is the car your daily driver?
Buying someone else's already swapped car for sale is always less expensive than building your own, let alone paying someone to build one.
Another option is to find someone's partially swapped car and finish it. There's always people selling a 3800 project. Expect to pay anywhere from $2-5K for a swap needing work.
I could help, but you're about 4 hours away and I'd rather go fishing than work on a fiero most of the time. That's why I have an LS4 sitting in my garage. However, I'm one that would do a swap from Dec-Mar. I fish less then.
