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 ?
