LS1 and 5.3l

[mikystyle]

Whats the differences between the Ls1 motor and the 5.3L motor? Are some aftermarket parts compatible?

Same block design but from there it gets sketchy, the heads are similar, like manifolds and etc will swap but the LS1 manifold is a short runner design for high horsepower and the 5.3 is a long runner for torque, so yeah they are similar but not the same. You can swap cams and stuff. a popular 5.3 mod is a Z06 cam which slides right in without any modifications

Thanks, thats exactly the info i was lookin for. Can the Z06 cam just be put in or do any other mods besides reprogramming have to be done, like springs or something? How much gains could be expected from the Z06 cam? Thanks

any cam requires a Dyno tune to make it work correctly. I am currently looking into a lingenfelter cam swap myself.

It is a great cam for all around use without having to replace the Torque Converter

 

:edit:

 

The expected HP gain is somewhere between 30 and 35 with a proper tune
