I'm thinking about putting a T5 with a 4.03 1st gear behind a stock rebuilt 235 and a 3.42 rearend. I've done the RPM calculations and it looks good on paper, but before I commit to this setup I'd like to hear from someone who's done this combination already, or something close. Are you happy with 1st gear acceleration AND performance in overdrive? Would you do anything different? What diameter tires? There's no substitute for real life. Thanks
