I think you would need dual springs for an ms4, not sure tho....

misho911

OK, what is the diffrent between the Single springs max lift 650" and Dual springs max lift 650"!!!!

I didnt know they made single springs to hold .650 lifts........so have u installed all of this or are u just asking?.....i dont see why 395-405hp and 370-380TQ isnt possible.

not necessarily, and probably not. , and the duration is a decent bit lower than the ms4. much more streetable and overall cam than the ms4, especially for the street and mild strip.

If im gonna max out my springs then i dont want to not be maximizing my power....its just my opinion but if this TRAK cam is the same lift as the MS4 i would rather have the big dog, atleast that way when im changing springs every 10k i know it was worth it and dont have to think that i coulda gone bigger.

dont change it to a ms4...if anything go with a custom grind, but ms4 is a cammotion cam not a comp cam...so keep that in mind when maknig your decision. and i would talk to predator z or patrick g first and let them spec out a cam that will put up better numbers than a off the shelf cam.

misho911

please could you write thye link for the predator z and patrick g

MS4 is a Comp cam grind LSK/XE-R

The TRAK is more proprietary to Thunder and is an awsome cam. Properly done the TRAK will be within 10 rwhp of the MS4 assuming all is optimal.

I would not change TRak for MS4 if allready installed, I would put on a nice set of heads instead, if on budget like stage 2 Livernois 243 casting

Thanks PREDATOR-Z for your advice,
But from where can i buy this heads????
and what you expect the max rwhp and rwtq? if i install this heads?

Predicting horsepower is like predicting the weather. Properly done it will make a lot, more with a bit of nitrous

misho911

Thanks
i will check the heads....

My 01 Z06 made 465rwhp 422rwtq and reved to 7300rpm on stock internals with some $2800 (at the time) ET 2.055 LS6 heads. Had dual springs and had one break at around 7200rpm... inner spring still held and kept my valve from falling into my engine, and ruining my expensive heads It's nice for added safety.
