New Motor for the Cuda - MRL Performance 340 Stroker

My engine has very similar specs, but I'm about 20% street 80% race and I use a 4.10 gear. I have a PTC 8" converter in my 727, works great. It flashes to 5000 RPM, but drives around town nicely. Since you are more street you will probably want a tighter converter...probably in the 3500-4000 range....but I would call a reputable converter company (take your pick), give them ALL your car and engine specs and let the experts tell you what you need (probably a 9.5").

The right converter/tires/suspension and the power you have, you could be in the high 10's...with the wrong converter/tires/suspension, you could be in the 12's.
