First let me tell you the mods: 98 gtp w/ 05 l32 longblock,stock heads(w/ short sides cleaned up)comp cam 210/220 .531"/.531 115 lsa,130# crows,comp pushrods,ls7 lifters,stock rockers,fully ported gen3 and lim,stock tb,FWI,pacesetters,catless 3in back to stock mufflers w/cutout,Short stack intercooler,al103 plugs,180 t-stat,42's
running 18 degrees with 11.5 afr on a 3.0 pulley with no kr it put down 272whp/283wtrq in 2nd gear on a dyno jet dyno. Tried adding timing and leaning out really did nothing.
im not looking for all out dyno numbers, they just seem low compared to others mods. What do y'all think, is something not right or am I just crazy.
