Can anyone help with a couple more front end questions? Are there any major concerns I should be worried about if I were to install new front springs that will lower the car 1-2 inches? Also, I noticed some of the parts distributors group the Firebird with the Camaros and list a big block and small block application. Would a big block Chevy be closer in weight to a Pontiac engine. I am looking for a 400 - 455 engine to swap out my 350 with so that would be the engine size I want to match the springs with. Thanks for any info that can be provided.
