How much horse power does a 1969 Pontiac GTO have ? 1969 gto had seven different block codes and a total of four different horse power ratings as follows: WS @ 366 hp, WT @ 350 hp, WW @ 370 hp, XP @ 370 hp, XX @ 265 hp, YS @ 350 hp, YZ @ 366 hp. The 366 hp were Ram Air III motors and the 370 hp were Ram air IV motors. All WW blocks were manual trannys and the other block codes were automatic trannys.
I bought a 2006 hood for my 2004 GTO and it fit perfectly. No problem what so ever.
it depends on the year model and the engine size,for example the 64 gto tri power 389 cu. inch had 348 horsepower. the 69 ram air 400 gto had 365 horsepower with the right heads and carb combination. The '04 models are rated at 350 hp, and the '05-'06 models at 400 hp.
The automatic transmission in the 2005-2006 GTO was the Hydramatic 4L65E, as opposed to the 2004 GTO with the Hydramatic 4L60E. The manual transmission was for the 2004-2006 GTO was the Tremec T-56 with M12 gearset.
Assuming you are inquiring about a 2004 + GTO ... you can add between 120 and 400+ horse power. It really just depends on you needs (and wants!) and how much you are willing to spend.
