IN MY 73 LAGUNA, WOULD I NEED TO MODIFY TO FIT THE 454 INTO THE ENGINE BAY ? BECAUSE ITS THE SAME SIZEZ CAR AS THE S3 MODEL THAT HAS THE 454.

1973 Chevrolet Chevelle

Can a 454 be dropped into my laguna that came with the 350. Its the same size as the s3 that had the 454.

Nice conversion. Did many of them. Yes, it will fit like a glove. You need the correct motor mounts for it to work but with the multiple mounting holes on the frame, it is easy to do.

You may need to change the front springs for the extra weight. Make sure you do up a trans to cover the extra power and a set of 3.73 gears will make that car fly.

Good luck

Ok, so what would I need in total for the swap to the 454? Obviously the motor and trans complete, both sides of the mounts, and what else?
