90 Camaro 5.7 in 91 Trans Am 5.0?
I have a 1991 Pontiac Trans Am with a bad 305 (Piston rings) so I think its time to go for a 350.
My question is I found a good 1990 350 from a Camaro and was curious if that would work since its a different model year and "sort of brand". Someone told me the pontiac motors were different form the chevys in the 90's....
I know there is a difference in the ESC Module between 80's and 90's thirdgens, so I'm told but is that a problem for a 91 350 to a 90 305? I guess there was a internally and externally mounted ESC module which was based on the year. Is that a problem for this swap?
Basically I just want to make sure I can do this without any major problems or anything special I have to do other than new chip?
Also my firebird is a manual, does that cause any issues if it came from an automatic?
Thanks

As far as bolting the engine in, it will a straight swap if both engines are TPI.
There are few parts that you will need that are specific to a 350 like the knock sensor. the 305 computer will probably run the 350 OK but it will need tuning to run perfect since Fueling will probably be a little off. So may want to read up on tuning and learn to do that or buy a custom burned chip since there is no factory 350TPI/5speed computer.
