doesn't sound unreasonable if they are doing any more than dropping an engine right in. If they have to fab up some mounts, exhaust, reroute wiring, and keep the stock look. Personally I'd drop a v8 in there if he's having all of that done, but then its not my car. If it were a straight up swap with no relocation of lines/wiring/mounts/exhaust then its a bit steep. Hell it might even be a good deal if they are also swapping out the trans(if I remember correctly, the original trans wouldn't be able to handle the power/torque of the 235).
