2.73 to 3.42 with 200R4 thoughts?

My 76 TA with 400 is 90% street driven but runs mid 9's at the local 1/8th mile track. I'd like to get to 9.0 or quicker but I'm reading mixed reviews. Some people say the 2.73 is just as quick but it seems those people are often running 455cu+ with 400+hp. I'm running about 220-240hp and figured the 3.42 would help quite a bit and I'd pair that with a 200r4 so I don't lose hwy driveability. A rear end change and 200r4 conversion would probably be $4k but trying to get 400hp out of my engine would be twice that. Any thoughts?
