yes you can but if you can put an ls1 why not put an LS2? get close to 500 horse power... if you can afford it
If it is the LS1 why bother? If it is a V6 than you will have to mock up the motor mounts to the right place. You will also need a trans, driveshaft and modifications to the fuel system.
Yes it can. I put a 5.7 in a s-10 with a corvette intake. Hard work but I did it
No.
sure if you change the motor mounts.
yes
yesyou can change just 1 you dont have to change both
Yes, they came stock. That's incorrect. the LS1 didn't come out until late 97 almost 98. The Buick Roadmaster came stock with a 5.7 litre 350 cu. in LT1 motor the option was the 5.0 litre 305 cu. in motor. The LS1 replaced the LT1 as the LS1 motor got better mileage and more horsepower. And the corvette was the first to get this motor. That's not to say that someone didn't put one in a wagon and swapped out the motor.
If you have the know how you can put anything you want in it.
I would go to the local tuner shop the most trusted shop around and talk to them about it. but what i would say is sell your v6 and get your self a V8 LS1 camaro / Firebird. if you are going to mod anything i would rather put money in a LS1 or LT1 if you want to ever go to a track and have fun smoking other ppl.
Sure can
Yes you will need V8 motor mounts.
