EFI , OD, LSX swaps in the name of MPG...
Far from me the idea to start a war with tech lovers....
In a thread I started on TC about building a fuel miser BBC 454 with a 2004R and mild gears for my 1970 non-Pontiac A-body  Or going with a fresh '07 LS2 out of a TBSS thats been sitting on my shop's shelves for a little while, supposed to go in a Jeep Wrangler project collecting dust. The idea was to build the said A-body as a simple, long hauler , road tripping machine since it has two comfy bench seats and a large trunk for luggage. We all agree that the LS has more potential for MPG but at what cost ? Complexity, expensive and labor extensive swap, mix mash of parts etc etc... A mild BBC 7.9CR with an economy 220 @ 050 .515 lift HFT 112 Cam, small tube headers, and Qjet with hot HEI would run on 87 cat pee... Same can be done with a Pontiac 455 or else... Using small gears or OD like a 2004R this thing would get 20 MPG hwy for sure... The question with technology for sake of MPG is : Is the Juice worth the Squeeze ?

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.
