Let me explain it this way. You may believe that you will run high 11's/low 12's on $2500, but you will find out it's alot more expensive than you think. You will not make more power than a decent 20B swap will without going with some sort of power adder or a massive build on the motor. For the 13K that you are speaking of, I can make a fresh built 20B put over 800 to the ground - safely and reliably for more than 70K miles. For your $2500 figure, you can only run an older LS1 in stock configuration. If your going to do the swap, get a newer more powerful LS1. You will need the tranny, harness, and ecu. Then you will need the subframe, a custom driveshaft, custom exhaust, oil coolers, better radiator, lines, fuel system, etc. You will end up spending a lot more than $2500 to make a lot of power. Personally, if I wanted the older LS1, I'd just buy a Trans-Am, Camaro, older Vette, etc. All of them are great cars, and it's a lot easier than a swap (aggravation of the car being out of commission, lost time, etc.). If you just want to do the swap because you want it, by all means go for it. I've got friends with various V8's in their FC's - and all of them spent a lot more than they thought it would be, and none of them are as fast as they thought it would be initially. But - all of them sound great. The rumble of the V8 really catches people's attention.
