Thread: Just bought series 3 SC motor.

I have thought of it very much so. Buy apparently the motor was going to need a rebuild. But me and my dad think it just needs all new valve cover gaskets. It was obviously having oil leak out from there. And another issue is my car is a 03 so I can't put that motor with my tranny I'll need a 04 and up

if the bottom end was not rapping id use that over a n/a block any day.

So wait. Say that again? Cuz I heard only 03 motor will bolt up to a 03 tranny. Same with 97

the engine blocks and trannys are all the same 97- 08. the only real difference is the gears. gtp and n/a gp's have different gears in the trannys.

if you had a non hd tranny (n/a) and change to a HD tranny, you need the pcm tuned for the gear change.

or just put the new engine on your cars n/a tranny. just dont beat on it to much or it wont last so long.

Ah okay okay I heard something like the valve body's in the tranny or something like that is different. So if you were me honestly what would you do with this motor?
