ok whats the difference between ss 4000 yank and a pt 4000 yank? Would it be to big for a daily driver? My set ups are torquer 2, headers, bbk, intake, p&p tb, 373 gears, tsp lid and k&n filter. Or should I go with an ss 3600 yank or am I going to regret it and want more?

 

The SS will be more friendly for daily driving, but with 3.73's I'd say go with the PT. I had the SS4000 and upgraded to the PT4400 and IMO it's superior in just about every way. I don't have track data unfortunately, but on the street the PT was a definite improvement. It has significantly more topend than the SS, but it's also going to be looser. The SS4000 has a 2.6 STR while the PT4000 has a 2.25 IIRC. The SS should hit harder out of the hole, but the PT still hits plenty hard. They're both great choices, and if your future includes nitrous, the PT really isn't an option. But if you're wanting max performance and topend, PT all the way.
