Hello, I just bought a complete 2016 5.7 Hemi from a truck with the plan to put it in my 68 Dart. The engine has 11,000 miles.
The plan is the CASCAR intake with fuel rails, 4150 throttle body, Holley HP and harness. TTI headers.
I hate to tear it apart with only 11,000 miles, but I think a camshaft upgrade is in order.
Would you? Stick a 6.4 cam in it without making any other internal changes. Is that possible? Or, along with the 6.4 cam delete the MDS, change the MDS lifters, and new springs. Or use one of the Comp VVT cams, like the 270 or 274 with MDS delete, phaser lockout, new springs.
The Dart has a built 904 with a 3500 converter and 3.73 gears. My end goal is a DragPack style engine for a street strip car. Thanks!

The Holley system doesn't have a function to control the VVT , you'll need to lock it, you don't need to buy the $90 lock, you can open up the phaser and place a nut or bolt in the vain's(veins) 6.4 is a great cam, in your situation I wouldn't be so quick to toss the stock truck cam, it's .517/495 lift, in lighter application it's blast, but if your in there to lock the VVT like Dave said the MDS cam is about $70 and it's the best bang for the buck you can buy. keep in mind that the VVT system in these engines starts out fully advanced and than as RPMs and Torque management call for adjustments oil pressure retards the cam.

Thanks! I guess I just assumed they all had MDS. But thats not the case? The manual trans cars didn't get mds... also remember you must use the correct lifters with the cam. The mds cam is a lot cheaper and my engine had mds, so that's why I went with the mds style. There was a post here before that the non mds cam makes a little more power. I personally run megasquirt, ms3 gold boxes in my builds. They can control the vvt also.

a few dyno test I've done, has showed that the Non MDS cam made the same Peak HP and TQ #s as the MDS cam, but the Non MDS cam had a better average HP and TQ by almost 15Hp and 20ft tq, from about 2500-4000 but only you can decide if that's worth the $1??.00 price difference in cam and not to mention the price between the lifter types. I've seen the cam drift back or retard it's self under high rpm and oil pressure when the VVT is unplugged and the solenoid is left in, not sure what caused it just haven't had the time to figure it out. best bet just plug it if your not going to use it. http://www.stankemotorsports.com/services/index.htm

it starts out at 0 degrees and it can retarded the timing/cam up to 24 crank degrees.
"Could you use MDS lifters on a non MDS cam if the MDS is not activated?"
I don't see why not, but I would be cautious of the lifters bleeding down slightly in High RPM situation....honestly I never tried to use the MDS lifters on a NON mds cam, 1st thing I do with any MDS hemi is toss the lifters and buy new.
it's been my experience that locking the VVT is the best route if your not going to use it....it can be a great tool if set up properly think of it as built in traction control... my 428 in the 2014 1500 , would just fry the tires with the SRT392 cam, went back in to the engine, removed the lock out, my niece played with the VVT tables, and we got the truck to launch nicely by moving the cam back earlier in the rpm band.
Different story with the Comp cam, couldn't retarted the cam enough to keep the tires from roasting....had to go back to the right foot modulation system.
Now I've been playing around with the idea of advancing the cam by one tooth and then limiting the phaser to say 14 degrees ., haven't pulled the trigger on the idea yet, this weekend I'm going to see how it "looks" on a mock up 5.7 Dave any thought on it ?
