SPARE 455 BUILD UP
HI GUYS, I HAVE A ORIGINAL 455 ENGINE IN MY TA. I HAVE A SPARE TO REPLACE THE ORIGANAL, IT IS A 73 455. IWAS THINKING EITHER AD 6X HEADS AND A 041 WITH RHODES. OR LOWER COMP AND A XE 274 WOULD THERE BE A LARGE POWER DIFFERENCE? THANKS, BLUE TA

what year trans am?if 73-74 look for the small chamber 4X heads.with them you will look stock and you don't lose that much over a 6X head.
i've ran 455+.030,small chamber 4X heads,rework performer to look stock,ram airIII exhaust manifolds,summit 2802 cam and loved it. to help you pick a cam,the guys here will want to know trans type,if auto what converter,rear gears and what kind of driving are you planning on.

I JUST DONT WANT TO BREAK THE ORIGINAL ENGINE THATS WHY IM CHANGING. I LIKE THE 041 6X DEAL, BUT THOUGHT THE LOWER COMP ENGINE MIGHT HAVE NICE POSSIBILITYS WITH TODAYS 91 OCTANE. THANKS ,

As Warbird said we need more info but the 6X heads with some porting will work very well. If the car is mostly street driven you may want to re-consider the 041 and Rhodes lifters. It might be a little much for the street but maybe not.
BTW, turn your caps lock off and STOP SHOUTING. Stewart

ok, im not shouting. the car will be 60/40 street strip. i thought staying with 8.5 8.75 comp might work well with the xe 274 cam. i also want to use the cheapest gas possible. i was hoping for 12.90s or better with the combo? thoughts. thanks blue ta

The PY Online Forums is the largest online gathering of Pontiac enthusiasts anywhere in the world. Founded in 1991, it was also the first online forum for people to gather and talk about their Pontiacs. Since then, it has become the mecca of Pontiac technical data and knowledge that no other place can surpass.
