I recently purchased my 1980 Trans Am and am looking for some opinions. I am planning to build a strip/street car and am looking for (obviously) a decent amount of power. My first question is how much work would be involved in swapping the PSB 301 for a PBB 455? I keep hearing people tell me it would be the best engine, but I wasn't sure what all is involved with swapping from small to big blocks. Also was wondering if it would be more effective to maybe just stick with a 400 and just keep in the small block "family"? Thanks for any help
