The proper size lead/acid battery to fit your underseat battery box is a Group 2. Any such battery in good condition will have plenty of capacity to readily start your car reliabily as long as the connections are tight and clean, cables are proper size, and the starter motor is in good condition, so chances are your problem lies in one or more of those areas. Starting problems with an electrical system in less than proper condition will be increased if you have Pertronix installed.

Note that speed of rotation isn't necessarily a critical requirement for starting an engine, starting by hand-cranking demonstrates that.
