might actually work. I've just never heard of anyone trying them on a V10, while I've heard of several people using them on magnum V8s. Most of the people I know of that have done rocker swaps on V10s have used the 1.7 crower rockers.
If I wasn't going for a cam, I'd probably look into it. But knowing I'll be doing a cam, I probably won't even bother with rockers. Just new lifters. Unless I get in there and find some wear on my stockers [8D]

Viper rockers are 1.7:1 stamped rockers. They'd be a steal at $70ish if they were rollers 
They're a good bump up though from the stock 1.6s though. The rockers I'm thinking of are from the mid 90s Vipers though. They might have switched to rollers at the end of the 90s, before going to the 8.3L V10.

thats true.. wouldnt hurt to ask at the local dealer parts counter.. could be a sick mod for you to do and ya never know.. you might like the rr's and put the cam on the back burner
