I'm ready to order my rossler 4L80 trans. He offers many first gear options. I haven't spoke with him yet cause I hate tire kickers bugging me at work. 3100-3200lbs 66 nova drag week style build, the engine I have now should be 1200-1300 crank HP with twin turbos on E85. With plans of 1700hp later on. 275 tire with leaf springs. I've researched SLR and have come up with many different answers. I'm thinking a 2:10 first with a 3:70 gear for the first go around. What are your thoughts and I appreciate the time. BTW this is a new build and the engine has a small hydraulic roller limiting the rpm to under 8,000.
