Yes. I own a 2003 impala. And my stock engine is the 3.4L or 3400 sfi v6. The same likewise style impala from years 2000-05 come stock with either the 3.4L, 3.8L or even the 3.8L supercharged. So there is quite a bit of room under the hood of a 2003 impala
No.
Do a 02 grand am transmission fit in a 03 impala
Any smallblock Chevy engine will physically "fit" into a 85 Impala
Yes
will a 3.8l engine from a Pontiac grand prix fit in chevrolet impala
If you have the time and money and the know how you can pretty much put any engine in any vehicle with a torch and a welder.
no way.
one is a Chevy and one is a Chrysler, you do the math.......
Purolator L22500
1969 Chevrolet Impala 327 cubic inches
A small block 350 cc engine will not fit a 2005 Impala, but a 327 one will.
I don't see why they wouldn't. The police package (9C1) engine and tranny are just built heavier. The engine is beefed up a little more and so is the tranny. As far as I know they'll fit right in there.
