2016 Sema Mopar Hemi Swap
The crate engine says that it comes with a manual clutch . Will my 833 4 spd bolt to it and work ?
Your talking the different cam shaft grinds, are you referring to the new wire harness/computer being only able to work with the crate engine cam shaft or they all work you just don't get the same power ,truck engine vs challenger engine vs crate engine
The only reason it has a clutch, is because thats where chrysler plucks it off the assembly line before it would go into a stick shift challenger. I highly doubt it's of much use to you, as it will be for a new challenger. The smallblock bell housing pattern is the same yes, but the fore/aft spacing i'm guessing is not, as well as what spline count it has (tremec)
as for the cam question. What needs to be realized is this engine is one of like 6, 5.7's still in production. you have car, truck, MSD, and non. whatever a 2016 challenger with a stick has, is probably identical to the 345 crate. SO... if you had a different engine, say a truck, it's not that it won't make a "little less power" its that it is straight up NOT COMPATIBLE due to several things. MDS, Cam profile, ETC.
Have you ever heard of someone with an EFI engine "blowing it up" after a cam swap, and not having the ECM re-tuned? i have...numerous times. Factory ECM's are not Fitechs...or Holley snipers...the do not "Learn" anything beyond basic fuel maps.
Now on say an LS swap, You can have someone with livewire or HP tuners re-tune the factory ECM (or the ECM in the swap kits) to work with a different cam profile. (say a cam swap LS3)
BUT on a chrysler... if you have the wrong cam, or swap cams...i'm guessing it's not so simple. These ECM's in the mopar kits are probably 2015+ chrysler ECM's. If you go buy a 2015+ challenger...the factory ECM is locked to the point where you cant even buy a diablo tuners without also having to buy a near thousand dollar "unlocked" ECM... so being these mopar kits are based on production pieces parts... it remains to be seen if a PROFESSIONAL tuner can re-tune them or not. (without needing to swap out the entire ECM w an unlocked unit)
this is why Pace Performance developed our crate hemi's that are swap friendly 2 years ago.
the mopar kits are very cool, and the price point on the 5.7 is great. I sell them both so i'll gladly support either the mopar kits, or my pace hemi kits. BUT the point just needs 100% realized that these mopar controller kits being purchased W/O the intended configuration engine.
MAY end up being a monumental waste of resources and funds to make it "right" and may result in serious damage if you try to run it as is.
If you have a takeout 5.7, you're better off with something self learn, but then you face the VVT issues. I heard a horror story last monday of a guy with a "bargain" takeout hemi in a CJ jeep project. He has gone rounds with a VERY "Reputable" hemi tuning/wiring company that many swear buy...and it still doesn't run well over a year of sending a factory ECM back and forth... Just know what hurdles you're getting into. He is WELL over the cost of just buying a complete package at this point.
thousands into tuning/making that Used engine work...is very very close to what you would have had in just buying the new crate engine, and MATCHED controller kit. thats the entire point to my post.
