I currently have a '77 Camaro with a (leaky) 350/350 turbo. The car is mostly street driven only on weekends, but will see 5 or 6 autocross events and 1 or 2 track days a year. Also, maybe 1 or 2 road trips about 4 hours long. As a starting point, I'd like to get in the 400 h.p. neighborhood at the crank. My (er, actually my wife's) budget is $4000. I have a line on a wrecked 2000 Camaro with the LS1/T-56 combo for $1500. I own a steel fabrication/machine shop that could do a lot of the parts like engine mounts, fuel tank mods, crossmember mod..., so I could save some bucks there. Buuuut, sometimes the thought of a new 383 that would use my existing serpentine drive, headers, A/C... is very appealing and seemingly a lot less headaches. I'd love to be able to drive the car again in the spring and don't want to be in the middle of a swap when warm weather rolls back around. I know the pros & cons of swapping each engine, but I could use a nudge in one direction or the other.
