If you don't want to fill a nitrous bottle all the time, I would recommend installing a set of ported 1965 289 cyclinder heads (54.5cc combustion chamber). After seeing an article in a magazine, I installed a set on my car for about $600.00 (including all machine work) and cut .85 from my e.t. Oh yeah install a 155lph fuel pump, your going to need it. I did all the porting myself. Current best e.t. is 12.38 @ 110 MPH!!
