340 Build Advice

How are you gonna deal with the massive tirespin that even 280hp brings?
A streeter with street gears, and an automatic transmission is a two gear/one shift car.
With 3.91s and a 5500 shift, your speeds at the shift are about;
42/71/103. When you shift into Second at 42mph (no tirespin) the Rs will fall to about 3250, with a typical street stall. What good will your 500@5000/5500rpm engine be, at 3250? You won't get to the power peak again until say 5000/65mph. Which is good gearing, but the tirespin will kill your ET. You might as well have half the power ...... and not have to deal with as much tirespin.Jus saying
I run 3.55 gears and I'm even considering switching to 3.23. There's really no need for me to run anything like 3.91, I'm not drag racing the car. It's a driver and may see occasional autocross. Do you think the car is gonna spin out the tires that much? I run one of the widest tires a non-tubbed/spring relocated dart can, 15x8's.
