looking for #'s with new heads well i just bought some stg 2 as heads. i plan on putting them on the car soon. last time i dynoed i had 351rwhp/353rwtq with a 224/230 .567/.572 112LSA, y pipe, lid,headers, spec stgIII. now i have true duals w/ x-pipe and soon the heads will be on. what kind of gains should i see with the new heads. i havent gotten an ls6 intake yet, and the only free mod ive done is cutting the bottom of the air box. my last run at the track is in the sig
What heads did you get? Id say w/ LS6 intake, ported TB, ud pulley, and a good tune you should be around 425rwhp or more assuming the heads you got flow 300cfm or more and have 2.02 / 1.57 valves etc etc.. That cam with all the bolt-ons wouldve had you at 375-380rwhp prolly w/ stock heads. Just my humble opinion. Of course if you sold the heads and got all the above mentioned bolt-ons w/ a more radical cam you'd be at 425rwhp w/ stock heads.
