So ive heard a lot of discussion about sbc v. sbo from a performance point of view...what are some opinions on the more practical side? I have a stock 307 with the shitty metric 200r 3SPD transmission. Now i not only need to know which would be more practical (cheaper in the long run, better on fuel, need durability and reliability as much as i need power), but also which combinations I can go with that will fit properly onto my car (which engine matched with which transmission-200r4 v. 700r4- also which transmission length goes with which engine, etc., etc.) I need the car to get decent gas mileage and be able to handle everyday driving as well as make a trip from Louisville to Chicago on a tank of gas (I used to drive a 2000 Cadillac SLS with 17-25mpg city/hwy Im pretty sure and that car could make the roughly 300mi. trip on about 3/4 tank, so that can serve as a benchmark). Since Im going to be trying to have a lot of this work done professionally and at one time, I really need to make sure I get this right. I hope I was specific enough.
Thanks
Also, I will be looking to put on a posi rear end either 7.5" or 8.5" or Ford 9"(whichever I can find) with, hopefully, 3.42 or 3.73 gears(GM) or 3.40-3.70(Ford).
