As far a the gear ratio thing goes, the R/T needs to replace the valve springs and get the rev limit raised to 6800 so it can shift at higher rpm and also recover at higher rpm, that will help keep it out of the 1:1 shift. I can cross the traps with my stock size 20's at 6800rpm in 2nd gear at 95.xx mph, that is getting me about a 13.9x. I am now running out of rpm as the truck is ready to run faster, I think I need my tuner to give me 7k, that should allow me to run mid 13's with that tire. My best time with my 26" dr's and current set up is the same as my stock 20's, so there gear ratio really makes a difference.
No I will never waste my money on a ported tb..biggest waste of money ever. Are running stock cam revving tht high? I would be scared haha
