so MMX came out with a NTR NSR camshaft that claims +30 hp to 5.7 engines for $619. Too good to be true or to good to pass up? Thoughts?
But if you don't have to pay for a tune (and unlocked PCM) and pull the heads or sweat trying to change springs while they are in the car, not a bad return. And IIRC, they say a tune will add even more hp.hmmmm for all the labor involved in installing a cam in these new engines, might as well go with a good cam and get more than 30 h.p.
MDS only? Can't spot a non-MDS cam that is similar in their list, wonder why.Wondering what the specs are on that cam?
I think MMX is a CT vendor so you could try sending them a PM for more details.
if the owner is paying a shop for the labor - this isn't all the great of a return.But if you don't have to pay for a tune (and unlocked PCM) and pull the heads or sweat trying to change springs while they are in the car, not a bad return. And IIRC, they say a tune will add even more hp.
Really only need to pull the rockers/pushrods, radiator, water pump/timing cover and then slide the old cam out and new one in. Actually easier than an old engine since the lifters don't have to be removed unless you want to, then it is far more work than and old engine.
Is the work that is still required worth it for 30 hp? Don't know. Seems like people go to more work and spend more money for similar increases.
For me, if I was going to do (will probably do) a cam swap, I would rather go the next step and add the springs and tune with a bigger cam. Might even be worth it to me to actually pull the heads and put new lifters in just for the piece of mind.
But I would be lying if I said it wasn't a tempting prospect...
