I am betting the heads will be mostly stock just the port and polish i was wondering whats the common off the shelf cams were that would work with the stock heads. He basically went in and asked what would it take to get that heavy lope at idle so i wonder if there just going to try and stick the biggest lift cam with the most separation they can find in there.
Again, either the Viper Coupe Cam (or the Mopar Cam, as mentioned above) make a nice choice. I went with a billet roller based on the Coupe cam but changed specs. here and there to work well with the Strikers. Mine has a lope at idle (I wouldn't call it heavy) but I am also running an auto and didn't want a cam that kicked the shit out of low-end torque.
The LIFTERS on these engines tame the cam a bit around idle so to get a big lope at idle, the cam will need to be even bigger than what would normally produce a big lope, with a more conventional lifter design.
Finding more conventional lifters for these engines is a real problem, as they don't seem to exist.
A big lopey cam without an increase in your static compression ratio by cutting the heads and/or the block, and/or a piston swap, WILL lower the operating (dynamic) compression and these engines respond well to MORE compression, not less.
A few guys on this Forum have changed cams in their trucks and maybe they will also give you some pros and cons....
THE CAM SHOULD MATCH THE FLOW CAPABILITIES OF THE HEADS. I mean, what is the point of a big idle if you lose usable power in the end???
Again, I don't know what has been done to this engine, what is going to be done, if you care about driveability or what your final goal is....
I went with a setup that gives me enough power to pound on the stock Viper cars at the track (well prior to the Gen IVs anyway
), and even gained some gas mileage! It sure isn't an all-out power build by any stretch, but it is
what I wanted.
Tell your engine builder what YOU want to have in the end and hopefully you will hit your target...
