I've done it with my 96 - ASP pullies with built in damper, BBK off road 'h' (stock ex. manifolds, stock mufflers and tailpipes), 4.30's and slicks.
At first I went with 4.10's and did not heed the advice of the fellows on the Corral board. Well, they were right the 4.10's were not enough for the DOHC especially on the street. I had the 4.10's taken out and they had only 5,000 miles on them (still have 'em). The 4.30's were installed are just about the perfect gear for these cars. You have that tall fifth gear for cruising and first gear is not a waste from a dead stop. At the strip the 4.10's are pretty easy to bog coming off the line whereas the 4.30's allow the car to 'pull' itself out of a launch much, much better. Don't fear the gear.
With over 600 dragstrip passes (9,900 miles) on my cobra and some heavy duty launching lately I had a Detroit Locker differential and Moser axles installed. Good thing too. With all that racing half of the splines on the axles were worn off and the remaining splines had a slight twist in them.
Good luck. My advice would be to locate a DOHC near you with 4.30's and ride in it and, if possible, drive it. That's what I did from the beginning only the car was equipped with 3.73's. I couldn't tell it had even had a gear change and knew that gear would be useless.
