If your wanting a STREET/strip car, a 49/44 would be ideal. Excellent street mannors and plenty of punch for that two or three trips to the track every year. If you want a street/STRIP car, I have seen up to a 70 series work when matched with the proper converter. You need to ask yourself - honestly - what you want. I'm asking myself that question right now. Do I want my street car than I can race and beat most of the cars at the track, or do I want a race car that I can drive on the street.
