A 250 sounds like a good plan, with 9:1 compression and a few bolt ons you'll have nearly as much torque as a V8. Not to mention the durability of a block with 7 main bearings.

The hood clearance will be close and the bellhousing will probably be close to the firewall as well. The best thing about the 250 (other than about 40 ft. lbs more torque) is that it has the same bellhousing pattern as the V8. So you could put an AOD or a T5 behind it and have a good setup for the highway. The C4 is a great transmission but on the highway I feel like I need higher gearing. With a 200/C4/3.10 rear end I turn 3k at 70mph. If I had a 3.00 or a 2.79 it wouldn't be so bad I guess but it'd be a dog off the line.

Do you have a crossmember for the C4 swap already?
