After asking a lot of questions and doing a lot of independent research, I have come to the conclusion that it will be better for me to swap in my 327 in place of the 2.8L in terms of bang for buck. That's mainly because I already have a 327 and a V8 Camaro donor car.

This is not to say I will not swap a 2.8L back into the car one day. The prospect of a 400 hp turbo V6 makes my mouth water. Unfortunately, it also makes the cash register ring uncontrollably.

I'd like to thank everyone who responded to my posts. I have learned much from you and deeply appreciate it.

Cheers!
