Stuck at 55
Alright I have a sbc powered 1964 triumph spitfire. When I'm going down the road the fastest I go is 55 with the motor full tilt. Chevy 350, 350 trans going to the stock rear end. I think my problem is the rear end gearing. Any other ideas and any ideas of what kind of gearing I should look for if I should swap the rear end? EDIT: I can feel the car shift through all 3 gears while idling down the Street, which is what pushes me to gearing. Usual suspects on the trans like vacuum modulator and governor check out and are fine. Tach is squirrelly but at best it's reading around 3300 rpm
